similar to: unable to edit existing snapshot

Sorry for the lack of information, my bad. The snapshot is an internal one and the machine is running. The whole thing was set-up by another person and left to me to cope with. The typo is mine, as the machine is isolated I cannot actually copy-paste it so have to do it in the traditional way. I am aware of the issue which come when changing HW but I couldn't do otherwise. I am only

Hi everyone! Is there any way to create snaphot for a single disk of a virtual machine. As I konw, "virsh snapshot-create-as domain_name snapshot_name --disk-only" traverses all block devices to create snapshot. However I don't want to create snapshot except for root partition. The version of qemu and libvirt I used is as follows: qemu-1.4.2 and libvrit-0.10.2

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

try snapshot-create-as like below: virsh snapshot-create-as vm --disk-only --diskspec "vda,snapshot=external" 2013/6/25 cmcc.dylan <dx10years@126.com> > > Hi, everyone, > I have found the API snapshotCreateXML() can create a snapshot for a > virtual machine, and the xml configuration file - snapshot.xml as folllows: > <domainsnapshot> >

Greetings, I am developing a platform for test and debug use. The typical scenario I want to realize is the following: I run a .qcow2 image via QEMU-KVM, the running OS is not relevant. I want to take several snapshots of both Disk and RAM status; same file, separate files doesn't matter. I just need a way to have consistent information about them (better with XML description) and the data

Hello everybody, I would like to be able to spawn several domains from a given snapshot. Here's a possible scenario: - I start from disk image A.qcow2. - I made some changes to A and I take different snapshots: 1 - 2 - 3 - While A is still running I would like to run domains B and C from snapshot 2 I don't want to revert a domain, I want to create new ones. The original should be

Hi, everyone, I have found the API snapshotCreateXML() can create a snapshot for a virtual machine, and the xml configuration file - snapshot.xml as folllows: <domainsnapshot> <name>snapshot01</name> <description>Snapshot of OS install and updates</description> <disks> <disk name='vda' snapshot='external'> <source

Thank you! But snapshot-create-as will traverse all disks of the virtual machine and create snapshots for all of them. In my case, I want to create snapshot for root disk. What's more. I understand "--diskspec" is a description of the disk. Do you mean it's used to specify a single disk to snapshot. 在 2013-06-26 09:10:31，"Gao Yongwei" <itxx00@gmail.com> 写道：

I think what you're looking for is LVM snapshots. The whole purpose of taking VM snapshots is to have a consistent image of the machine as a whole. There's lots of articles out there on LVM snapshots, here's one. http://www.tldp.org/HOWTO/LVM-HOWTO/snapshots_backup.html From: libvirt-users-bounces@redhat.com [mailto:libvirt-users-bounces@redhat.com] On Behalf Of cmcc.dylan Sent:

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

If I want to go back to a snapshot, what is the difference between snapshot-current and snapshot-revert? What happens to disk sectors of the current state when reverting to another snapshot? I'm using qemu qcow2.

Greetings, I have the following typical scenario: given one or more qcow2 base images I clone them with COW and start the VMs. At a certain point I'd like to inspect them in order to see their evolution compared to the known base images. To do so I was thinking about taking a disk snapshot of each VM and inspect its content through libguestfs (using it's Python bindings). Obviously I

Hi,all,i am using libvirt to manage my vm,in these days i am testing the libvirt snapshot ,but meet some problem: the snapshot was created from this command: snapshot-create-as win7 --disk-only --diskspec vda,snapshot=external --diskspec hda,snapshot=no but when i tried to revert from the snapshot which created from the above command ,i got error below: virsh # snapshot-revert win7

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
