Hello,

Here's an update for my previous report.

Newer kernel (maybe 2.6.24, and 2.6.26) reveals a bug in VirtualPC,
where it fails to boot with the error message "An unrecoverable
processor error has been encountered. The virtual machine will reset
now."

This bug only occurs on the installed system (i.e not when booting
debian-installer). An easy work-around is to add "noreplace-paravirt" to
the boot command line.
A patch was applied upstream (for 2.6.27) to solve this problem. see

Some other bugs exists, but they have been reported to DD maintainer or
upstream, then documented on the wiki page:

I'm reassigning the bug to the kernel team since it cannot be dealt by
us.

Humm, interesting ...

Could this be backported? This is a very simple fix and I believe it
is worth a backport. Kernel Team?
