One nit: Patch 4 - add an ignore_value() around the "total-time" fetch...

ACK - series.

Ran through 7.5.0 Coverity

FWIW:
My NMI from 4/6 of v1 probably had more to do with trying to swap
between different windows and forgetting where I was...  I think what
happened is I read ahead and saw that the values were calculated and
started deleting a thought and yes, got interrupted (not difficult to do
at times). I was comparing those changes qemuDomainJobInfoToParams for
completeness...
