I have Linux Mint 13 Maya 64 bit installed on my PC, with LVM for / and /home and future domU guest systems. I installed the Xen hypervisor via synaptic but I can't boot it: It stops booting somewhere at the point when it discovers the memory. Here the screen output:

Is there a problem with the Xen 4.1.2 with Ubuntu or Linux Mint 13. I have the 3.2-26 kernel of Linux Mint.
P.S.: I had installed Linux Mint LMDE with a Xen kernel before and it did work! But with LM13 Maya it wouldn't load and freeze the computer.
Hardware: Asus Sabertooth X79 with i7 3930K C2 stepping (VT-d enabled) and PNY Quadro 600 GPU. Memory is 32GB and has been tested and works flawlessly. I don't think it's the hardware as LM13 works perfectly.
I guess it was one of these UEFI issues. Formatted the boot drive (/dev/sda) to MBR and installed Linux Mint 13 Mate 64bit with Xen hypervisor 4.1.2 from packages. Installed Windows 7 Pro 64bit as HVM guest with VGA passthrough using a secondary PNY Quadro 2000 adapter (the Quadro 600 card didn't work - no VGA passthrough support out-of-the-box).
Linux and Windows run now side by side and I can switch between them at the press of a button on the USB KVM switch. And I got full graphics acceleration under both systems.
I added a cheap AMD 6450 graphics adapter to be used by Linux, and connected both the primary and secondary adapter to my screen. Set up my screen to activate the last detected DVI input signal (when I switch between Linux and Windows).
