section 3.2

I can boot up into the master (think you also call this dom) xen image.

So everything working so far. The only difference i had to make to configs was that am using vmlinux-2.6.18.

command i am running:
root@ubunut:/etc/xen# xm create baseimage -c
Using config file "baseimage".

Thanks

anyone anyone at all?

[falko]

I'm not sure if
root = "/dev/hda1 ro"
works (in /etc/xen/baseimage). Try
root = "/dev/hda1"
instead.
Also take a look at the configuration files on http://www.howtoforge.com/debian_sarge_xen_3.0.3_p4 .

yes tried that but still same problem

This is what i wrote to xen team but no response yet.

Hey all

i have created a basefile and am doing xm create -c /etc/xen/baseimage and getting this error Error: (22, 'Invalid argument'). Been told it might be to do with kernel version but not sure what version i have or what to use or what version is loading or how to test this?

I went by this tutorial
http://www.howtoforge.com/xen_3.0_ubuntu_dapper_drake
Just changing versions that where there.
and bit of this
http://www.howtoforge.com/debian_sarge_xen_3.0.3_p4

can anyone help me?

Even I am getting the same error,
Error: (22, 'Invalid argument')

and the xend.log file also contains a similar log message.

I dont think there is any problem with the configuration file, as I was able to start a guest domain with a similar config file in another Fedora machine.
