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

[PATCH] vhd-util create: add -C|nocow option
Add ''-C'' (nocow) option to vhd-util create.
Btrfs has terrible performance when hosting VM images, even more when the guest
in those VM are also using btrfs as file system. One way to mitigate this bad
performance is to turn off COW attributes on VM files (since having copy on
write for this kind of data is not useful). According to ''chattr'' manpage, NOCOW

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

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:

dd if=/dev/zero of=myraw.img bs=1M seek=8K count=1
#Before the command below I install the operating system in myraw.img

blktap2 and qcow2 images
Hi There,
I''ve been trying to get this to work for the last couple of days, but found
no information on the internet that would help. Essentially, a tap-ctl
opencommand with a qcow2 image does not work (error code 2) and
produces the
following line in syslog:

I have attached a shell script that reproduces the problem on my machine.

snapshots on xen
Hi all. I''m using sles11 for my xen servers. I would really like to be
able to do hot snapshots of disk AND memory, and then have these
snapshots backed up to tape or off site for disaster recovery. I''m
thinking this would be done weekly or monthly, not nightly.
Two questions:
1) Is this even possible?
2) I could probably have the systems shutdown to make a clean backups,

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

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:

Time for 4.2.0 rc0?
Hey Keir,
I committed the last of the big outstanding tools blockers for 4.2
yesterday. Currently they are still in staging because they added some
new xenstore paths which tickled the leak detector in the test system
What do you think of doing an rc0 release next week?
There''s still some smaller issues remaining but I think they can wait
until rc1.

How can I take/revert snapshot of a VHD image
Hi there,
I''m running several VMs within Xen, and now I''m trying to create/revert
snapshots of my VMs.
Along with Xen and blktap2, another utility, vhd-util is also delivered,
and according to its description, i guess I can use it to create/revert
VM snapshots.
To create a snapshot is actually easy, I just call
|vhd-util snapshot -n aSnapShot.vhd -p theVMtoBackup.vhd
