Re: [Xen-devel] Where can I get a balloon driver to test PoD

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

Yunhong: FYI, as of yesterday booting PoD with this kernel doesn't
work correctly, due to some math error.  The balloon driver will
balloon down, but is about 8 megs off.  So eventually the guest OS
will try to populate those pages, and the guest will crash.  I suspect
it probably has to do with libxl not accounting for the video ram
properly, but I haven't had a chance to look into it.
