I am just rebuilding my Xen box (CentOS 5.5), and I thought it would be good idea to install Xen 4.0.1 (from Gitco), instead of 3.4.3 which is what I used to use.

I can't seem to create hardware guests. PV guests are okay. Whilst researching the issue, I noticed this (see below) in xm dmesg.... I found a bug report, but it doesn't say if there is a work-around

(XEN) AMD-Vi: IOMMU not found!
(XEN) I/O virtualisation disabled

Is this the lifely cause of my issue.

Thanks in advance,
