[PATCH] Shadow mode stats in domain structure are not correct
...ture maintains several shadow mode stats,
such as shadow page counts for l1 & l2, hl2 tables, snapshots,
etc. These counts are not decremented properly when we
free shadow pages. The following patch fixes this problem.
Any comments, suggestions, etc. are welcome. Thanks.

Unindent ERB output
Hi all,
I''d like to unindent a block of ERB specifically to combat the extra
spacing being added to content inside <textarea> by the browser. Is
there such a feature in ERB?
I shall denote indentation with underscores in the pseudo code example
below.
Thanks in advance,
Khoan.

[PATCH v3] virtio_blk: unlock vblk->lock during kick
...U is doing virtqueue kick and another CPU touches the
vblk->lock it will have to spin until virtqueue kick completes.
This patch reduces system% CPU utilization in SMP guests that are
running multithreaded I/O-bound workloads. The improvements are small
but show as iops and SMP are increased.
Khoa Huynh <khoa at us.ibm.com> provided initial performance data that
indicates this optimization is worthwhile at high iops.
Asias He <asias at redhat.com> reports the following fio results:
Host: Linux 3.4.0+ #302 SMP x86_64 GNU/Linux
Guest: same as host kernel

[PATCH] Fix maximum instruction length and minor code clean-up
...immediate bytes).
This patch adjusts the MAX_INST_LEN to the correct
value. This should reduce the size of some variables
in the hypervisor code. This patch also does some
minor code clean-up in the vm exit handler for VMX.
This patch should apply cleanly to hg tip 9594.
Thanks.

Very poor VMX performance
After several days of problems, I finally got Xen 3.0.1 set up in Ubuntu
Breezy with the 2.6.12 kernel on a VT-enabled system with an Intel 930
processor and 2GB of memory.
I have been able to install an unmodified guest without any issues other
than performance. The guest runs extremely slowly and the mouse and keyboard
are all but useless because of the extreme lag. I''ve tried multiple
