RedHat ES4 as vm client

Tammy Liang — Tue, 30 Jan 2007 14:05:27 GMT

I have vm guest running RedHat ES4 with 1 G RAM and 2G swap. I see memory usage from top, both of physical and swap are used.
However, when I look at memory performance for the redhat guest from virtual center, swap usage is always 0, even physical used up to 97%. Why does virtual center shows swap 0% used?

Thanks for any reply.

The VC is running on Windows Server 2003.
I am running Virtual Infrastructure Client Version 2.0.1 Build 32042 on my XP.

Thanks.

Shalom,

Possible ideas:

Guest system is using no swap.

Bigger Windows system is not needing to use swap.

The information in the vmcenter is wrong.

Another idea.

To ideas in Linux

swap use, which means processes are being moved in and out of ram to disk and swap reservation which means swap is being reserved but not used.

Its very common for the OS to use 100% of memory. Its often used as a disk or memory buffer cache.
