Hello!

I'm a VirtualPC 2004 user who just upgraded to VirtualPC 2007. I also
moved my virtual machines to a different host. Strangely, on the new
host none of my virtual machines boot... at all. Specifically when I
click 'Start' I get a windows for the Virtual machine, but it remains
black. There is no (virtual) BIOS output such as POST results or memory
size. As far as I can see, nothing happens at all.

The virtual machines boot and run fine under VirtualPC 2004 (on my other
host system). I'm wondering if anyone has seen this behavior or has any
thoughts as to what might be causing it. I searched Google and the
VirtualPC help, but I didn't turn up anything that seemed to address my
problem.

The host is a dual core (32 bit Intel processor) Windows XP machine,
fully patched. The host has 2 Gbytes of RAM. The guests are non-Windows
systems, but I don't think that's relevant since they never even start
to boot. I do have undo disks enabled. However, the guest settings are
almost the same as they were on my other host although I did boost the
memory settings to 256 Mbytes since my new host has a lot more RAM (the
guest memory settings were on the order of 128 Mbytes before). Note that
the old host was also a Windows XP system fully patched. It was using a
hyperthreaded processor, but not a dual core one.

The behavior I described is identical for more than one guest system.

I should probably also mention that I have VMware Workstation
5.5.something installed on the same machine. I'm not sure if the two
virtualization packages will interact badly or not. I'm thinking maybe
not since VirtualPC seems pretty well self-contained. At least that's my
hope.

Thanks for any thoughts you might have.

Peter
