I'm not sure that the vendor string is passed correctly.
Please verify that when starting the guest on an Intel host, /proc/cpuinfo

Currently if VIRTIO_RING_F_INDIRECT_DESC is enabled we will use indirect
descriptors even if we have plenty of space in the ring. This means that
we take a performance hit at all times due to the overhead of creating
indirect descriptors.
Instead, use it only after we're below a configurable offse
Currently if VIRTIO_RING_F_INDIRECT_DESC is enabled we will
use indirect descriptors and allocate them using a simple
kmalloc().
This patch adds a cache which will allow indirect buffers under
a configurable size to be allocated from that cache instead.

Hi
Please send in any agenda items you are interested in covering.
Anthony suggested for last week:
- multithreading vhost (and general vhost improvements)
I suggest:
- status of migration: post-copy, IDL, XBRLE, huge memory, ...
Will send an email with an status before tomorrow call.
Thanks

Thanks, Jan
I changed the URL in .git/config and 'git submodule update --init'
worked and populated the ./linux directory. Then, I ran
./configure
make sync
make
but I got a build error:
$ make
make -C /lib/modules/2.6.32-71.el6.x86_64/build M=`pwd` \
LINUXINCLUDE="-I`pwd`/include -Iinclude
