Is It Possible To Specify Location of The Huge VMEM Files?

[Dryne]

I recently upgraded the RAM of my workstation to 128GB.  With the increase of memory, I created a RAM drive.  What I would like to do is move the vmem files that get created for all my virtual machines to my RAM drive.  The RAM drive is currently drive Z:.  I took a look at the vmx and vmxf files for my virtual machines but did not see that the vmem files are specified in it.

Is this something that I can do?

I am not aware of a parameter to assign a location for the vmem-files.
However you could try to work without vmem-files.
You could either set
mainmem.useNamedFile = "false"
in the vmx-file - or if you want to set it globally for all VMs put that in the config.ini

This setting will spoeed up the VMs during normal use - but it will also slow down suspends and resume-actions.

I would suggest to work without the vmem file. With older vmware products it was possible with the vmx-setting:

mainMem.useNamedFile = "false"

In newer versions or linux hosts this was replaced by

mainmem.backing = "swap|named|unnamed"

"swap" only works on 64bit hosts,  "named" uses mem file in VM-directory,  "unnamed" uses mem file in /tmp

Hi Dayworker
On Windowshosts it is still the same parameter as in older versions.
mainmem.backing is only used in Linux

Thanks so much for the advice.  After making this change, I noticed an immediate boost in performance of all my VMs.  VMware is now using more physical memory instead of disk for every VM.  I modified the config.ini file with this change so that all my VMs gain this performance boost.
