Hi. I found this issue with IA64 box while looking at the c/s of
18204:21dd1fdb73d8, but I believe the things is same with x86 box.
I'm not sure whether this patch coexist with the old ioemu which
is to be removed soon. So it might be desirable to apply
this patch after deleting the internal ioemu tree.
thanks,
xm: Don't spawn vncviewer twice.
Without this patch, vncviewer process remain as follows.
> # pgrep -fl vnc
> 4303 vncviewer -log *:stdout:0 -listen 5501
> 5089 vncviewer -log *:stdout:0 -listen 5502
> 5763 vncviewer -log *:stdout:0 -listen 5503
