Fix the "times" field type for KVM hypervisor
Fix the "times" field type for KVM hypervisor

The KVM hypervisor Python class returned a "0" value for the times
field, which gets serialized as a string. As Haskell is more picky
about types, this caused the entire response to be declared as invalid
and broke status reporting. Fixed by changing the value to a proper
int.
