BLKTAPCTRL[2375]: blktapctrl_linux.c:86: blktap0 open failed
I''m getting this message (subject line) in daemon.log every time I
start or restart xend. I''m not sure if this is related to the fact
that I cannot boot up my Windows domU from a VHD file. The Windows
domU was working fine with Xen 4.0.0 (with 2.6.32.14 dom0 kernel).
When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can
no long boot the Windows domU from VHD. The

BLKTAP
I noticed recently that there is no real easy way to get the kernel driver
for blktap working in mainline. I''ve pulled down the source from Daniel
Stodden''s linux git tree on xensource, but it looks like it''s for debian and
I''m running Fedora 14, so I''m trying to sort it out. I run the 3.1.x kernel
and don''t want to go back to the 2.6.32 that

tools: do not link against unused libraries.
A fair few things under tools link against libraries which they don''t
even use.
Most of this appears to come from copy-and-pasting previous Makefile

RFH: loopback & blktap(2) and CDROM
Hello,
I''m currently trying to understand some problems I had in the past with mixing
look-back with blktap(2) for HV and PV domains. I''m stuck reading the source
code, so I''d like to get some help from the list. Interrupt me if I got
something fundamentally wrong in my understanding so far:
1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

Xen 4.0.1, tap vs tap2, blktap2 documentation, and gentoo-xen-kernel problem
Hi,
I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 +
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-4.tar.bz2,
and one of the things that I noticed immediately is there are two
problems with tapdisk and this combination.
First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works.
When tested with HVM domU, it boots, but there was no disk

Using the Xen GPLPV drivers
There seems to be an outdated page to use PV drivers here:
http://wiki.xensource.com/xenwiki/XenWindowsGplPv
I''d be great if that could be updated.
After installing the PV drivers in windows I didn''t notice any difference in
performance at all. Windows says the drivers are working.
Some more searching and reading and it appears that I do actually need to
make some changes to

domU can not start in Xen 4.0.1-rc3-pre using tapdisk
The domU is using pygrub to boot its own 2.6.18.8-xen kernel. It can be
booted successfully under 2.6.18.8-xen dom0 and xen 3.3.1.
However when upgrade dom0 to 2.6.32.15 and xen 4.0.1-rc3-pre, the domU can
not boot with tapdisk. I am wondering it is something related to the blktap
driver.

Memory sharing
Hi,
Currently i''m going through the source codes of tools/blktap2. I need to
find-out where blktap2 calls
1. mem_share_nominate()
2. mem_sharing_share_page() functions to do the memory sharing on HVM
guests.
Can someone please provide me some guidance on blktap2 driver.
Thanks,
Harshan

Xen blktap driver for Ceph RBD : Anybody wants to test ? :p
Hi,
I''ve been working on getting a working blktap driver allowing to
access ceph RBD block devices without relying on the RBD kernel driver
and it finally got to a point where, it works and is testable.
Some of the advantages are:
- Easier to update to newer RBD version
- Allows functionality only available in the userspace RBD library
(write cache, layering, ...)
- Less issue when

blktapctrl not running

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:

Should there be a blktapctrl process running in this version?
