[Fedora-xen] error mounting /proc: any solution ?

Hi,

This problem has been around since September 2006. The last working 
version I used was vmlinuz-2.6.16-1.2133_FC5xenU under 
vmlinuz-2.6.16-1.2133_FC5xen0. The domu I try to run is CentOs 4.4 which 
runs fine under FC5.

The reason I want to make it work is that we have production servers and 
we wish to avoid having to re install everything and migrate a big bunch 
of domains and database etc.

I am trying to run my existing domU with FC6 but I cannot get passed 
this root system problem. I tried with other distros and get the same 
problem, same thing with XenExpress. I am waiting from XenSource to find 
out if they can help but probably too much champagne on new year's day 
is delaying response. If possible I would rather stick with FCX as I had 
it running without too much problem for 18 months but the updates have 
become problematic since September.

I have read many, many people talking about this over the last 4 months 
but not a single solution to the problem, has anyone a detailed howto to 
get it up and running? I tried the faq about initrd, I am no iniscript 
expert and I failed, I tried with binaries, I tried compiling from 
source with many variant, with and without modules (or builtin) etc. 
Alway the same result. All log simply confirms the problem below.

Also, can it be run under a FC6 dom0 on a Opteron if the domU is i686?

Finally, the doc on setting up a VMX is rather sparse, can someone point 
to a more detail howto?

Regards,
