Let me try to summarize, please point out if I get something wrong: You have software RAID1 on the host, your disk images live on this device. Whenever checkarray runs on the host you find that VMs become unresponsive. Guests print warnings that a task is blocked for more than 120 seconds. Guests become unresponsive on the network. The fact that the QEMU monitor and VNC still work mean that QEMU is not probably still running the VM. I think the guest kernel is upset, perhaps QEMU needs to do something to help these I/Os along. Please post your qemu-kvm command-line or libvirt domain XML. What's the easiest way to reproduce this?
