RE: [Xen-users] domain crashes with xen 3.1 on creation - Error: (22, 'Invalid argument')

["Larry A Weidig" <lweidig@xxxxxxxxx>]

        I just struggled through this last evening myself on a FC6 machine I 
upgraded from the packaged xen to 3.1.  The Fedora xen rpm package places both 
a xen and grub folder in the /usr/lib/python2.4/site-packages directory which 
conflict with the xen 3.1 installation.  Remove (or in my case I moved them off 
to the side) these folders and things will be better.
        Hope that helps, worked for me.

Larry

Subject: [Xen-users] domain crashes with xen 3.1 on creation - Error: 
(22,'Invalid argument')

hi,
i recently installed xen 3.1. i´m using my config created for a domU with
xen 3.0.3. in xen 3.0.3 it worked. i copied the new kernel modules to the
appropriate directory on the domU.

here my config:
---------------------------------
name = "mailserver-FC6"
kernel = "/boot/vmlinuz-2.6.18-xen"
ramdisk = "/boot/xen-initrd-domU.img"
memory = 512
disk = ['phy:/dev/VolGroup00/MailserverRoot,sda1,w',
'phy:/dev/VolGroup00/MailserverVar,sda2,w',
'phy:/dev/VolGroup00/MailserverSwap,sda3,w']
root = "/dev/sda1"
extra = "ro selinux=0 3"
# vcpus = 1
# vif = [ 'mac=00:16:3e:1a:c5:ad, bridge=xenbr0' ]
# nographic=1
---------------------------------

when i want to create the domU i get following error on the console:

Error: (22, 'Invalid argument')


here the log:
