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 | But when it comes to reverting a snapshot, things get really annoying The &...

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 d...

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). Accordi...

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 in dom0 (as stated in a blktap2 README file) host# tapdisk2 -n vhc:/storage/test.vhd it fails, returning: tapdisk2: invalid option...

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 VNC console for the Windows HVM has this message: Booting from Hard Disk ... Boot from Hard Disk fai...

...ow it would be a lot easier and reliable just to to one convert one time and start to generate real vm snapshots, but at this time I cannot use this method. I tested the sequence: disk2vdh -> xenconvert (to xcp), but a big deal of using this method is that xenconvert does not send only the .vhd file through the network, but all the disk size whose partition was converted. So, if my win2003 has a physical HD of 250GB and C: is on first partition of 10GB, the generated .vhd will have ~10GB, but xenconvert sends 250 GB via network to xcp server. Well, with my scenario I cannot rely on t...

...Cloud Platform (XCP) is an open source enterprise-ready server virtualization and cloud computing platform, delivering the Xen Hypervisor with support for a range of guest operating systems. This package is part of it. It implements the userland part of the blktap driver. . Virtual Hard Disk (VHD) is a file format standard which maps logical hard disk contents to a physical disk image format, which can then be more efficiently stored in a variety of different storage types, such as file systems or logical volumes. . VHDs are container files storing block metadata alongside a virtual di...

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 info about adding a sha1 sign of data block while writing it. Simi...

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: tap-ctl: tap-err:tap_ctl_open: open failed, err -2 I have attached a shell script that reproduces the problem on my machine.
