Hmz, i'm running multiple windows 2003 servers within virtualbox running on Solaris 10 hosts. Some windows servers are online for almost a year now.
The VHD's are stored on a Zfs mirror and i never had any out-of-memory errors.
The solaris servers also serve glassfish, mysqlcluster and many, many more services from zones.
Running out of memory can imho only be caused by a programmingerror in the virtualbox version.
Zfs will not cause an out-of-memory
