[libvirt-users] creating a lxc image to be used with libvirt-lxc

[Spike]

thank you for your help Daniel. I don't get why virt-manager would see a
different /var/run. My container has an ip/ssh, so when I connect with
qemu+ssh from my desktop I shuould end up in the same "space/filesystem" of
libvirtd, not the host one. And I canc onfirm that because I see the logs
of ssh of virt-manager trying to log in. In any case I will try TLS/TCP,
that's fine with me. I seem to also be having another problem: for some
reason I can't get rid of virbr0 and make libvirt use the existing bridge
in the container, even after changing the default net-define virt-manager
still sees a virbr0 and fails to start a VM.

thanks,

Spike
