The vmmouse driver is used to have a "transparent" mouse between the
virtual machine and the desktop. ie: no need to press ctrl-alt to
release the mouse.

vmmouse worked automatically in jaunty, but was broken in Karmic. The
patch in 1:12.6.5-2ubuntu3 makes it get detected in Lucid again, and
enabled automatically.

Yes, the vmmouse driver is more CPU intensive than the regular mouse
emulation. Moving the mouse around rapidly in circles in a Lucid VM on
my machine results in 20-30% cpu usage. Under normal mouse usage, it
doesn't use that much.

How much CPU usage are you experiencing?
