Hello fellow kvm users/admins,
im currently running kvm-84 with linux-2.6.28.4 under x86_64.
My 2 linux guests are basically running the same kernel (minus iscsi, multipath and
kvm support.
Another guest is a win2008 server.
All of the machines experience the same problem:
After a while i can't connect via VNC, UltraVNC as well as RealVNC
experiencee Timeouts waiting for the server to respond.
All machines show:
(qemu) info vnc
VNC server active on: 0.0.0.0:1
Client connected
It looks like something has died there ... could it be because i
didnt disconnect my VNC Client properly?
Even (qemu) system_reset, will not bring the screen back.
I am open for suggestions.

Looks like the internal vnc server deadlocked.
What does 'netstat -t' show?
Maybe the vnc gurus on qemu-devel can suggest a way to debug this further.
