Hi, When I specified -t (or -q) option with virsh command, the result is something wrong. It is likely to be caused by the way to parse the virsh options. (example) I would like to know the node information with timing information. So, I try some cases. 1) virsh with "-t nodeinfo" ran virsh interactive terminal. Hmm, I didn't expect that... # virsh -t nodeinfo Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # 2) virsh with "-t aa nodeinfo" I got the node information with timing information. But what does "aa" option mean?? (Of course no meaning.) # virsh -t aa nodeinfo CPU model: i686 CPU(s): 2 CPU frequency: 1828 MHz CPU socket(s): 1 Core(s) per socket: 2 Thread(s) per core: 1 NUMA cell(s): 1 Memory size: 1037312 kB (Time: 2.821 ms) 3) virsh with "-t tt nodeinfo" ran virsh interactive terminal. What's the difference with "aa"? # virsh -t tt nodeinfo Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # I think the cause is missing a conditional before getopt_long at vshParseArgv and add to check whether "o->has_arg" is 1 or not. After the fix, I can use virsh options normally. (example) 1) virsh with "-t nodeinfo" # ./virsh -t nodeinfo CPU model: i686 CPU(s): 2 CPU frequency: 1828 MHz CPU socket(s): 1 Core(s) per socket: 2 Thread(s) per core: 1 NUMA cell(s): 1 Memory size: 1037312 kB (Time: 2.626 ms) 2) virsh with "-t aa nodeinfo" # ./virsh -t aa nodeinfo error: unknown command: 'aa' 3) virsh with "-t tt nodeinfo" # ./virsh -t tt nodeinfo error: unknown command: 'tt' Signed-off-by: Saori Fukuta <fukuta.saori(a)jp.fujitsu.com&gt; Thanks, Saori Fukuta.
