[Xen-devel] [PATCH] HVM Debug Console Support (v2)

[Owen Smith <owen.smith@xxxxxxxxxx>]

HVM debug console support for PV drivers

This patch creates a shared ring buffer and event channel in HVM domains

that the Windows PV drivers can use to send debug output.

Modifies the HVM domain builder code to add a shared memory page for the

ring buffer.

Modifies the Save/Restore code to store the shared page mfn during save/restore

Note: VMs saved on this patch will not restore prior to this patch. VMs saved prior

to this patch will restore on this patch, without the shared console ring.
