[Xen-devel] [PATCH 0 of 5] HVM performance improvements

To: <xen-devel@xxxxxxxxxxxxx>

List-id: Xen developer discussion <xen-devel.lists.xen.org>

This patch series contains the results of an investigation by XenServer
to try and reduce dom0 load during a VDI bootstorm.

All patches reduce the number of polled IO traps to qemu that a booting
HVM domain uses.

The patches are unmodified from the last time I posted them to the list,
but are presented now outside of a feature freeze.
