To allow execution of DEA cryptographic functions. This feature controls whether DEA wrapping keys will be created dea-key-wrap=on|off Enables or disables DEA key wrapping support on s390-ccw hosts. To allow execution of AES cryptographic functions. This feature controls whether AES wrapping keys will be created aes-key-wrap=on|off Enables or disables AES key wrapping support on s390-ccw hosts. Supported by the host, de-duplicates identical memory pagesĪmong VMs instances (enabled by default). mem-merge=on|off Enables or disables memory merge support. dump-guest-core=on|off Include guest memory in a core dump. vmport=on|off|auto Enables emulation of VMWare IO port, for vmmouse etc. Specified, the next one is used if the previous one fails to Depending on the targetĪrchitecture, kvm, xen, hax, hvf, nvmm, whpx or tcg can be available.īy default, tcg is used. Supported machine properties are: accel=accels1] This is used to enable an accelerator.

QEMU will support machine types from many previous versions. Skip multiple intermediate releases when upgrading, new releases of To allow live migration of guests from QEMU version 2.8.0, to QEMU For example, the 2.8.0 release introduced machine types Use -machine help to listįor architectures which aim to support live migration compatibilityĪcross releases, each release will introduce a new versioned machine Standard options ¶ -h Display help and exit -version Display version information and exit -machine name]
