Comment 8 for bug 795717

I tried many ISO's and the systems that worked before I did a dist upgrade failed to boot also

I just tried it with 2 cpu's and 2GB of ram and it still failed.

I do not get to a point where I can get dmesg output but I have included a screenshot

I have reproduced this issue on a Dell R710, 2950 and R610.

I installed with the 11.04 Server ISO image.

Re-installing 10.10 server allowed the guests to boot as did dropping the vcpu number down to 1

Here are the ISO images I was using for the guests.
