[virt-tools-list] Re: live migrate ok with virsh, ko with virt-manager



Ok,
waiting for answers and tips, I enabled the fedora-virt-preview repo
and updated the components.
Now I can migrate from virt-manager, but the vm appears running on the
new host (I can see the qemu process) but frozen from an OS point of
view.
How can I send sysrq to it to see what is happening at its side?
The display of the guest shows the gdm login but nothing happens, no
mouse, no keyboard and no vt switching inside,
ping interrupted...
Any hint on debugging?
thanks,
Gianluca

If I do an strace of the guest pid I get:
