I like this patch, but I don't think we can apply it in exactly the
form it is now. There may well be people already using virsh in a
non-root context with Xen, and this will break them requiring them
to add a --readonly arg in. I think we should add the explicit
--readonly flag patch attached, but also put in a simplified
heuristic for the Xen non-root case. I'd think I'd add in a snippet
of code looking like:
if (ctl->uid != 0 && (ctl->name == NULL ||
ctl->readonly = TRUE;
If people agree, I'll apply Rich's patch with this addition ?
