Yes, the ability to pause a domain from the toolstack command line was added way back in the beginning largely because... Well, because it could be done, and it was easy! It's not actually a very good idea. You won't actually find the toolstack itself automatically pausing a domain in very many places at all -- most places where it does are debug/diagnostic code, or where a domain is about to be destroyed anyway. So, yes, in short: don't do that! :-) -- Keir > Thanks > L. > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel
