Hi Kevin,
While installing a guest into a qcow2 image if the qcow2 image run out
of disk space, the guest will stop work and change state to paused
without messages.
When we tried to free up disk space in the host and the virsh resume to
work. The guest then got I/O errors but later on QEMU also crashed.
A guest in paused state is certainly not the best result.
Probably good way to react are:
- return I/O errors to the guest and the let the guest handle those
(Linux file system code might just crash)
- allow resume only when disk is free again.
What's your opinion?
