[User-mode-linux-user] user-mode port 0.21-2.3.99-pre6

[Jeff D. <jd...@ka...>]

This release has a couple of compatibility gotchas in it:

devfs seems to have changed its default behavior in this release.  It now 
doesn't mount itself by default.  So, if you're using devfs, you need to add 
"devfs=mount" to the kernel command line, or it won't boot.

I've started phasing out the block major 62 fhd device in favor of the new 
official block major 98 ubd device.  Temporarily, both names will work.  You 
will need to start using ubd?= instead of fhd?= on the command line and change 
/etc/fstab to mount filesystems from /dev/ubd/* (/dev/ubd* without devfs) 
instead of /dev/disk/* (/dev/fhd*).  Also if you're not using devfs, you will 
need to mknod a bunch of /dev/ubd* device for each existing /dev/fhd* device.

That being said, the new stuff is as follows:

It's updated to 2.3.99-pre6.

The idle loop now sleeps rather than spinning.  This makes it much less of a 
drag on the host when it's not doing anything.

The network device now allows the host end of its connection to be specified 
on the command line as "umn=[ip-addr]".  It used to be hardwired.  This makes 
it possible to run several virtual machines in a virtual network on a single 
physical box.  The sleeping idle loop makes this much more pleasant, as well.

A bunch of signal delivery bugs were fixed, including passing unhandled seg 
faults on to the process rather than having them panic the kernel.

A nasty stacksize limit bug is fixed.
