Vista - Super Slow Performance in VPC - 6mhz?

Hi all-

I decided to install windows 7 beta on a vpc to play with it after seeing
others do it but the performance is incredibly slow. The VPC is installed on
on a AMD Turion 64 x2 tl-58 1.90ghz processor and 4gb of ram. I gave the VPC
1.5gb of ram and 30 gigs of hard drive. The Windows 7 install took about 12
hours to complete! Start up is fast but even moving the mouse around is
choppy and open the start menu takes at least 5 seconds. When I go into the
control panel 7 says I have 1.5gbs of ram but that the processor speed is
"AMD Turion 64 X2 Mobile Technology TL-58 6MHz. How do I give more of the
processor to the VPC? I have the latest version of VPC with SP1 and
installed windows 7 as "other" How do I increase the processor clock?
THANKS!

You need to install the VPC additions. Setting your laptops power
settings to maximum performance will help too.

Mr. Comer,

Power settings are already on maximum and its plugged in as well. How do I
install the VPC additions? Do you happen to know why additions fixes the
problem? What's holding the performance down so much?
When I click on actions -> install additions it says it will run it as a cd
but nothing happens when I click ok.

Thanks!

of the VM and select "Install or update Virtual Machine Additions."
Just wait for it to autostart and follow the prompts.
It's not that it "fixes" anything, but it install drivers and teaks
some settings to make it so the OS in the VM works with the
virtualization software better.
Drivers not optimized for the job of running in a VM and way to many
kernel mode transitions. (kernel mode transitions are very expensive
time-wise in a VM.
Give it time, it sounds like it's just extremely slow.

You might back the RAM down to 1G, I don't think the extra is helping
you any, at least until you get the additions installed.

It was just extremely slow and evenchaully started the installation which
just completed. After the reboot the system is just as slow. It takes
almost ten minutes boot. I cannot remember ever using a computer this slow,
if it wasn't running in VM I would think that the computer was frozen. I
have a cpu utilization gadget running on the host OS (Vista Ultimate) which
never goes past 50% so there is plenty of untapped utilization. Control
panel in 7 now shows 1gb ram but now says "14046291MHZ" haha not sure what
that means.... Any other ideas I can do to get VPC to utilize the processor?
I'm doubting that it is a problem with Windows 7 since the installation took
so long.

I haven't got the sound working yet but see that it is a common problem but
perhaps it is useful in diagnosing the problem? I havent fixed it yet
because its too slow to do anything with.

So do the VM have a virtual kernel or does it access the system kernel?

Thanks for your help!

The slowness isn't normal, but 50% utilization is, VPC only uses one
core and your machine is dual core, so the max that one core can be
used is 50% of the system.
You might try this:

http://blogs.msdn.com/virtual_pc_guy...n-laptops.aspx

Read the whole page.
It has to use it's own kernel, as does the host OS. The kernel's just
the base part of the OS. Kernel mode is kind of like an interrupt
level, when in kernel mode, nothing else can interrupt the task, but
user mode, interrupts run normally.
No problem, I hope we can get it going faster for you, 10 minute boot
times is not the norm.

Yes I have VPS 07 SP1, good call on the single core, completely forgot about
that. I will try the solution posted at msdn and let you know how it works.
Thanks!

I know 10 minutes isn't normal! I have several friends running 7 in VPC,
some with only 512 ram and its lightning fast, very impressive!

Updated the appdata, saved, restarted pc (just for fun) and tried launching
VPC again, sadly it is still incredibly slow. Control panel says I am up to
96mhz but boot still takes as much as ten minutes. Debating bailing on this
project and trying it on another pc unless anyone has any other ideas.

Thanks.

A BIOS update on your laptop is about the last thing I can suggest.

BIG mistake! You should have selected "Vista" as the type!
Do as follows:

1) Shut down the guest completely
2) Delete its VMC file (keep the VHD)
3) From the VPC2007 console create a new guest and this time select
Vista as the type
4) When you come to the hard disk, choose existing and browse to your
VHD file
5) Start up the guest again and then from the action menu install the
Virtual Machine Additions
6) Make sure that all host system power settings etc are set for full
speed (no throttling)
