I just now did a "git pull" in each just to be sure. When I do an "xm create" I get: Error: [Errno 2] No such file or directory: '/proc/xen/balloon' Searching the list archives told me that this is most commonly caused by not having enough memory available for the DomU, but I have fixed that. I'm pretty sure the problem is that the paravirt_ops Linux kernel puts its balloon in sysfs and not procfs. So I applied Jeremy's patch found here: http://lists.xensource.com/archives/html/xen-devel/2008-11/msg00358.html ... then rebuilt and rebooted. But I still get the message. However, that patch changes a file in xend's sources. Does xm need a similar patch - or should xm be looking at that same python module in xend's directory? I don't know the codebase well enough to figure it out yet, though I'll be investigating while I await your responses.
