This feature, when supported by the host, de-duplicates identical memory pages among VMs instances (enabled by default). mem-merge=on|offĮnables or disables memory merge support. For accel=xen the default is off otherwise the default is on. auto says to select the value based on accel. vmport=on|off|autoĮnables emulation of VMWare IO port, for vmmouse etc. If there is more than one accelerator specified, the next one is used if the previous one fails to initialize. Depending on the target architecture, kvm, xen, hax, hvf, nvmm, whpx or tcg can be available. Supported machine properties are: accel=accels1] To allow users live migrating VMs to skip multiple intermediate releases when upgrading, new releases of QEMU will support machine types from many previous versions. To allow live migration of guests from QEMU version 2.8.0, to QEMU version 2.9.0, the 2.9.0 version must support the "pc-i440fx-2.8" and "pc-q35-2.8" machines too. For example, the 2.8.0 release introduced machine types "pc-i440fx-2.8" and "pc-q35-2.8" for the x86_64/i686 architectures. Use -machine help to list available machines.įor architectures which aim to support live migration compatibility across releases, each release will introduce a new versioned machine type.

QEMU uses GUS emulation (GUSEMU32 ) by Tibor "TS" Schütz. QEMU uses YM3812 emulation by Tatsuyuki Satoh. QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL VGA BIOS. ![]() PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1 hub.Adlib (OPL2) - Yamaha YM3812 compatible chip.Intel HD Audio Controller and HDA codec.Intel 82801AA AC97 Audio compatible sound card. ![]()
