High Virtual memory usage, but very low real memory usage, is that normal?

redjersey

I have a vps with the following spec:

6144MB Guaranteed RAM
4 CPU Cores
250MB Virtual Memory

I have virtualmin / webmin installed on it.

I have noticed that my VPS has a very high virtual memory usage for most of the time (between 75-95% usage) but the real memory usage is very low (15-20%)

Is that normal?
