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

You can run libvirt inside a container - I've done that the same reasons
as you when i wanted to test stuff without messing up my host. It sounds
like you were trying to connect using a virt-manager outside the container,
talking to libvirtd inside the container.
This gets more complicated - virt-manager connects over a UNIX domain
socket at /var/run/libvirt by default. If you're running libvirtd inside
a container, then the /var/run seen by libvirtd will be in the container
filesystem, while the /var/run seen by virt-manager will be the host
filesystem. You'd need to figure out a way for the /var/run/libvirt/libvirt-sock
in the container to be exposed to virt-manager in the host.
Alternatively you would have to make libvirtd listen on a TCP address and
connect over TCP with suitable auth.

Daniel
