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

xen 4.1.1 + 3.0.0-rc5 dom0 + blktap2
Hi,
I''m currently trying xen 4.1.1 with the 3.0.0-rc5 (heard that it now
contains the xen code to run as front or back xen domain).
Everything seems to run fine, except that I am trying since a few hours
to mount a .vhd file in the dom0.
What I tried so far:
to create a blank vhd file (this is working):
host# vhd-util create -n /storage/test.vhd -s 20G
Then i try to mount the file

Hi,
Ive just tried Xen 4.0 on Gentoo with 2.6.32 (also tried 2.6.31)

want to write a difference copy program to sync two VHDs in blktap
Hello List,
I''m using blktap on XCP 1.1 and developing a difference copy program for
easy backup and remote archival.
The idea is to read the BAT of VHD1 and sync it to BAT of VHD2 with BITMAP
and the data blocks.
Other way would be by adding a sha1 signature in each data block and
comparing it with remote VHD.
I tried to get some info from below programs but could not get required

produces the
following line in syslog:

a problem with using qcow2 format image files as virtual disks
Hi,
In most cases we use image files as virtual disks under the full-virtualization situation.On the version 4.1.2 of xen,I do the following command:

#Before the command below I install the operating system in myraw.img

Mounting filesystems with blktap2
For those wanting to know how to mount filesystems through blktap2
here is how you do it, as I couldn''t find it fully documented.
The instructions on the blktap2 readme file are rather out of date.
You can mount them under Dom0 like so.
e.g. to mount a vhd file,
sudo xm block-attach 0 tap2:vhd:/home/xen/xenwin7-persist.vhd xvdb w 0
Now the device should appear under /dev
