BTW: --source doesn't accept multiple values.

But anyway, for that we would need to change the way we parse the
argument value because for instance:

  virsh shutdown --mode agent, fedora

is not viewed as valid command by current implementation:

  error: Unknown mode  value, expecting 'acpi', 'agent', 'initctl',
'signal', or 'paravirt'


The fix for this is pretty simple:

index 9315755990..e3daa7d015 100644
--- i/tools/virsh-domain.c
+++ w/tools/virsh-domain.c
@@ -5847 +5847 @@ cmdShutdown(vshControl *ctl, const vshCmd *cmd)
-    while (tmp && *tmp) {
+    while (tmp && *tmp && **tmp) {


But the question is, should we? I mean, this way of accepting multiple
values is pretty unique. I haven't seen any other CLI tool like it
(except for QEMU obviously) so I don't see any behaviour we could mimic.
And I find comma at the end a bit ugly looking.
