"OS information"Is necessary to fill field "Name" and if you want you can change default path to VM.Fields "OS type" and "OS version" don't use now. It removes entries such as SSH host keys, log files, user accounts, and some persistent network configurations. The definitions exposed by libvirt could be completely different from the definitions in QEMU, as long as libvirt probes for CPU model information and uses the right flags in the command-line to make QEMU expose what libvirt users expect. First create the Virtual hard disk image for the new VM. thufir@dur:~$ The keyboard shortcuts CTRL-ALT-{1,2,3} can be used inside the emulator to swap in/out of the emulation screen, the QEMU console and a serial console.
