Re: [Xen-users] Ubuntu: DomU hangs on boot

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

Hi, I also have Ubuntu Gutsy 7.10 and having lots of problems with its xen version and 2.6.22-14-xen kernel, including HVM domains hanging at boot. I don't suggest it for use. Unfortunately, the Ubuntu development guys look so busy that they can't also close the bugs that I've submitted (at least an explanation) 1 month ago.

Br, Emre
