Thisįeature controls whether DEA wrapping keys will be created to allowĮxecution of DEA cryptographic functions. dea-key-wrap=on|off Enables or disables DEA key wrapping support on s390-ccw hosts. Thisįeature controls whether AES wrapping keys will be created to allowĮxecution of AES cryptographic functions. aes-key-wrap=on|off Enables or disables AES key wrapping support on s390-ccw hosts. The host, de-duplicates identical memory pages among VMs instances mem-merge=on|off Enables or disables memory merge support. dump-guest-core=on|off Include guest memory in a core dump. For accel=xen the default is off otherwise theĭefault is on. vmport=on|off|auto Enables emulation of VMWare IO port, for vmmouse etc. Next one is used if the previous one fails to initialize. If there is more than one accelerator specified, the Depending on the targetĪrchitecture, kvm, xen, hax, hvf, whpx or tcg can be available. So QEMU must be told to not have parallel ports to have working GUS.Īccel=accels1] This is used to enable an accelerator. Note that, by default, GUS shares IRQ(7) with parallel ports and QEMU uses YM3812 emulation by Tatsuyuki Satoh.
