Re: [Xen-users] Paravirtualized vs HVM - how big is the performance gap?

[Steven Timm <timm@xxxxxxxx>]

It was possible in the early SL4 (4.2 and later  to use older Xen 
kernel tarballs from xen.org Xen 3.0.2 or so, to run a dom0.  I still
have a couple development machines like that.  But it was
never natively built into SL until 4.5 and then it was only for domU.
If you want a SL dom0 then you should be running SL5.2 or 5.3 which
was just released.  DomU support is available for 4.5 and better.
