Hi,

I have difficulty installing Ubuntu 12.04 Beta 1 amd64 as a domU in 
Ubuntu 11.10 Release amd64 dom0.

Please watch my Youtube video of the entire installation process here:

My short video clip is about 14 minutes.

I am using open source Xen virtualization. Please advise.

NOTE: Windows XP Home Edition is working fine as a HVM virtual machine 
in Ubuntu 11.10 host operating system.

Thank you very much.

Yours sincerely,
