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

["Ferreira, N. L. (Nuno)" <n.l.ferreira@xxxxx>]

Hi Tim

I have a dom0 server running SL 5.1 (i386), and I was able to install a 
SL 4.7 (i386) domU.
When you say virt-install command/libvirt do not allow, what are the 
errors you are getting?
Cheers,
N.
