RBD timeout 0 and QEMU process stuck during migration

[Jiatong Shen]

Hello Experts,

   We are using QEMU 6.2 and Ceph Pacific on production. The ceph mon
and osd operation timeout is defaulting to 0 which IMO means never
timeout. Under this setup, we observe that during live migration if
the RBD network is unstable, the virtual machine could become
unresponsive (for example, virsh domjobinfo command is stuck
indefinitely).
   My question is is there any recommendation for this situation? can
I possibly cancel live migration under such circumstances?
