I have tested Xen HVM, HVPVM and PVM guests all with tmem enabled. Automated testing is scheduled to go into our test farm (that runs ~80,000 hours of QA of testing of Oracle products on Oracle Linux per day) soon. > - OracleVM since 2.2 (2009) Likewise. We are planning to incorporate Transcendent Memory support into future Oracle VM 3.0 releases as support functionality, i.e. that this will be enabled on a per-server/per-guest basis so that guests are capable of reducing memory footprint. We see this as a critical feature to compete with other hypervisor's memory sharing/de-duplication functionality.
