Virtual Block Device: frame_and_sects in blkif_request_t
Could someone explain the frame_and_sects field of blkif_request_t(on
2.0.7) for me. From what I make out from the bsd and linux drivers,
these entries specify a machine frame and the section of the machine
frame to write from/copy to. Where I''m confused is the definition of
the size of these sections. Are they each 512 bytes in size?
Then there is the se...

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass
request descriptors to tapdisk, as well as responses from tapdisk to the
front-end. Requests from this ring end up in tapdisk''s standard request queue.
When the tapback daemon detects that the front-end tries to connect to the
back-end, it spawns a tapdisk and tells it to connect to the shared ring. The

xenpaging fixes for kernel and hypervisor
Patrick,
there following patches fix xenpaging for me.
Granttable handling is incomplete. If a page is gone, a GNTST_eagain
should be returned to the caller to inidcate the hypercall has to be
retried after a while, until the page is available again.
Please review.

[RFC][PATCH] Use ioemu block drivers through blktap
When I submitted the qcow2 patch for blktap, suggestions came up that
the qemu block drivers should be used also for blktap to eliminate the
current code duplication in ioemu and blktap.
The attached patch adds support for a tap:ioemu pseudo driver. Devices
using this driver won''t use tapdisk (containing the code duplication)
any more, but will connect to the qemu-dm of the domain. In

Paravirtualised drivers for fully virtualised domains
(The list appears to have eaten my previous attempt to send this.
Apologies if you receive multiple copies.)
The attached patches allow you to use paravirtualised network and
block interfaces from fully virtualised domains, based on Intel''s
patches from a few months ago. These are significantly faster than
the equivalent ioemu devices, sometimes by more than an order of
magnitude.

[PATCH 00 of 17] Documentation updates
The following series flushes my documentation queue and replaces
previous postings of those patches.
The main difference is that the xl cfg file is now formatted using POD
instead of markdown and presented as a manpage.
I have setup a cron job to build docs/html and publish it at
http://xenbits.xen.org/docs/unstable/ (it''s a bit bare right now).
The motivation for some of these patches
