Try to connect via virsh (Libvirt 0.7.0) to Xen.
When you will done with this.
Try to run:-
# virsh create OSOL134.xml
or just try to create Xen guest via virsh. At this point you gonna realize that
the picture you've wrote is not so nice as it seems at the first glimpse.
Virt-install will reject creating HVM guests only PV at the same time.
Actually, you are supposed to work via "xm" profiling for DomU management.
( vs F12 with same Xen-4.0-rc6&(2.6.32.10 pvops)  on the top )
It doesn't mean that i like KVM, however Libvirt 0.7.X-Y is not quite ready
for Xen 4.0 for obvious reasons on both F12 and U 9.10 Server ;)

Boris.

Hi!

 Security, isolation, performance AND stability!  :-D

 My KVM host at my Dell Desktop already freezes two times, I mean, my four guests died, requiring a reboot... I'm on Ubuntu 9.10.

 Now I have the Xen 4.0 with Linux 2.6.32.9 (pvops dom0) on top of my Ubuntu 9.10 working with Compiz and support for PVM and HVM domains...

Regards,
Thiago

Hello,

Given that most well known VPS providers such as Slicehost, Linode etc
are all using Xen instead of other technologies such as KVM, what are
the unique advantages in your opinion?

Performance? Stability?
