COLO PVM and SVM's memory usages

[Jing-Wei Su]

Hello,

I've found the SVM consumes lots of memory than expected.
After booting the PVM and SVM with "-m 1024", PVM consumes 1GB, but
SVM consumes 3.2GB.
After PVM died and SVM takes over, the SVM consumes 2.1GB.

Any idea about why the SVM consumes lots of memory?
Thanks!
