Yeah missing details in commit message bites me now as I don't remember if this was only cosmetic change as CREATE and DELETE both use VIR_ASYNC_JOB_SNAPSHOT instead of VIR_ASYNC_JOB_START or if there was any other reason for this patch. The only change this introduces is that now when revert job is running query jobs are allowed as previously no other jobs were allowed. Pavel
