Hi all! I'm trying virt-manager on Debian Wheezy and I noticed that it has already defined a "default" pool. But if I run: # /etc/init.d/libvirt-bin restart I lose the definition of the pools. Actually, there are the definitions of the pools; but these are not read after restarting libvirt. ss01:/etc/libvirt/storage# ls -l total 8 drwxr-xr-x 2 root root 4096 jun 1 09:36

Hello. We have a number of Xen 3.4.2. boxes which have constant iowaits at around 10% with spikes up to 100% when accessing data over NFS. We have been unable to nail down the issue. Any advice?

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

Hi, In view of the problems I was having with DomU network timeout after a live migration (I posted that problems here a while ago but never got anything except from private emails) I finally updated my Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to 2.6.32-26. Now live migration just hangs...Any ideas? Xen-related Debian packages (all from Debian repositary, except drbd

Guys, I'm trying to compile the Xen 4.0.0 via debian/rules makefile but I got this: administrativo at sid01:~/xen/xen-4/xen-4.0.0$ make -f debian/rules build-tools ..... make -C lib all make[7]: Entering directory `/home/administrativo/xen/xen-4/xen-4.0.0/debian/build/build-tools/tools/blktap2/vhd/lib' make[7]: Nothing to be done for `all'. make[7]: Leaving directory

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:

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, I''m now blocked for 2 days on getting the network to work in my domU. Here is the problem : The domU refuses to start when a vif is configured. It''s just staying paused for about 1m40s, then the xm create command line give back with an "Error: Device 0 (vif) could not be connected. Hotplug scripts not working.", and the domU is destroyed. Nothing particular

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

I have try to resize one vhd file with vhd-util, i did some test...

Hi all, I`m evaluating methods for nightly "snapshot" a physical win2003 to xcp vm. I know 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

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
