CentOS virt - Mar 2015 - CentOS 6 VM image for paravirtualizaton on CentOS Xen server

I'm looking at a CentOS 5  Xen server that I'd really like to put some
more recent VM's. There are reasons not to touch it at the moment, so
I can't upgrade it in place today.

Has anyone successfully installed a CentOS 6 VM, paravirtualized, on a
CentOS 5 Xen server , without significant Xen upgrades? If so, can I
get a copy from a reputable source, or one that I can review before
using? I'm having a bit of difficulty arranging a PXE enironment to do
a paraviirtualized installation with, and there are apparently
difficulties doing a paravirtualzed system with CD or DVD installation
with Xen.

Yep, CentOS 6 VMs run just fine on CentOS 5 Xen host.

I've got CentOS VM's running fine, and have done them before. But
previously, I deployed the same base OS on the VM as on the Xen
server, so paravirtualization posed few risks. And I had control of
the DHCP setup. so I could trivially set up a tftp server to do a
non-CD installation, because Xen, at last look, doesn't support
installing a paravirtualized host from a CD image.

So I'm right back to my effectively unanswered original questions. So
please: I asked a very specific pair of questions, and they remain
unanswered. CentOS 5 Xen server (hypervisor, or Dom0, whatever we want
to call it this week): Does CentOS 6 work, paravirtualized, on such a
server? And given my deployment issues, does anyone have a base OS
image I can get a copy of?
