KVM
- If the CPU supports hardware virtualization then ensure it is enabled on BIOS
# egrep -c '(vmx|svm)' /proc/cpuinfo
How to launch a fast instance
Create and empty disk of 1Gb and launch a VM as:
# dd if=/dev/zero of=disk.img bs=1M count=1024 # qemu-kvm -boot d -hda disk.img -cdrom /dev/cdrom
On Ubuntu use `kvm` instead `qemu-kvm` command
Where
- `-boot` [order=drives][,once=drives][,menu=on|off]
'drives': floppy (a), hard disk (c), CD-ROM (d), network (n)
- `-hda/-hdb` file use 'file' as IDE hard disk 0/1 image
- `-cdrom` file use 'file' as IDE cdrom image (cdrom is ide1 master)
