We recently ran into issues with intermitten performance on a Microsoft Virtual Server 2005 R2 Enterprise Edition deployment after SP1 was applied. Basically, the system was freezing up for several seconds up to a few minutes.
The issue was resolved by updating the Virtual Machine Additions. After researching the issue we found that VMAdditions on the guest server was not the same version as on the host server. It took two reboots of the guest server but we got it upgraded and the performance not only the affected guest server improved but the performance of all virtual machines imporved on the host server.
Recommendations for troublshooting performance on Virtual Server 2005 R2 SP1:
- Check the VMAdditions Versions on all virtual machines and make sure they are the same as the host server. This can have the largest impact on performance for all guest virtual machines.
- Ensure that you are running your guest virtual machines from a seperate physical hard drive and/or controller/channel for best performance.
- Make sure not to run other services from the host sever. This will impact the processor slicing and availability.
- Ensure you have allocated enough memory to the guest virtual machine. Unfortunately, Virtual Server 2005 is not the best at Disk IO so minimizing swap file hits can make a huge difference.
- On occasssion, stop the guest virtual machine and defragement the host virtual machine hard drive.
Hope these are useful. If you still have problems let us know. We will gladly help. |
