The QEMU version is 1.5.1,and the KVM version is 3.6

We have the exactly same problem on our NUMA systems. The clock of
windows 2008 guests sometimes just stops and it becomes slow when you
are connected via rdp. After connecting to qemu's vnc server
everything runs fine again. The problem seems to occour more often
when the host is under pressure.
Hi all:
Windows2008 Guest run without pressure for long time. Sometimes, it stop and
looks like hanging. But when I connect to it with VNC, It resume to run, but
VM's time is delayed .
When the vm is hanging, I check the main thread of QEMU. I find that the thread
is blocked in g_poll
