[Qemu-devel] [PATCH 0/2] fw_cfg: Implement fast "blit" operation for rap

Subject: [Qemu-devel] [PATCH 0/2] fw_cfg: Implement fast "blit" operation for rapidly copying in kernel, initrd [etc] into the guest

User-agent: Mutt/1.5.18 (2008-05-17)

These two patches implement a faster way to copy the kernel and initrd
data into the guest.  The guest can set up a blit address and then
issue a blit command in order to tell qemu to copy the whole of the
configuration data into the predefined area of memory.

This saves a couple of seconds of boot time when you have very large
initrd images.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.
