VMware Guest VM On An NTFS Partition Mounted With NTFS-3G June 13, 2009

Well folks the saga continues. After monitoring the CPU usage of the Host machine using the “top” command, by chance I saw that a process called mount.ntfs-3g was using a large amount of the CPU when I started a Guest VM. This guest VM is on a NTFS partition mounted with ntfs-3g. I did a little research and found that this is something that is also mentioned on the ntfs-3g website: http://ntfs-3g.org/support.html#cpu100. I made the required changes to the VM which is putting this in the .vmx file:

mainMem.useNamedFile=FALSE

After making this change and starting up the Guest VM once again, the process mount.ntfs-3g was not using as much of the CPU as before.

After running this test, I decided to upgrade to the latest stable version of ntfs-3g that was available on the website. The version that I was running was version 1.2531. I updated to version 2009.4.4

I can honestly say after making these changes and installing the updated version of ntfs-3g, the performance of the Guest VM has increased.
