Ballooning How it works:

Increasing the size of the balloon forces the guest to react to memory pressure by releas

Decreasing the size makes more memory available to the guest

How it works:

Eliminate redundant copies of memory pages common to more thmachine

Hash all memory and store it in a table

Identify the common hashes and then

Perform a bit by bit comparison

Problems Page Sharing not dynamic

Can take hours to share pages

The largest benefit are zero pages
