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

We are currently in the situation of needing to use Scientific Linux 4.x
(a RHEL derivative) in paravirtualized mode. The problem is that the
virt-install command/libvirt don't support installing Scientific Linux
4.x (only 5.x) so I'm having great trouble installing SL4.x in a
paravirt domU.
I see 3 possibilities but don't really know if they are realistic so
need people's thoughts on them:
* Find a way to install SL4.x in a HVM domU and then convert that domU
to paravirt mode (I'm trying this now but with no success)
* There is some technique to allow booting of paravirt VMs off of .iso
images or over PXE (or any other method that could lead to a Kickstart
installation)?
* Just run 4.x in HVM mode - roughly how big is the performance impact
and how could I minimise it?
The hardware we're running this on supports AMD-V virtualisation, the
domain0 OS is Scientific Linux 5.3 x86_64.
Thanks
