Yes, it is correct. Ubuntu 7.04/7.10 won't work anytime soon. There are few workarounds: 1. use text-mode bootloader 2. use special patches for KVM (not included in mainline, but in Alexander Graf's tree) (this is ugly hack, so it was not accepted into mainline KVM) 3. use special patches for Graphical GFX GRUB But do not worry; newer Linux operating systems 2008 fix this problem with solution #3. i.e. openSUSE 11.x and Ubuntu 8.x won't have this problem (tested with several Alphas) -Alexey "Technologov", Qumranet QA Team Member [-- Attachment #1.2: Type: text/html, Size: 1138 bytes --] [-- Attachment #2: Type: text/plain, Size: 228 bytes --] ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

I didn't see it in the http://kvm.qumranet.com/kvmwiki/Guest_Support_Status Please post the kvm version and the errors you get.
