VMplayer: Silencing excessive hard disk activity

For some unknown reason, possibly after an VMplayer upgrade, running any Windows Virtual machine on my Linux machine with WMware Player caused some non-stop heavy hard disk activity, even when the guest machine was effectively idle, and made had no I/O activity of its own.

Except for being surprisingly annoying, it also made the mouse pointer non-responsive and the effect was adverse on the hosting machine as well.

So eventually I managed to get things normal by editing the virtual machine’s  .vmx file as described below.

I have Vmplayer 6.0.2 on Fedora 12 (suppose both are considered quite old).

Following this post, add

isolation.tools.unity.disable = "TRUE"
unity.allowCompositingInGuest = "FALSE"
unity.enableLaunchMenu = "FALSE"
unity.showBadges = "FALSE"
unity.showBorders = "FALSE"
unity.wasCapable = "FALSE"

(unity.wasCapable was already in the file, so remove it first)

That appeared to help somewhat. But what really gave the punch was also adding

MemTrimRate = "0"
sched.mem.pshare.enable = "FALSE"
MemAllowAutoScaleDown = "FALSE"

Don’t ask me what it means. Your guess is as good as mine.
