The coLinux initrd has only one script to copy modules into a root
filesystem. But your rootfs is encrypted. So, the simple "mount" would
no work in your case.

The Gentoo initrd must have some more programs to load modules and
activate the LVM and encryption. I think and hope. But Gentoo initrd
would have wrong module version (from non coLinux kernel). That's why
modules should have to replace.
And, don't try to use the Gentoo kernel. That would alltimes crash with
BSOD.

Okay I see what I should do, but What if I used the Gentoo
kernel/initrd I have in gentoo for coLinux, would it work?? I'm going
to try it but tonight when I'll be home, I'll try it and report back
the results....

Yes, this should go. Some user have a raid setup running. So your LVM is
similar.

You need colinux with LVM and DM-Crypt supprt (as module or kernel build
in). I not know, what modules you need. Please check the kernel config
[1]. "CONFIG_DM_CRYPT=m" I can see there. But not know what else you need.

You need manualy change the initrd for this. Basic steps are:
- unpack (gunzip and cpio) the boot/initrd from your native Gentoo boot
- View into th file linuxrc, and check how an what modules are
installed. (modprobe or insmod)
- Locate the modules path inside the initrd (lib/modules/...)
- Remove all non coLinux modules. Replace/Add all modules you need with
coLinux version.
- create the gzipped cpio initrd from the tree now.
- Use the new initrd as "initrd=..." for colinux boot.
- For the first start should run with non graphical runlevel, add "init
2" into the colinux config as kernel command line.

The partition should configure as alias in coLinux config, for example:
  sda3=\Device\Harddisk0\Partition3

1. On this step the linux side was never run. We only are in the windows
driver. This helps a liddle more, where we need to search: Not in linux
kernel. It is inside the windows kernel driver.

2. Both errors says, that some will access a page behind the limit
(160MB in your case). The limit checkers traps into the error.

3. Both errors fails with an access to pfn and max pfn.

Was a variable overwritten? Why memory are changed? Or why the requested
pfn number are not in range of max pfn? Don't know. I'm a liddle out of
ideas.

Memory you have tested with memtest. So, the chips are ok.
What physicaly memory recource used your graphics card?
Have you other devices, that used memory regions over 2GB?
Limit the memory size to 1GB, /maxmem=1024 in C:\boot.ini. Better?

Interesting question: Is PAE currently enabled? Press keys LeftWin +
Pause. On System properties a text "Physical Adress Extension" is seen
or not?
Disable PAE in boot.ini. Or if PAE is enabled, enable it. Better?

The output from line 34 would be interesting. Fails it with constant or
random values? Is it one count over the range, or totaly badly?
Start
  colinux-debug-daemon.exe -p -d -s prints=31,misc=31 -f debug.xml
Than start colinux.
If the error comes again, grep for the text "PFN too high" and lets see
values here.

You not need to start linux completely, please trimm down parameters for
all test as follow:
  colinux-daemon kernel=vmlinux initrd=initrd.gz root=/dev/ram0 mem=160

Re: [coLinux-users] Problem with TAP win 32 adapter

[Henry Nestler <Henry.Ne@Arcor.de>]

If you can not ping external sites, I'm afraid, you have a hard
configured firewall from your departments LAN.IT.

This let me assume, you can only surf via proxy?

If you know that you use proxy with your webserver, than must setup
proxy also in coLinux. Type this on linux prompt, with your personal
settings shurely:
  export http_proxy=http://username:password@...:port/
  export ftp_proxy=http://username:password@.../

After this proxy setup, "wget google.com" and apt-get should work.

More hints about apt-get setup:

Re: [coLinux-users] Problem with TAP win 32 adapter

[Henry Nestler <Henry.Ne@Arcor.de>]

Check your network step by step.
- Is network usable from windows?
  Open a command prompt and type "ping sf.net"
- Start coLinux. Is network still usable on windows side?
  Try "ping sf.net" on windows again.
- Check eth0 parameters inside the running Linux.
  Type "ifconfig", you should see the settings for eth0:
    inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0
  Other values would not run. Typicaly mistake would be the broadcast.
- Check the route inside Linux, type "route -n"
  The last line must be:
    0.0.0.0  10.0.2.2  ...  eth0
- Try to get a web page with such simple command:
    "wget google.com"
  You should see

I also found SLiRP to work where TAP failed  (in getting internet working --
I still use TAP to access the host).  You should be able to use dhcp on
SLiRP, that works perfectly for me.

Are you connected to any VPNs?

Try resolving a host in windows, then pinging it in colinux with the ip.
Does that work?

[coLinux-users] LVM over DM-CRYPT ??

[Wael Nasreddine <mla@na...>]

Hello,

I currently dual or actually tripple boot Windows XP with Gentoo linux
and Arch Linux, my hard disk is partitioned as following:

/dev/sda1       10G         Fat32       Windows XP
/dev/sda2       100M        ext2        /boot partition
/dev/sda3       110G        DM-CRYPT

the /dev/sda3 is an encrypted partition ( LUKS Encrypted.. ), over it
I have an LVM array with 12 LVs 2 of them are gentoo and arch roots, I
have home, 2 swap etc...

is there a way I can boot Gentoo or Arch from the LVM array ( that is
over DM-CRYPT ) with coLinux.... it would be excellent if I could boot
it because I'm really annoyed that I can't access any of LVMed
partition from windows, I have to reboot If I want one file... I also
miss Mutt...

Thank you...

SLiRP is better for your first use. Let TAP installed, you can use it
later as eth1 and fast host only access.

Please use "eth0=slirp" in coLinux config.
Setup network eth0 inside running linux as described in wiki:

Hi,

I was trying to connect to internet via colinux.I installed the TAP win 32

I found that the key to making GL work over TCP/IP (e.g. with colinux)
was passing the -Y option to ssh to enable trusting (insecure) X11
extensions.  You may also need to set an option in your
~/.ssh/sshd_config or /etc/sshd_config to allow incoming connections
to run insecure extensions.

I think so too, but it doesn't do anything to help distro installers
and other framebuffer apps, framebuffer support will still be a very
good thing.

True.  Sadly I can't run colinux anymore since I've moved to Vista 64-bit.

OTOH, GL-over-RFB doesn't seem to me to be a very good idea, they are
completely different approaches.  Remote GL is a natural extension to
XWindows, while to make it work with RFB you have to build VNC into a
full client/server API with as many intricacies and difficulties as
XWindows.

Sorry, you have not that cpu. Yours is
cpu family      : 6	<=== c->x86
model           : 15	<=== c->x86_model
stepping        : 13	<=== c->x86_mask

Inside the current kernel 2.6.25-rc3 found this
arch/i386/kernel/cpu/intel.c:33
void __cpuinit early_init_intel(struct cpuinfo_x86 *c)
{
        /* Netburst reports 64 bytes clflush size, but does IO in 128
bytes */
        if (c->x86 == 15 && c->x86_cache_alignment == 64)
                c->x86_cache_alignment = 128;
        if ((c->x86 == 0xf && c->x86_model >= 0x03) ||
                (c->x86 == 0x6 && c->x86_model >= 0x0e))
                set_cpu_cap(c, X86_FEATURE_CONSTANT_TSC);
}

If I read this, only TSC will be change for your cpu. But should no
depend on the memory bug you found.

I don't know. This is not an "old" CPU (it will quickly become one !-)
but essentially a cheap core duo with a smaller cache.

So... the code you found would mean that linux also has this case
covered and a workaround in place, wouldn't it?

Anyway, I'll try your other suggestions before I post back.
Might not be before a week or so, though.

BTW, thanks a lot for your dedication in releasing and
supporting colinux, Henry.

Yes, of curse. But, perhaps windows does some special workarrounts to
fix the buggy cache on your cpu?

Intel P4 and Xeon was old candidate for problems with caching long time
ago. Has Intel a new buggy chipset now? An idea only.

I found inside Linux kernel:
arch/i386/kernel/cpu/intel.c:31
void __cpuinit early_intel_workaround(struct cpuinfo_x86 *c)
{
        if (c->x86_vendor != X86_VENDOR_INTEL)
                return;
        /* Netburst reports 64 bytes clflush size, but does IO in 128
bytes */
        if (c->x86 == 15 && c->x86_cache_alignment == 64)
                c->x86_cache_alignment = 128;
}

This is exactly your CPU, I'm afraid. You have model: 15 and clflush
size 64. But, I not know how it is interesting for coLinux.

The file can store somethere you wish. You should know name and location
to find it later ;-)

I assume, you have installed coLinux under C:\colinux. If not, replace
the C:\colinux with your installation directory.

Open a Windows command prompt, and type

  cd c:\colinux
  notepad colinux.bat

Than type the two lines into the new opened text editor, for example

  cd c:\coLinux
  colinux-daemon.exe -t nt kernel=vmlinux cobd0=ubuntu.img
root=/dev/cobd0 eth0=slirp eth1=tuntap

Close and save the file "colinux.bat".
In the same Windows command prompt you can than start this batch by typing

  colinux.bat

The batch you should create, to save all the settings some. That is
better, as typing this command line every time you wish to boot coLinux
again and again.

After Linux is booted, you have an english keyboard layout.
The step 5 helps you to select your keyboard type.

Yes, someone was blind here. But was long time, heared from him.

The importend you needs to know is the parameter

  -t nt

This opend coLinux as text only mode, named NT-console.
Without this paramter coLinux starts with a graphical FLTK console,
screenreader can not read/speak such.

Re: [coLinux-users] [coLinux-devel] Fw: Virtual Machine OpenGL

[Agustin Pizarro <aguspiza@ya...>]

You are right Xen needs special care and may be the main reason, but that software is useful on Vmware and VirtualBox too. I think it is on colinux too.

>From my experience getting non accelerated OpenGL (MesaGL) from colinux is not an easy task. Getting HW accelerated OpenGL even with commercial (expensive!) X-servers has been impossible at least for me. Even Cygwin/Xserver still has lots of problems with clipboard copy-pasting between host and guest (client-server). So I have been forced to use VNC most of the time (still losing special chars copy-pasting though).

Now it seems that we could be able to get Xgl accelerated desktops with VNC and some (most?) framebuffer applications can be made to work windowed on X-Windows so I see a lot of apps running a nearly native speeds without the need to develop framebuffer. 

I think moving from old VNC to HW OpenGL _easily_ is a good thing. Of course, there may be some apps, mainly games and installers, that would need framebuffer support anyway because they work with framebuffer (fullscreen) only.

To make this work we do not need to touch colinux kernel, we just need to help porting that VNC-GL client to Windows, currently it only work on linux host, on our own benefit.

"richardvoigt@..." <richardvoigt@...> escribió: There already is OpenGL support provided in several Win32 X servers,
both free and commercial.

The framebuffer support in colinux has never been intended for
X-Windows AFAIK, although it is serendipitously working with
X-Windows.  There is however demand for small linux guests with the
ability to run framebuffer applications without all the overhead of
X-Windows.  Also a lot of Linux installers need framebuffer support.

At any rate, OpenGL support in X or vnc doesn't require any kernel
support, so I'm not sure how this is related to colinux or why there
needs to be a special solution for virtual machines hosted on a full
OS vs LAN.

The project mentioned looks to be more concerned with the problems
presented by Xen, which has a separate hypervisor, not reusing a
kernel with existing hw accel support.

Yust in the moment, the wiki is online.

The image files in installer are perhaps a liddle outdated. So, it is
very goot, you have downloaded a more recent image from sf.net.

If you have downloaded and unpacked the Ubuntu image, than should follow
the notes from
http://sourceforge.net/project/shownotes.php?release_id=544248&group_id=98788
That contains all you need to run the Ubuntu. In the end you have a
minimal Linux system, that is usable to install more packages in same
way, as you installed Ubuntu nativly. The packages are not in the
filesystem. Ubuntu use an online repository.

The difference between VMware and coLinux is mainly, that coLinux does
no needs to emulate any hardware, and coLinux is very fair with memory
usage. You can run coLinux with 128MB for simple text consoles. And if
Linux give free some memory, than coLinux give that free to toe host.

Here is one of my fast booted coLinux
http://www.henrynestler.com/colinux/screenshoots/bootchart-async-38sec.png,
that is a SuSE9.0 standard installation on a partition, used as dual
boot and coLinux. VMware would not good run on this machine (256MB total
RAM). More faster boots are Debian 3.0 or latest ArchLinux.

[coLinux-users] newbie trying to get started with colinux

[alex wallis <alexwallis646@go...>]

Hi.
My name is Alex. I recently found out about colinux on another mailing list.
Am I right in thinking that colinux takes up a lot less resources than say 
running vmware?
I'm writing because I have installed colinux, I have downloaded one of the 
distribution options given in the installer, but now i'm not really sure 
where to start with getting everything working.
I have successfully extracted the image that the installer downloaded.
I was also wondering in the ubuntu image I have downloaded is that just a 
basic file system? or does it include packages such as orca.
Sorry for all the questions.
I did try to check the wiki but the site seems to be down at the moment.
Thanks very much for any help.
Alex.

There is no overclocking applied, all default BIOS settings.
The machine has been very stable so far under XP.
I'll try your other suggestions and report back.

This error let me think, the memory (RAM) is unstable. Or any driver or
coLinux driver self changed the area of coLinux variables.

Try one of my ideas step by step:
Check the memory with memtest86.
Change the memory speed slower in bios settings.
Can you change the memory or CPU cache settings inside the bios? Try to
disable the cache.
Can you temporaly disable one core?
Diable the Online-Virus-Scanner, if you have.

How many RAM do you have? Have you shared memory for graphic card? Ones
heared from buggy graphic driver.

What is exactly the cpu model? "cat /proc/cpuinfo"
Ask Google for memory/chache problems on such cpu models.

[coLinux-users] 0.7.2 less reliable on dual core?

[baldyeti <e_fax_t@ho...>]

Hello,

I am not sure this is the place to post bug reports,
bu anyway here's my story. I've been using colinux
for the past 2-3 years. I had very good (stable)
results when my system was an aging (5yrs) Athlon
system (0.6.x then 0.7.1 starting an installed debian)

ABout 3 months ago I built myself a new pentium
dual-core based system, and I am sorry to report that
colinux started to misbehave. I initially used 0.7.1
to start an etch installation, but things haven't
improved with 0.7.2 (0.7.3 untested yet)

What I am seeing is that if I start colinux early
after i log into XP Pro, it generally will work fine
(like it pretty much always did on the older single
core system). If I try starting colinux later, it
will often fail, displaying the error message copied below.
On occasions, it will completely crash the systm - I
don't even get the BSOD - just a straight reboot!
This may have nothing to do with the processor change,
please let me know what systematic tests might help.

Thanks for your attention,
