Do you have a particular test pattern in mind? If there is nothing going on
in the VM XBZRLE will not be better than normal copy at all.
Otherwise you will have N xbzrle misses and 0 xbzrle pages without the
patch
and 0 xbzrle misses and 0 xbzrle pages with the patch.
How about a migration of a guest running the synthetic r/w load
generator in docs/xbzrle.txt?
Good idea. I will leave max downtime and bandwidth at default values.
Would you be happy with 1GB vRAM and 256MB page cache?
