Thanks, I tried your suggestion, the results are the same. The
system seems to be unable to find the IDE devices, I am using LVM
devices
IDE
device = hde, 60Gb hd
primary partition = hde1 , volume group = vg, logical volume =
/dev/vg/lvm1 which is a pointer to /dev/mapper/vg-lvm1
When
the /dev/vg/lvm1 device is mounted the Xencommand " xm
create -c vm01.cfg" produces the following
error:
# 'local': the device may not be used because it is
mounted in the
current
#
(i.e. the privileged domain) in a way incompatible with
the
#
requested mode;
This
error is produced by /etc/xen/scripts/block.
When
unmounted the following is shown on the screen:
[root@rhfc401 /]# xm create -c vm01.cfg
Using config file
"/etc/xen/vm01.cfg".

Subject: [Xen-users] Xen 3.0 domain
creation issues on fc4
I made some modifications after
reading the list messages in my e-mail box. I am now getting the following
error:
[2005-12-29 20:05:12 xend] DEBUG (blkif:24) exception
looking up device number for sda1: [Errno 2] No such file or directory:
'/dev/sda1'
I also
get an error on the screen that /dev/sda1 or /mnt/sda1does not exist and I
need to properly specify the boot parameter.
I get this error when I attempt to
use /dev/sda1 or /mnt/sda1; the LVM partition will mount successfully with a
mount command. I moved it to /mnt/sda1 because the os deletes /dev/sda1
on reboot and I have to recreate it with a mkdir command. When I mount
the /mnt/sda1 device and run "xm create -c vm01.cfg" I get an error that the
domain cannot mount because the device is in use.
