Hmm, I suspect the workaround never worked then (it was only a theory).

That was the right thing to do for the install phase.

Hrm. I assume /tmp/vmlinuz exists and is readable by the relevant user
etc. Do the logs in /var/log/xen tell you anything?
BTW, it jut occurred to me that if you install a Squeeze VM onto a Lenny
host that you will find pygrub doesn't work because the version in Lenny
didn't yet understand the grub2 cfg file format. I think d-i still
allows you to select grub1 if you use expert mode, and it looks like you
might be able to add "grub-installer/grub2_instead_of_grub_legacy=false"
to your command line or "d-i grub-installer/grub2_instead_of_grub_legacy
boolean false" to your preseed if you have one.

He's like a function -- he returns a value, in the form of his opinion.
It's up to you to cast it into a void or not.
