...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 for it seems have tab completion built right into virsh shell. 4. Created a disk-only snapshot of a vm CO1 called capture1 but the syntax of blockpulling seems to be opposite from what has been advertised on Fedora and other relative wikis. Check below and the error with first blockpull command.

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

Hi all, I have a kvm virtual machine running (qemu version 2.0), and I had took several external snapshots of the disk( using "virsh snapshot-create-as"). Now, the existed disk files relationship look like: base <- snap1 <-snap2 <- current using disk file. Now I want to remove snap1 and snap2, and let current disk using the base image file as back file directly. Unfortunately,

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

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!

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,

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

Hello, I am looking for a solution for live backups of running KVM hosts. I recently read this article which highlights the following method: http://www.linux-kvm.com/content/first-look-virtual-machine-online-disk-snapshots-coming-fedora-18 1. virsh snapshot-create-as to create the snapshot 2. cp myvm.qcow2 myvm-backup.qcow2 to copy off the now read-only backing image file 3. virsh

Hi Libvirt, Does libvirt-python currently support adding a base path to virDomain.blockPull()? In particular, I would like to have the behavior of the following virsh command (from https://kashyapc.wordpress.com/2013/01/22/live-backup-with-external-disk-snapshots-and-libvirts-blockpull/) in libvirt-python: [image: image.png] Thanks!

This is a libvirt question, so asking it on the qemu-block might not get you an answer that quick, ... or ever if I didn't notice your other question also addressed incorrectly.

Hi, Is it possible to "pivot" to a new image without doing blockcopy or blockpull? I know how to use snapshots and blockpull to create a new image and pivot to using it live, but what I would like to do is to have a VM switch from using imageA.qcow2 to image2.qcow2 while running. I don't see why this wouldn't be possible since some of the existing libvirt tools can do this when

Correct - qemu doesn't provide full functionality for merging in all directions. And even though upstream qemu has been adding more pieces (for example, they recently added
