Try adding "noreboot lapic=debug apic_verbosity=debug apic=debug iommu=off" to xen.gz line.

Also add "initcall_debug debug loglevel=10" to the vmlinuz line.

Done, as I'm just compiling another kernel after it finishes I'll post the results.

Is there any centos-frienly or centos working .config file I can use. as  a note I used this http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.32.25-pvops-dom0-xen-stable-x86_64 from

"Xen paravirt_ops for upstream Linux kernel"

Sorry for the big fonts

Thanks again
