Hello,

I have a new problem with Cloudstack. Every 20-30 minutes or so, all
Windows 2008 R2 VMs stop.

The libvirt log says:
2013-12-10 14:40:04.881+0000: 1752: error : qemuMonitorIO:615 : internal
error: End of file from monitor

Which would mean that qemu crashed. However, qemu log says this:
qemu: terminating on signal 15 from pid 1752
2013-12-10 14:40:04.881+0000: shutting down

Which would mean that libvirt killed it (pid 1752 is libvirtd)

The hosts are Centos 6.4 and Ubuntu 13.04, the primary storage is nfs. This
happens no matter which host the VM runs in. Also, there are three Windows
VMs total and they all crash within minutes of each other. For example, VM1
crashed at 14:40:04, VM2 (same host) crashed at 14:40:34 and VM3 (different
host) crashed at 14:35:19

What can be done to prevent this?
