Hi, Attached patch adds a 'vmware' machine type. This one automatically uses VMware display card, and enables VMware mouse. In non VMware machine types (ie 'pc' and 'isapc' types), VMware backdoor and VMware mouse are disabled [1] I added an enum with PC types in pc.c . This system can be extended later to add more PC types. Please comment. Hervé [1] This has the same effect that the switch '-no-vmport' proposed by Ian Kirk in http://marc.info/?l=qemu-devel&m=121957847306185&w=2
