backdoor interface question

[Sergey G. <hq9...@ma...>]

Hello community!

I've got a question (probably a dumb one) about the backdoor interface used in open vm
tools.

The question is - where are backdoor interface specs published? Are
they open? I mean how VMWare let us know
how we have to communicate with virtualware?

Okay, now for some reason
this magic asm stuff with those magic constants work, but who can
guarantee that it will remain to be compatible with newer VMWare
versions?

Maybe I've just missed something.

Thanks,
Sergey

32 bit build on 64 bit system

[Marek G. <mar...@gm...>]

Hi!

I'm trying to build a 32 bit RPM for newest open-vm-tools
(open-vm-tools-2008.12.23-137496) but I'm getting an error. I'm on 64
bit Fedora 10. I successfuly created a 64 bit package, but with 32 bit
I have problems.

I grabed spec file from
http://www.poolshark.org/src/dkms-open-vm-tools/dkms-open-vm-tools-0-1.2008.10.10.fc10.src.rpm.
My modified spec file is here: http://pastebin.com/f5df0055e.

Yes, I believe BDOOR_CMD_GETTIMEFULL is new for WS 6.0, and BDOOR_CMD_GETTIMEFULL_WITH_LAG is new for WS 6.5. With Workstation 5.5.2, only BDOOR_CMD_GETTIME is available.

Re: usecs on host is always 0! guestd problem?

[Sergey G. <hq9...@ma...>]

Hi again,

well the second issue is a bit more clear now. It is because I do like
this:

printf("%"FMT64"d %"FMT64"d", sec,usec);

for some reason the second argument is shown as 0, though it is not 0.
I guess I need to go deeper in preprocessed code.

but the first one still remains:
1.      this is always falling back to BDOOR_CMD_GETTIME case. Why? Is my WMWare too old?

usecs on host is always 0! guestd problem?

[s g <hq9...@ma...>]

Hello guys,

Urgently need your kind assistance!
While playing with time-syncing part of guestd I have faced the following (mis?)behaviour of the block of code provided in the bottom (it is taken from ToolsDaemon_SyncTime function).

I run it on VMWare 5.5.2 with SLED 10 Linux as a host and Fedora linux as a guest.

What I see is:
1.	this is always falling back to BDOOR_CMD_GETTIME case. Why? Is my WMWare too old?
2.	In the end I see that hostUsecs is always 0. What could be the reason?
BUT!!! I just made a test and discover that  this two assignments (that are the same for all 3 cases):
   hostUsecs = bp.out.bx.word;
   maxTimeLag = bp.out.cx.word;

in my case place something that looks _extremely_ like usecs from the host to the maxTimeLag variable (Bug?)

I got rid of all the initialization in guestd, and call this routine right away in int main(). Could this be the reason for this?

Really hope that you help me out. Thanks.

Sergey

I looked up this issue in Debian's bug tracking system and found this bug report:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507629

It's too bad the person who closed the bug report didn't provide much information; I'm still not clear as to why this isn't a problem.

I have this problem on my Debian machine at home as well (which is Debian unstable). Basically, even though Debian's default gcc installation is now 4.3, the Debian kernel is still being built with gcc-4.1 for some reason. From /usr/src/linux-headers-2.6.26-1-amd64/.kernelvariables:

...
CC = $(if $(DEBIAN_KERNEL_USE_CCACHE),$(CCACHE)) $(CROSS_COMPILE)gcc-4.1
...

When building kernel modules through our build system, we first check that the CC you're using matches the CC used to built the kernel. In this case, CC for the kernel was 4.1 and the CC you're using (/usr/bin/gcc -v) is 4.3. You need to build the kernel modules using the same version of gcc as built the kernel, for safety reasons (I believe). So you could relink /usr/bin/gcc to gcc-4.1, or you could pass CC=gcc-4.1 on the command line to your invocation of 'make'.

I also wanted to point out that we have recently released OSPs

Hi,

i'm seeing a vmhgfs compile failure on 2.6.28 rc8 :

mhgfs/page.c:88: error: unknown field 'prepare_write' specified in 
initializer

vmhgfs/page.c:89: error: unknown field 'commit_write' specified in

Does anyone already have a patch for this ?

VMware Tools OSPs

[Ragavan S <rag...@gm...>]

[cross-posting to both the announce and devel lists]

Hi folks,

A couple of days ago VMware announced the general availability of
VMware Tools Operating System Specific Packages (OSPs) for several
Linux distributions. Using OSPs, enterprise customers virtualizing
Linux on VI will be able to install/update/manage their VMware Tools
installations using the guest operating systems' native packaging
format (rpm, deb etc) and update mechanisms (apt, yum, rug, etc).

More details including a list of supported ESX releases, guest
operating systems, documentation and package repository are available
from the OSP web page at http://packages.vmware.com.

Naturally, this is bound to raise several questions related to OSPs
and open-vm-tools. To help answer some of the common ones, we've put
together this short Q&A page on the open-vm-tools project wiki page at
http://open-vm-tools.wiki.sourceforge.net/OSP.

Please take a look and let us know if you have any additional
questions/comments on this topic.

Regards,
Ragavan

RE: Retrieve unique non-configurable host identifier from guest

"The goal is to identify the host that the guest is running on."

And what would you do with this information if you had it?
Bear in mind that the host identifier could change underneath you at any time.

Thanks,

What is your end goal here?  I'm still not certain about your request.
 You're asking for a value from the host, which is the box running ESX.
 However, you're referring to the UUID, which is a unique value that
each VM has.   Are you looking to uniquely identify the VM, or the host
that its running on?


I'm sorry for the confusion. The goal is to identify the host that the guest is running on.

I'm sorry for the confusion. The goal is to identify the host that the guest
is running on.

What is your end goal here?  I'm still not certain about your request. 
  You're asking for a value from the host, which is the box running ESX. 
  However, you're referring to the UUID, which is a unique value that 
each VM has.   Are you looking to uniquely identify the VM, or the host 
that its running on?

I read a post in another forum that the uuid does not change when you move
around your guest.
However, the uuid is configurable.
I would like to have the same property as the uuid, bit it should not be
configurable.
There might not be a such value or identifier though.

If we skip the requirement that the value should stay the same when being
moved around. Is there any value I can read from the host system that never
changes.

I'm not sure I follow this. A unique identifier of the host means each 
host would have a different identifier.  If you VMotion between hosts, 
that would mean the identifier for the host would *have* to change in 
order for it to be a unique host identifier.

Retrieve unique non-configurable host identifier from guest

[David H. <hn...@gm...>]

Hi,

I'm looking for a way of retrieving a unique identifier of the host system
from within a guest. Preferable an identifier that does not change if the
guest is moved by V-Motion.
What I understand, the uuid is configurable by editing the vmx file so this
is not good enough.

I'm looking for an identifier that cannot change without reinstalling the
host system installation or similar.

Does any one have any tips of what I can use?

Thanks
David
