Public bug reported:
Running a VM using raw sparse disk image on kvm 0.14 on Debian.
When disk writes use up all disk space kvm locks up.
if it cannot handle this situation gracefully (eg suspend the VM until
space becomes available) it should at the very least report an error and
exit, not keep sitting there.

Actually it should pause the VM - are you sure that KVM is "locking
up"? If you run with SDL the window title says "[Stopped]" and you
can resume the VM with the "c" (continue) QEMU monitor command once
you've rectified the storage shortage.
Are you using libvirt (virsh/virt-manager)?
What makes you think that KVM is locked up?
How much CPU is the qemu-kvm process consuming?

Unfortunately, the window title is not visible at all times so even if
it says [Stopped] it is not useful indication of the VM state.

No.

Nothing apparent happens. eg. the VM mouse cursor does not move, no
messages printed in the terminal from which kvm was started.

Did not check.
Thanks
