But, if I close the desktop VM, I can't access anymore to the virtual desktop of the VM, it is as if the graphics is freazing.The VM is still alive. What is very strange is that I can connect directly with vnc client on 127.0.0.1 :5900 port. I try to launch virt-manager with " --debug " option, but don't find any interesting errors.

Hmm, I wonder if it's related to this one:

http://marc.info/?l=xen-devel&m=140050749529103

Although since this hasn't even been accepted into upstream libvirt,
AFAICT, it's strange that it works with RH7RC and SLES.

Can you tell what port virt-manager is trying to connect to?
