Re: [libvirt-users] Strange libvirt exit status 1 (LXC containers)
Answering myself. I've enabled as much logging as possible, and asked libvirt to log
lxc. This is the result:
2011-08-23 22:19:08.778: starting up
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

libvir: error : cannot execute binary /usr/libexec/libvirt_lxc: Permission denied
Stil not sure what would prevent libvirt_lxc execution - tested with an unprivileged user
and it was able to run the binary (but not actually start the VMs). The error message seem
to indicate that the 'exec' call failed. Nothing shows on app armor (disabled it)
or other logs in general.

Hello,

I see nothing relevant in syslog, google searches have returned nothing. Starting
libvirt_lxc manually seems to work (the process never returns), but of course the VMs do
not start.
I am at a loss on what to do next. I'm running Ubuntu 10.04, which is itself a guest
system running under virtual box (host is OSX Lion). I've compiled libvirt from git
(using /usr as the --prefix, after removing the OS package), LXC containers are installed
from a PPA, as the default Ubuntu kernel doesn't enable network namespaces. LXC itself
doesn't appear to be a problem, as I can start VMs with lxc-start. Since I required
libvirt's API, using LXC directly is not desirable.
Does anyone have any tips on what I should be looking for? Thanks.
