I have seen this error when trying to bring up bring up a non-PAE DomU on a PAE hypervisor or vice-versa. If that’s the case then it will be clearly indicated in /var/log/xend-debug.log.

Hi!

I also see this error message after upgrading to the latest Xen unstable
changeset 9925 (I did a "hg pull -u" today). With my previous Xen version
(changeset 9515) I had no problems. Going back to 9515 is a workaround for now.

Console error message:
Error: (22, 'Invalid argument')

Config file:
kernel = "/boot/vmlinuz-2.6.16-xenU"
memory = 80

/var/log/xend.log:

Is this a Xen bug?

Cheers,

Open a bug with Fedora on it this morning including log output:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190707

Am I right that this is related to PAE?

Thanks.
