RE: Red Hat dropped XEN

["Venefax" <venefax@gmail.com>]

I was trying to use some of the command set, like "xm new -F" etc., and it
did not work, so I did checked and the xm options are limited, compared to
SLES 10 SP2 or the Beta SLES 11. It is an inferior product. For example,
what I typically do is this:
Create a paravirtualized domU
Xm list --long domname > domname.sxp
Edit domname.sxp and add (cpus 2-15)
Xm new -F domname.sxp

The question is: how do you achieve that with RHEL 5.3? I don't want my
Dumu's to use all the CPU's, since I restrict Dom0 to CPU's 0-1. Is there a
way, at all?

Things are not quite that simple. The RHEL-5 userspace tools are mostly on 
a 3.0.3 base, while the hypervisor and kernel are on a 3.1.0 base. The base
versions are typically not upgraded during the lifetime of a major RHEL
release series. That said, we do have a large number of carefully backported

features & patches from newer versions, eg to add support for NPT/EPT, 
improved HVM support, hugepage support, and much more besides.  So just 
comparing version numbers won't give you a true picture of Xen features 
available in RHEL-5.

Daniel
