Just a thought - is it trying to load a screensaver / blank screen, but
not actually changing the screen - therefore the moving of the mouse /

Regarding 7.10 regression, I haven't tried gutsy installs with my vm,
but I will and will post back.
As for where it stalls, it is random places. I've seen it stall in
'Scanning for CD-ROM', different packages, pretty much anywhere between
setting up the keyboard and the partitioner. I did see
Jamie, where does it stall for you, if not during the erase stage?
My tests have all been on a Core 2 Duo T7500 and I haven't been able to
reproduce the problem at all despite several test installations using
alternate install CDs.
Is this specific to the server kernel?

For people trying Gutsy or earlier CDs in kvm, you have to update the iso. See:

Stéphane Graber's comment about entropy got me thinking...
Is there anywhere in the installation that depends on entropy

Something like openssh-server would, of course, for key generation. But
that's not a default package, and the installation/configuration
Current thinking is that there are probably two separate issues here:
1. A problem specific to the KVM virtual environment
2. A problem specific to a particular hardware type.

I think we can consider kvm a hardware type for these purposes.
So I think we have found bugs on two hardware types that present the
same way, but may, or may not have the same cause.
We could have two hardware platforms that themselves have identical
