I applied Alex Bligh's patch (http://blog.alex.org.uk/archives/23) to the stock Ubuntu 10.04 64-bit kernel and was able to balloon up and down. There does seem to be an accounting bug that I am debugging. The check you are talking about is of course not present. It would be a shame if the upstream driver had that check :( Thanks, AP > -----Original Message----- > From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel- > bounces@lists.xensource.com] On Behalf Of Dan Magenheimer > Sent: Monday, June 14, 2010 10:12 AM > To: Xen-Devel (xen-devel@lists.xensource.com) > Cc: Jeremy Fitzhardinge > Subject: [Xen-devel] Linux pvops ballooning pv only? > > I was just looking at the Linux upstream balloon driver > and noticed that balloon_init fails if !xen_pv_domain(). > Why does ballooning not work for an HVM domain?
