Comment 42 for bug 632696

Serge,

sorry for the late answer, I wasn't subscribed to this bug before, I'll answer more quickly in the future.

As for NFS - no NFS on this machine, and no console.log either. It seems I was confusingly brief in my comment, I wasn't replying to Mandar really, but to the original bug report.

Adding some context... Ubuntu 11.10, running Xubuntu and disk encryption, quite standard otherwise.

I encountered this bug when trying to install windows using the command

virt-install --name winxp --ram 1024 --vcpus=1 --disk path=/dev/mapper/wdgreen-win1 --os-type=windows --os-variant=winxp --cdrom=/media/dumptemp/winxp_orig_sp2.img

which failed very soon. Don't have the original error message anymore, but it was the "chardev: opening backend "pty" failed" one as far as I remember.

I tried the things suggested in the comments of this bug with apparmor, but was unable to get rid of apparmor "DENIED" messages referring to libvirt. I was reluctant to simply reboot because according to some comments this makes the problem disappear (temporarily) without any other action, and I prefer to fix it for good. Running out of time, I finally booted with 'apparmor=0' which helped.

I'll reboot without 'apparmor=0' to see if the problem reappears. I'm happy to try any other suggestions you might have to get rid of the apparmor error messages in case the problem reappears, now that I have some time to experiment.
