Hello, I am working on my PhD thesis and it would be really helpfull if someone could advise me, whether can Virsh create snapshots of VMs using copy-on-write. Thanks for reply. Juraj

Hello, I am working on a script to automatically create live snapshots of running VMs using qemu-kvm 1.4.0 and libvirt 1.0.2. If a VM has multiple disks, I'd like to back them up individually with separate calls to snapshot-create-as, so I can more easily manage the disk images. The code I have now is essentially as follows: virsh snapshot-create-as --domain "vmname" --name

what the difference between ` virsh save ` and `virsh snapshot`? are they all used for backup for vm?have any details articles to introduce vm bakcup or image bakcup with libvirt? thanks in advance. liuzhijun -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I was trying to take live snapshot of VMs, but I got the following error: [root@localhost ~]# virsh snapshot-create-as 1 test desc --live --memspec file=mem.bak,snapshot=external --diskspec vda,snapshot=external,file=/root/root.bak.qcow2 error: Operation not supported: live disk snapshot not supported with this QEMU binary I upgraded my qemu-kvm 0.12.1 to qemu 1.2, the error still

Hi Kashyap, Thanks for your answer! Unfortunately my use case requires cloning the exact memory state, so I won't be able to use virt-sysprep. But the snapshot command looks like something I could use. Could you suggest how to proceed and create/start a new vm from that snapshot?

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

Hi, My use case involves creating duplicates of saved virtual machines. Tried with virt-manager and with virsh but so far it seems like this case is not supported by these tools. Does anyone know how I could achieve the above? Thanks, Michael

Everyone, I am trying to create external snapshots of a kvm guest machine and have not been able to do so. In accordance with : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-troubleshooting-workaround_for_creating_external_snapshots_with_libvirt I have used the command line : snapshot-create-as --diskspec

Hi, I have a win10 guest on a fedora32 system and have some questions as I explore using external snapshots as a form of backup in case of a Windows failure (as in, it won't boot or is completely irrecoverable) as well as revision control (to be able to rollback changes after a failed app install, etc). The first hit on Google for external snapshots involves a RHEL7 document that talks

I scripted the creation of snapshots and it works fine. Now I'd like to run the script as non-root. virsh snapshot-create-as --domain hq-live-v01 \      --name snappy \      --diskspec vda,file=/var/lib/libvirt/images/hq-live-v01.snappy,snapshot=external \      --diskspec vdb,file=/var/lib/libvirt/images/hq-live-storage.snappy,snapshot=external \      --disk-only --quiesce --atomic This

Hi, I'm trying to create a snapshot on a specific disk by using diskspec option. However, libvirt/virsh seems to ignore it and takes a snapshot of all disks. Am I using this option incorrectly? In below examples, I'm trying to snapshot only vdb. However even vda is getting snapshotted regardless of diskspec. Is this a known issue? I'm on CentOS 7.1, libvirtd (libvirt) 1.2.8, virsh

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

Samba has a shadow_copy module to serve read-only snapshots to windows clients. I tried to use snapshotting in freebsd 5 (haven''t tried 6), but couldn''t get it stable. I''m really looking forward to getting it going on Solaris.

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

hi there, i begin to install shadow copy VFS mod function in samba 3.0.24-6etch9, after i see the same function at win2003srv, i think it could be very useful, if i gonna make it under DEB, but at the moment i'm really get stucked, i try to describe what's the point now; 1 - load shadow_copy mod in smb.conf vfs objects = shadow_copy 2 - install shadow copy client in WinXPProf 3 -
