[Qemu-devel] Swap disks virtualization

[Christopher Pereira]

We are currently providing Linux swap disks with QEMU driver, virtio bus 
and qcow2 type.

Do you know any alternatives that provide better performance?

Considering that swap disks contain less critical data, QEMU could avoid 
disk IOs by using unassigned memory whenever possible. This could also 
be handled by the underlying linux filesystem of course. Can we tell 
QEMU to use the linux swap disk for creating a guest swap disk? What's 
the state of the art regarding swap disks virtualization?

Best regards,
