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

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

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!

[help] Does "virsh blockpull" works on live virtual machine
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,

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,

Live Snapshot and Rebasing using 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

Pivot without copy
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

libvirt-python blockPull
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!

Re: Pivot without copy
Hi Eric, Thanks for the info. I see the value in this, but it isn't quite what I was looking for. Basically what I want to do is to switch between snapshots quickly. For instance, I am currently working on designing a HA SQL implementation with failover. So right now I have 5 VM's running postgresql as a replication group. I am trying a lot of different things and often have to take a

Re: Attached disk blockpull
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.

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
