I also had this problem recently with regard to some Ubuntu 12.04
domUs, but on Xen 4.4.1, Debian jessie. These domUs worked fine on
earlier versions of Xen. I searched around a lot and found a few
other people with the same problem, but no answers.

In the end I discovered that these domUs were using the
linux-image-virtual kernel package instead of the more usual
linux-image-generic. I installed linux-image-generic and
uninstalled linux-image-virtual, and then the affected domUs would
boot.

I note also that I have some domUs with Ubuntu 12.04.01 using
linux-image-virtual and these are okay. So I assumed whatever
problem there was with that kernel was rectified by the time of the
12.04.01 release.

I hope that helps you.

Thank you very much for your suggestions! â

âAfter Tianyang changed the netboot image used to âboot the domU, the error disappears.Â

So it is likely that the linux-image provided by the ubuntu archive that he uses is kind of broken.Â

It is glad to know that it is not Xen's problem. :-)

âBest regards,â
