Hi,
after a previous thread I start & some feedback you gave to me, about
creating xen VM I ask you for your help.
Here is the problem : `mount`. It was unable to find the disk/device
to mount it as root (/). After the linux kernel bootup (domU)
I create the VM by theses steps:
i''m on fedora 8 with xen 3.1.0-13
a) #fdisk /dev/sda create a new part (sda4) type linux
b)format it with
#mkfs.ext3 /dev/sda4
c)Copy on it all files from my distrib with :
#cp -a / /mnt/sda4
Edit the /mnt/sda4/etc/fstab to meet the reqs for the VM.
d)Start the vm from config file (see below).
#xm create testvm.conf -c
Booom! failed :''(
I check every thing i can, fstab, VM config file & test several
things... But i was unable to fix the problem.
Someone can help me, point out whats wrong ?
Thanks,
---

Try changing this line:

to this:
disk = [ ''phy:/dev/sda4,sda1,w'' ]
I had to do that for my domU''s when I was uing paravirtualization a few
versions ago. I can''t remember if that was all I had to do, but you
might
also try this line (I think it would only be more appropriate in an HVM
environment where the partition had been fdisked as well):
disk = [ ''phy:/dev/sda4,hda,w'' ]

I thought about mentioning this possibility, but I wasn''t sure on the syntax. I am also not sure whether it is Fedora specific or whether the ability to use sda instead of xvda is XenSource specific (aside from in HVMs where you need "real" devices). Alain, in this case was mapper/LaLvg0-MailDisk partitioned with fdisk, or was it just a regularly formatted (i.e. ext3) lvm partition? Also, from your provided line, it looks like /dev/ isn''t necessary after the phy: in Fedora Xen where it was necessary in the XenSource version I last paravirtualized in. Is it accurate to assume that you copied that line from a working config on a Fedora Xen machine?
