Fedora as Xen/CentOS guest?

[Greg Woods]

Is there a trick to getting Fedora to install as a Xen guest? I've got a
CentOS 5.5 box and I have tried to create a Fedora VM (starting with
F11, then F12, then F13) and I run into the same problem every time: it
starts booting from the install DVD (or ISO image, same thing), gets
partway through the boot, and hangs. It hangs right after printing
messages about cgroups.

Yes, I know Xen is older technology (we have a lot invested in our
existing installation), CentOS is not Fedora, this question maybe should
be asked on a CentOS or Xen list, etc. I'm just wondering if anyone here
has successfully done this.
