KVM crashed on load of Guty Tribe 5 Live CD on Intel 2.6.22

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

This issue remains. If I try to load the Ubuntu 7.10 livecd in KVM on Ubuntu 7.10 I get

$ kvm -localtime -cdrom ubuntu-7.10-desktop-i386.iso -m 384 -boot d

This error does not occur with (k)qemu.

This error mean: your CPU do not have some virtual-registers it should have and kvm can't emulate it.
bad news: kvm team know about it but there is no work on this issue or it is in low priority.
good news: boot loader seems to be fixed now and latest hardy livecd can boot on kvm

My CPU is Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz, for the record.

This is a well-known issue. I'll keep this bug open to track it in case upstream finds a way to work around the limitations in intel's virtualisation extensions.

Thanks for the bug report. Anthony Liguori confirms that this has been fixed upstream, and is clear in Jaunty.

And actually, to be accurate, the actual cause of the bug was another bug:
 * https://bugs.edge.launchpad.net/ubuntu/+source/kvm/+bug/140713

This bug was fixed when that one was solved.
