Re: [Xen-users] Error: (22, 'Invalid argument')

It was me who posted the earlier problem and resolution.
When I said  "there was an older installation of the binary tools"
what I meant is the following.  There was a rpm version of Xen 3.0.3
installed on the OS by virtue of its being a redhat clone.  I only
made everything work for xen 3.1 when I totally deleted all
the xen 3.03 utilities off of the system, and the kernel too, and
then reinstalled the xen 3.1 kernel and utilities from the xensource
3.1 tarball.

Hi Ashutosh,

I've been suffering the same problems for the last week.  After building 
everything from source it is now working like a charm.
here are a few sources that helped me out:
http://www.nabble.com/Compiling-Xen-3.1.0-src-on-Debian-AMD64-Machine-t4271223.html
 - list of packages add gettext to that list
http://wiki.kartbuilding.net/index.php/Xen_Source_and_Compiling - another list 
of packages to use as refernce
http://www.howtoforge.com/xen_3.0_ubuntu_dapper_drake - dated but a few little 
nuggets (depmod and mkinitramfs)

hopefully that will help you on your path to xen.  Make sure if you have any 
Ubuntu packages install you purge them, as they may end up
causing problems if left in place.

Hi,

I have set up an ubuntu edgy guest domain on a fiesty host domain. The
installation was successful but on running xm create -c baseimage, I get the
following error message:
Error: (22, 'Invalid argument')

The problem seems very similar to the one here:
http://lists.xensource.com/archives/html/xen-users/2007-07/msg00361.html but
I'm not able to figure out what the post means by "There was an old binary
installation of the tools"
