The Qemu backend of Tashi
The Qemu backend allows the use of Qemu, Kqemu, and KVM as virtual machine managers. KVM is of particular interest since it utilizes Intel VT and AMD-V technologies, which greatly accelerate the performance of virtual machines.
The vmmSpecificCall options for Qemu are listed below:
- startVnc This option starts a VNC server that exposes the guest and returns a host:port pair that a user can connect to
- stopVnc This stops the above mentioned VNC server
- changeCdrom:<target> This replaces the virtual cdrom drive in a guest with another ISO
- startConsole This opens a TCP port that a user can telnet to to get direct access to the Qemu control console
- list This lists the options available on this particular version of the Qemu backend
Additionally, the following hints are useful with the Qemu backend:
- clock This specifies the clock type to use for the VM -- options are "dynticks", "rtc", etc.
- diskInterface This specifies the disk interface to use for the VM -- options are "ide", "scsi", "virtio", etc.
- nicModel This specifies the NIC model to use on the VM -- options are "e1000", "rtl8139", "virtio", etc.
- noAcpi This is a boolean that specifies whether or not ACPI is emulated
