=== How to determine if the host can run virtualization on hardware ===
 
* If the CPU supports hardware virtualization then ensure it is enabled on BIOS
 
# egrep -c '(vmx|svm)' /proc/cpuinfo
 
 
=== How to quick launch an 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 <code>kvm</code> instead <code>qemu-kvm</code> command
 
 
Where
 
* <code>-boot</code> [order=drives][,once=drives][,menu=on|off]
 
: 'drives': floppy (a), hard disk (c), CD-ROM (d), network (n)
 
* <code>-hda/-hdb</code> file use 'file' as IDE hard disk 0/1 image
 
* <code>-cdrom</code> file use 'file' as IDE cdrom image (cdrom is ide1 master)
