vpc 2007 small freezes (hypervisor disabled)
- Hi,
I have Windows 2008 R2 and I made a boot config without the hypervisor driver in order to use Virtual PC 2007 SP1 as indicated by the Virtual PC Guy
http://blogs.msdn.com/virtual_pc_guy/archive/2008/04/14/creating-a-no-hypervisor-boot-entry.aspx
Performance is very good under VPC, but there are tiny freezes every two seconds or so which are, with time, very annoying.
It is as if the VPC would get no CPU for one 10th of second -> choppy feeling. Things other than in VPC are perfect (Games and everthing).
Are there people experiencing this ?
Any solution ?

Tell us more about what's going on in VPC. What OS? Did you install the Virtual Machine Additions? What applications are you running? Do these freezes happen randomly or under load? How much ram is allocated to the vm? What is your disk configuration?
Also, are you certain that you are running the latest bios?Hi,
I am sorry to let you know that we don’t support to install VPC on Windows Server 2008 R2
By the way, according to the description, the issue seems to be related to Virtual PC. As we mainly focus on the Hyper-V question about Windows Server system and here is not the best support resource for Virtual PC, it is recommend you to get further support in the corresponding community so that you can get the most qualified pool of respondents. Thanks for your understanding.
For your convenience, I have list the related link as followed.

Let me explain, I am not asking for support, I am asking if someone has *not* the same issue. If anyone can tell me that VPC 2007 works fine (absolutely no lag) when the hypervisor driver is not loaded then I'll try investigate this myself.
I do have the need to manipulate VPC from my Windows 2008 R2 that has Hyper-V installed, I know it may not be supported. I would spare me create another boot partition just to launch vpc. VPC guy (Ben) has done it on his hyperv system, I need to do the same, even though I know it is not recommended nor supported, just asking if it works on other's.
My OS : Win 2008 R2 x64.
OS inside VPC are Windows XP and Vista, VM additions installed, Virtually no app running : a single notepad window that i drag across the screen will lag.
Most annoying is when scrolling with the mousewheel, it will respond with lag.
I tried to play a video and it was clear that it was regularly lagging. there no load on my machine nor inside the vpc. 1,5 Gb of RAM for the VPC (4 on my machine)
My disk is a 120 Gb SDD Vertex which simply makes wonders in hyperv and in general.
Regarding the bios, my pc is up to date.
I wonder if this is due to the video driver inside the vpc.
thanks for your answers by the way.My approach to having access to Virtual PC 2007 on my Hyper-V server is to use a vm. I have Virtual PC installed inside a vm running on Hyper-V. If I need Virtual PC, I just start the vm that contains it.
Hello John, very interesting, I found the blog post describing this.My approach to having access to Virtual PC 2007 on my Hyper-V server is to use a vm. I have Virtual PC installed inside a vm running on Hyper-V. If I need Virtual PC, I just start the vm that contains it.
You're just loosing hardware virtualization for the VPC VM by doing this. Anyway this is definitely an option for me because if I need serious working on a VM I'd move it into Hyper-V, I'll definitely test this !
(but still wondering if there is a way to fully use VPC by disabling the hypervisor)
