I''m using the CentOS 6 bundle of xen from http://dev.centos.org/centos/6/xen-c6/ and ran into an issue when creating domains with multiple VHD tap disks. Comparing unstable to the 4.2.1 code I''m using, it seems this issue still applies. I''m using a configuration line that looks something like disk = [

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

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

Hi, How can I use "vhd-util" or "vhd-update"? Have someone a manual for this? A tutorial? Any help?

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

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

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

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 The instructions on the blktap2 readme file are rather out of date.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 ls

We had a XCP 1.5 pool with 2 machines as hosts. The storage pool which as NFS mounted lost its ability to export the filesystem with the VM images on it. We contacted the vendor and we were able to restore it. However, they had recommended that we delete the XCP Pool, recreate it, add the hosts back in, and then mount the storage. That is where we are at now. We can see the storage and
