Configuration:
Dom0:
Xen 3.1 tarball from xensource.com on top of RHEL5 (x86_64).
First DomU:
Native xen 3.0.3 32-bit pve kernel as shipped with RHEL5 (i386).
Dom0 is up and OK. I am trying to start the first domu.
config file is below:
I try to do
xm create xen1.cfg
and get error message:
[root@fermigrid5 ~]# xm create xen1.cfg
Using config file "/etc/xen/xen1.cfg".
Error: (22, 'Invalid argument')
[root@fermigrid5 ~]#
xm log shows the following.

Here's the config file xen1.cfg which works fine on a xen 3.0.2 instance.
It appears from the log file that it is having some problem with the uuid
which I do not have in this config file.

# Define network interfaces.
# By default, no network interfaces are configured. You may have one created

# vif = [ '' ]
#
# or optionally override backend, bridge, ip, mac, script, type, or vifname:

# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.

# where UNAME is the device, DEV is the device name the domain will see,

# The vtpm entry is of the form 'instance=INSTANCE,backend=DOM'
# where INSTANCE indicates the instance number of the TPM the VM
# should be talking to and DOM provides the domain where the backend
# is located.
# Note that no two virtual machines should try to connect to the same
# TPM instance. The handling of all TPM instances does require

#nfs_server = '169.254.1.0'
# Root directory on the nfs server.
#nfs_root = '/full/path/to/root/directory'
# Sets runlevel 4.

#----------------------------------------------------------------------------
# Configure the behaviour when a domain exits. There are three 'reasons'
# for a domain to stop: poweroff, reboot, and crash. For each of these you
# may specify:
#
# "destroy", meaning that the domain is cleaned up as normal;
# "restart", meaning that a new domain is started in place of the old
# one;
# "preserve", meaning that no clean-up is done until the domain is
# manually destroyed (using xm destroy, for example); or
# "rename-restart", meaning that the old domain is not cleaned up, but is
# renamed and a new domain started in its place.
#
# The default is
#
# on_poweroff = 'destroy'
# on_reboot = 'restart'
# on_crash = 'restart'
#
# For backwards compatibility we also support the deprecated option restart
#
# restart = 'onreboot' means on_poweroff = 'destroy'
# on_reboot = 'restart'
# on_crash = 'destroy'
#
# restart = 'always' means on_poweroff = 'restart'
# on_reboot = 'restart'
# on_crash = 'restart'
#
# restart = 'never' means on_poweroff = 'destroy'
# on_reboot = 'destroy'
# on_crash = 'destroy'
#on_poweroff = 'destroy'
#on_reboot = 'restart'
#on_crash = 'restart'
