Hi Mark,
Thanks for your reply.
I am aware of this issue and I compiled kernel following exactly instructions
here:http://wiki.xensource.com/xenwiki/XenParavirtOps
So the kernel is
(source=git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git, branch=xen/stable-2.6.32.x)
with the CONFIG_* enabled as per the above wiki, plus
CONFIG_XEN_BLKDEV_TAP=y
CONFIG_XEN_BLKDEV_TAP2=y,although the CONFIG_XEN_BLKDEV_TAP2=y line got
stripped out during the 'make' process.
I can see /dev/blktap-control, /dev/xen/blktap-2/control exist.

do you start your VM with xm or xl? If you use xm, are services configured
close to this?

Hi,
I am running XEN 4.1 on Debian 6 and I cannot find blktapctrl process running.
xend is started. I installed XEN from 4.1 source following instructions
here:http://wiki.xensource.com/xenwiki/XenParavirtOps
http://wiki.xensource.com/xenwiki/Xen4.0
Should there be a blktapctrl process running in this version?
The problem I have encountered is that I can create a domain on a raw disk
image but not on a QCOW disk backed by a base image. XENBUS timed out during
the DomU boot process so I figured it was trying to communicate with blktapctrl
process on Dom0 but couldn't find it.
Thanks,Jiangyan

blktap
tapdisk
tapdisk2
blktapctrl
the above are disabled in the linux-image-2.6.32-5-xen-* Debian kernels by
design. The reason ultimately resolves to the problems with Openssl as seen by
the Debian developers.
If there is a reason to use all custom build, this is it.
