HI Cole,

I have attached a copy of my virt-manager.log file. hope you find it useful.

You comments on KVM seem very inspiring, and im already set to give KVM a
Before that i would like to know a few things?

-> What is faster Xen or KVM? I am aware that KVM particularly depends on
the processor to support VT, which my processor does
    (Xeon 5000 Series).
-> Will KVM allow me to use multiprocessor support for Windows XP
-> Does KVM support paravirtualization? or does it matter at all?
-> Is the Migration of Xen fully virtualized guest to KVM possible?
-> Can i use virt-manager to manager KVM guests?

I am having a good feeling about KVM. Please help me decide.

BTW, just can't wait to upgrade my system to fedora 10. really excited about
plymouth and the other speed ups in the fedora system. hoping that KDE 4
does not dissapoint me, in which case ill be sticking with fedora 8.
Thanks to all you Redhat guys (an the Community of course) for Fedora 10.
