Hi,

This patch series are updated version of Kemari that we posted last week.

http://lists.xensource.com/archives/html/xen-devel/2009-03/msg00371.html

Thanks for the comments, and we're working to improve and clean up the code
appropriately.  The following patches can be applied to the 3.4 unstable tree.

xen, xend: xen-unstable.hg c/s 19303:b249f3e979a5
linux: linux-2.6.18-xen.hg c/s 817:0430b1dbfb3a
ioemu: qemu-xen-unstable.git c/s 82787c6f689d869ad349df83ec3f58702afe00fe

If you can take a look, it would be very helpful.
Any comments are appreciated.

Thanks,

Yoshi

Overview:

Kemari in VMM taps event channel, pauses the guest (not suspend), prepares for
transfer, and Kemari in userland transfers the guest.  On failover, Kemari on
the secondary restores the guest, and the backend drivers in dom0 set up the
backend rings from the state of the shared rings in the guest.

[05] xend: Kemari sender in libxc
[06] xend: Kemari receiver libxc
[07] xend: add Kemari support to python
[08] xend: add dev state "Attached" to python
[09] linux: add XenbusStateAttached to xenbus
[10] linux: XenbusStateAttached handler for blkback
[11] linux: XenbusStateAttached handler for netback
[12] ioemu: use signal to save qemu state for Kemari
[13] ioemu: use shared region with to flip logdirty_bitmap
