As I remember kvm is not really necessary, and test have a comment about it:
# And it didn't reproduce if at least one of the following:
...
# 3. drop kvm and use iotests.VM() (maybe, because of qtest) (however, it still
# reproduces, if just drop kvm, but gdb failed to produce full backtraces
# for me)
But the comment should be updated with this patch.
