Hello Guys,
When the qemu process becomes hung, virsh will get stuck on the hung
guest and can't move forward. It can be reproduced by the following steps:
1. setup a virt guest with qemu-kvm, and start it
2. stop qemu process with following:
kill -STOP `ps aux | grep qemu | grep -v grep | awk '{print $2}'`
3. run the following command:
virsh list
I think we can add a timeout for qemu monitor to resolve this problem:
using virCondWaitUntil instead of virCondWait in qemuMonitorSend. What's
your opinions?
Thanks!
