VM was doing lot of write IO during this test.

QEMU is waiting for librados to complete I/O.  Can you reproduce it with
a different driver?

I'll try.

However RBD is used only as read-only ISO - rbd:iso-images/rescue.iso:auth_supported=none,if=none,id=drive-ide0-0-0,readonly=on,format=raw) - what IO would it have to complete?
