Configuring and Maintaining the Host Computer

Configuring and Maintaining the Host Computer

You may see slower virtual machine performance if the physical disk that holds the virtual machine's working directory or the physical disk that holds the virtual disk files is badly fragmented. By default, the working directory holds the virtual disk files and is on the host computer. If you have customized the virtual machine configuration, you may have placed the working directory or the virtual disk files on a different physical computer.

Fragmentation of the host disk can affect any or all of the following:

  • The files that hold a virtual disk
  • The files that store newly saved data when you have a snapshot
  • The files that hold information used in suspending and resuming a virtual machine

If you are experiencing slow disk performance in the virtual machine, or if you want to improve the speed of suspend and resume operations, check to be sure the host disk that holds the virtual machine's working directory and virtual disk files is not badly fragmented. If it is fragmented, you can improve performance by running a defragmentation utility to reduce fragmentation on that host disk.
