I know that quality, efficiency, stability and security do not exist in 
the Microsoft vocabulary...
Unfortunately almost all users for desktop/workstation use windows (for 
now) and even at the time I still use it for work due to some programs 
that only run on windows (and often are made very badly) :(

I found this error on xl dmesg:

I see a recently posted patch about pfn:
http://lists.xen.org/archives/html/xen-devel/2013-10/msg02028.html
Can this serie solve the problem and I have to try it or has nothing to 
do with this?
And this is the error that cause reboot of domU:

I not found any other error or relevant information on logs but I attach 
them if you want see.
I also tried with Ubuntu 12.04.3, same pfn error on xl dmesg, same 
performance problem (some minutes only for arrive to grub-efi of dvd) 
and after other 10-15 minutes without complete the boot I did a destroy.
Also for that logs on attachments.

Despite windows is bad, it seems that problems persist even in the test 
linux except the shutdown with vcpu issue.
The dom0 used have the installation of this:
http://lists.xen.org/archives/html/xen-devel/2013-10/msg01111.html
Except the git branch used (here the hvm-improve.t6) and the qemu:
QEMU_UPSTREAM_URL ?= 
git://xenbits.xen.org/staging/qemu-upstream-unstable.git
QEMU_UPSTREAM_REVISION ?= master

If you need more informations and/or tests tell me and I'll do/post them.

About legacy bios support that I mentioned days ago I found this 
document about:
http://code.coreboot.org/p/seabios/source/tree/master/README.CSM
Seem that need ovmf change (and probably also on hvmloader) that are not 
able to do.
Thank for any reply and sorry for my bad english.
