For our work on accelerated network drivers we're currently using suspend() to give the guest a chance to stop using any hardware resources that have been mapped up into it. Without suspend(), you could be in the situation where the guest was in the middle of accessing a hardware resource when it is migrated to another server where it clearly won't be able to access that hardware resource. With suspend() and resume() we can stop it using the hardware resources it has, then renegotiate equivalents on the the server if they are available, before carrying on as before. Working around this would be tricky. Kieran _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
