Blktap userspace utils
Hi,
I''d like to use the blktap utils from https://github.com/xen-org/blktap because of the mirror feature, as the blktap utils comming with xen does not support this.
Could anybody explain why there are two different blktap utils (one in git and one comming with xen source) and how to compile the one from git so that it works with libxl ?
Any pointers greatly appreciated ;-)
Thanks

[PATCH 0 of 7 v5] Introduce the tapback daemon (most of blkback in user-space)
This patch series introduces the tapback daemon, the user space daemon that
acts as a device''s back-end, essentially most of blkback in user space. The
daemon is responsible for coordinating the front-end and tapdisk. It creates
tapdisk process as needed, instructs them to connect to/disconnect from the
shared ring, and manages the state of the back-end.
The shared ring between the

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

BLKTAPCTRL[2375]: blktapctrl_linux.c:86: blktap0 open failed
I''m getting this message (subject line) in daemon.log every time I

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

why are qemu-img and vhd-util created files incompatible?
I was wondering if someone can shed some light on why vhd files
created with qemu-img don''t really work right with vhd-util and
consequentially blktap in general. To validate the incompatiblity its
simple enough to do
qemu-img create -f vpc test.vhd 40g
vhd-util snapshot -n child.vhd -p test.vhd
Which will show the below and then the headers don''t display the BATMAP summary:

cannot boot guest VM
Hi,
I''m trying to boot a PV VM I just installed (following http://wiki.xen.org/wiki/Debian_Guest_Installation_Using_Debian_Installer) without success.
My XEN installation is xen-unstable 54c8c9eaee92+ on a Debian unstable machine (x86_64), kernel 3.3.4+. The VM I installed is, again, a Debian unstable x86_64. The installation went smoothly; I used an 8GB file as a disk back-end. I went

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,

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

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

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass
request descriptors to tapdisk, as well as responses from tapdisk to the
front-end. Requests from this ring end up in tapdisk''s standard request queue.
When the tapback daemon detects that the front-end tries to connect to the
back-end, it spawns a tapdisk and tells it to connect to the shared ring. The

no kernel-debuginfo or source RPM for kernel 3.18.21-17

I'm trying to set up systemtap on kernel 3.18.21-17.el6.x86_64 (Xen

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
