[libvirt-users] IDE vs SATA vs VirtIO

[William Kern]

ok from googling its clear that VirtIO is consistently recommend for the 
best performance.

However, with some legacy VMs that we are bringing into the system isn't 
an option.

Is there a peformance difference between IDE and SATA?

For that matter how much BETTER is VirtIO over the other two?

Note, these are QCOW2 images if that makes a difference.
