[libvirt-users] Strange libvirt exit status 1 (LXC containers)

[Stephen Eilert]

Hello,

I've encountered the following error, trying to start a domain:

error: internal error Child process (PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin LIBVIRT_DEBUG=2 LIBVIRT_LOG_OUTPUTS=2:syslog:libvirtd /usr/libexec/libvirt_lxc --name vm_14 --console 18 --handshake 21 --background --veth veth1) status unexpected: exit status 1

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.
