11:25 a.m.
* bhyve_command.c (bhyveBuildNetArgStr, virBhyveProcessBuildBhyveCmd):
add dryRun mode which doesn't create any devices when enabled
* bhyve_command.c (virBhyveProcessBuildBhyveCmd,
virBhyveProcessBuildDestroyCmd, virBhyveProcessBuildLoadCmd): accept
virDomainDefPtr instead of virDomainObjPtr.
