Notes
[wheezy] - xen <not-affected> (Vulnerable code not present in the bundled 0.10 qemu)
[squeeze] - xen <end-of-life> (Unsupported in squeeze-lts)
[squeeze] - xen-qemu-dm-4.0 <end-of-life> (Unsupported in squeeze-lts)
Qemu only exploitable by privileged administrator with malicious configuration
Xen in Squeeze uses a separate source package: xen-qemu-dm-4.0
Xen in Wheezy includes qemu
Xen after Wheezy uses qemu-system-x86 from qemu, marking 4.2 as pseudo fixed
