[<command> [command options]...] This needs a tweak, otherwise, executing: virsh ambiguously matches both forms. In general, you should list the shortest possible form first. Also, it seems like passing multiple command strings would be easy to do with this format, such that these two are equivalent: virsh "define D.xml" "dumpxml D" virsh "define D.xml; dumpxml D" So, I think it should be: virsh [options]...

Should any of these be split into separate patches? It's easier to review a series of small patches that each do one thing than it is to review 350 lines of multiple changes smashed together. > > Signed-off-by: Lai Jiangshan&lt;laijs(a)cn.fujitsu.com&gt; > --- > virsh.c | 351 > ++++++++++++++++++++++++++++++---------------------------------- Therefore, I haven't closely reviewed this patch yet, but just from the commit message, I like the direction it is headed in.
