I face the problem of having vmware disks files (vmdk) on ntfs partition (for sharing them between windows and linux installations).
When I run vmware with this configuration in linux I get an hight CPU usage by ntfs.mount process. Many blogs says that adding mainMem.useNamedFile=FALSE to virtual machine configuration file will fix this issue.
This probably worked only with older vmware versions.
Then I found this.
It says to change the location for snapshot and suspend files to a non ntfs partition. This just works!!
