I have Vista 64 bit as os on my machine , and have virtual pc 2007 64 for
virtual app
can I load windows 7 64 bit as a vertual machine ?
When I try it erros adn says the vm is not 64 bit as required by the windows
7 64 os I am trying to load.

No, Virtual PC only supports 32-bit guests. (even the 64-bit version
-- that is so it can run on a 64-bit hosts)

Thurlowe:

Virtual PC does not support 64-bit guests. You can load Windows 7 32-bit, but
some people (myself included) have had very sluggish results (the Virtual PC
Additions are not yet optimized for Windows 7).

I have Windows 7 32-bit working well on VMWare Workstation (you could use
Windows 7 64-bit there if you wanted).

It somehow seems wrong to me that Windows 7 runs better on VMWare than on
Microsoft's own virtualization technology. In fact it seems to me that Microsoft
should be offering pre-release versions of Windows 7 as a virtual machine image
that they had made sure worked reliably in Virtual PC.

Virtual PC guests only run on one CPU core.

So?

I have not done it personally, but I understand that Vista 32-bit has acceptable
performance under VPC, so Windows 7 should also.

Also, I do not believe that VMWare Workstation gives dual core functionality to
the guest. Certainly, my VMWare installation of Windows 7 is not using dual
cores (according to its Task Manager), even though the host is Athlon64 X2 (dual
core).

I haven't noticed the slowness of Win7 in a VM, but I haven't run it
all that much in a VM. (I run it on real hardware)

I expect by RTM there will be, at the very least, new additions.

A VMWare Workstation VM can indeed be assigned 2 cores, and it does
help the performance -- it's not quite a smooth as on real hardware,
but it's there. The default is one core.

Robert:

When we discussed this before, some folks said Windows 7 worked OK in VPC, and
others not. For me, it was totally unusable. The Vista Additions worked, but did
not give the dramatic increase in performance that one often sees.

How does one get dual core operation in VMWare Workstation guest? Do you need
hardware virtualization? My Athlon64 X2 4200+ does not allow hardware
virtualization on my motherboard (Asus A8N-E, Socket 939).

Even with single core, Windows 7 works quite well in Workstation, though there
are some graphical effects that do not seem to work the way I see them
described. If I have time I will dual boot to Windows 7 x64 on my real hardware.
I have BootIt NG all set up to do it; in fact I have Vista x64 installed as a
multi-boot alternative, but I almost never use it).

I don't really know the requirements -- I wouldn't think you'd need
VT, but it's possible. It's just an option in the VM settings for me.
The machine I have it installed on does have VT. (Intel Q6600
processor)

I haven't run Win7 in a VMWare VM so I don't know about performance or
graphics problems. I've seen graphics problems on real hardware
though... (Build 7000) I only use VMWare for Linux.

Windows 7 is not Windows Vista.....obviously. They are different
operating systems running under a VM environment. It's also possible
that the VPC additions are not optimized for Windows 7.

Yes, evidently. I said as much in my previous post in this thread..

I just find it ironic that Windows 7 runs so much better on VMWare Workstation
than on VPC, at least on my machine.
