Xen : Nested VM

These days I created Xen Hypervisor as a VM for studying. I choosed Ubuntu as a Dom0 distro, followed the Wiki.

To use HVM DomU, I have to set host cpu emulation explicitly because Dom0 VM needs Hardware-Assisted Virtualizaton of the host cpu.

Besides, in xen config file I have to comment out the following line otherwise the HVM doesn’t start.
