After a 'virsh blockpull', 'virsh snapshot-list --tree' o/p does not reflect reality
Hi (Eric?), A couple of questions while using the 'virsh blockpull' Summary: 1] Created snapshots this way: base<-snap1<-snap2<-snap3 (online, external snapshot --disk-only) 2] I did a 'virsh blockpull' from snap2 into snap3 3] Next, did another 'virsh blockpull' from snap1 into snap3 - Here, 'qemu-img info /path/to/snap3' shows its backing file

Unfortunately, for some reason, I can not shutdown the vm, and exectue the "virsh blockpull" command. Can I execute the "virsh blockpull"

Managing Live Snapshots with Libvirt 1.0.1
Hello, I recently compiled libvirt 1.0.1 and qemu 1.3.0 on Ubuntu 12.04. I have performed live snapshots on VMs using "virsh snapshot-create-as" and then later re-merge the images together using "virsh blockpull". I am wondering how I can do a couple of other operations on the images while the VM is running. For example, VM1 is running from the snap3 image, with the following

Deleting and coalescing live snapshots
All, I have a service that takes new live KVM snapshots Si regularly, keeps a fixed number N (Si ,..,Si-N+1), and therefore needs to delete Si-N in this cycle. Until libvirt includes support for this capability that is said to be available in qemu, what is a safe workflow to delete old live KVM snapshots w/o losing data. Do I need to pause/shut down the VM? The development environment is

Looks like blockpull does not accept a subset of the entire chain of backing files
Hello If I'm not terribly mistaken, looks like libvirt 1.2.1 does not provide ability of merging only a subset of the entire chain of backing files. So, if I have a chain like this: root <- a <-b <- c <- d <- active ... and I'd like to obtain a chain like this: root <- c <- d <- active ... looks like it's not supported,

Questions and a blockpull issue
Coming off of xen environment; still testing with kvm, just a few questions: 1. What is the roadmap for release of qemu-kvm 1.1 and libvirt 0.10.2 for el6, cause I had to compile from upstream to get the latest stuff. 2. Should not virt-manager show the sparsed disk size instead of actual reserved size of a vm? 3. Where is the virsh bash_completion conf.d file from upstream; since el6 rpm

unattended cloning
Morning, I have a KVM guest running Win 2012 with MS SQL 2012. In order to provide a quick method of restoring the service should the live server die, we've decided to clone it to a preserved state. Ideally, this clone should also be kept up to date and cloning should be done on a regular basis. Is there any reason not to do unattended cloning? As in, when I leave on a Friday afternoon,

Blockpull behavior when interrupted
Hello, I use snapshot-create-as followed by blockpull when creating external snapshots of VMs. This works well, however I am curious about the behavior of blockpull after an unexpected shutdown (or SIGKILL). If a blockpull is in progress and an unexpected power loss occurs, will the VM continue to reference the backing file for the parts of it that have not yet been copied? Or, will will the disk

Blockpull while domain is shutoff
Hi Libvirt, Is there a command that performs the same operation as blockpull while a domain is shutoff? I have a backing chain base <-- A <-- B that I would like to shorten to base <-- B It seems like blockpull B, setting --base <path-to-base> does this, but only when the domain is running. Thanks!

Live Snapshot and Rebasing using blockpull

What''s eating my disk space? Missing snapshots?
Please can someone take a look at the attached file which shows the output on my machine of zfs list -r -t filesystem,snapshot -o space rpool/export/home/matt The USEDDS figure of ~2GB is what I would expect, and is the same figure reported by the Disk Usage Analyzer. Where is the remaining 13.8GB USEDSNAP figure coming from? If I total up the list of zfs-auto snapshots it adds up to about 4.8GB,

Migrating ZFS/data pool to new pool on the same system
Can anyone confirm my action plan is the proper way to do this? The reason I''m doing this is I want to create 2xraidz2 pools instead of expanding my current 2xraidz1 pool. So I''ll create a 1xraidz2 vdev, migrate my current 2xraidz1 pool over, destroy that pool and then add it as a 1xraidz2 vdev to the new pool. I''m running b130, sharing both with CIFS and ISCSI (not
