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

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,

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

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

What ''verbose information'' is reported by the "zfs send -v <snapshot>" contain? Also on Solaris 10u6 I don''t get any output at all - is this a bug? Regards, Nick -- This message posted from opensolaris.org

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,

Hi Kashyap Chamarthy: thank you very much for answer my question: 一： lead to VM filesystem becoming read-only 1： test case it lead to VM filesystem becoming read-only test case as follows: we want to snapshot for VM , to obtain VM incremental data，and use virsh blockcommit，qemu-img commit，qemu-img rebase to shorten snapshot chain. Details are as follows（when VM running state， we perform the

Hello, I have two servers where I can push VMs from one to the other by issuing the command virsh migrate --live --persistent --copy-storage-all --verbose \ test6 qemu+ssh://kvmhost2/system on kvmhost1. I can get the VM back by issuing the equivalent command on kvmhost2: virsh migrate --live --persistent --copy-storage-all --verbose \ test6 qemu+ssh://kvmhost1/system virsh

Hi everyone! I use the libvirt(version: 1.2.2) and QEMU(version: 2.2.1) to test qemu snapshot features: I tried virsh blockcommit when VM offline, the virsh blockcommit failed: the error messase as below: error: Requested operation is not valid: domain is not running when I start the VM, the virsh blockcommit work fine! my question is：we need

All, Using Centos 6.4 with provided libvirt: [root@node1 ~]# rpm -q libvirt libvirt-1.0.1-2.el6.x86_64 Assume a VM with one or more live snapshots. In virsh the VM snapshots can be listed. With virsh: - Stop and undefine this VM. - Then define (and start) this VM. The new VM does not have the list of snapshots. Is there a way with virsh to rebuild the metadata such that

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,

Firstly I'd like to learn where a snapshot is stored once it has been made. I understand that the principle is that when changes occur in the VM, the difference is written to the snapshot, thus recording the differences between the date/time of the snapshot and the current value of the VM. Is that a correct assessment of the process? If that is indeed so, can I take regular snapshots and

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,
