similar to: automatically reverting to a snapshot

Dear all, I created some snapshots, a long time ago, using the xml description option, so the snapshots have a name with a space in it... Really a bad choice apparently, since it seems impossible to delete them now: I cannot find how to enter the snapshot name properly due to the space. Quotes don't seem to help; escaping the space doesn't help either. Anybody knows how to solve this?

Hi everyone, Is there an easy way to find out which files has changed between two snapshots? Currently I''m doing a # rsync -arvn <snapshot1> <snapshot2> and it creates a list. But rsync needs to go through the whole filesystem and compare files. It would be nice if zfs would have this option builtin. Regards, Nickus

Is there any way to get the latest Qemu to run on CentOS 7? I'm looking for a way to create backup snapshots, but the current install says: [root at vhost1 ~]# virsh snapshot-create-as myvm snapshot1 "snapshot1 description" error: Operation not supported: live disk snapshot not supported with this QEMU binary -- Robert

Hello, I am experimenting with libvirt for my diploma. I set up an environment, where I can stop, resend, generate messages for libvirt. I am capable also standing between client and server and analyze the number of current procedure and decide what to do next ( I mean rpc procedure). So, for example I want to always drop creating snapshots and send an error to client with my custom message (NOT

Hi, all, Environment: S10U3 running as VMWare Workstation 6 guest; Fedora 7 is the VMWare host, 1 GB RAM I''m creating a solution in which I need to be able to save off state on one host, then restore it on another. I''m using ZFS snapshots with ZFS receive and it''s all working fine, except for some strange behavior when I perform multiple rollbacks and receives.

Hi folks, first post :) I'm running Redhat 6 x64 with ibvirt-0.10.2-18 and qemu-img-rhev-0.12.1.2-2.355 My question is, if I do something like the following..

Hi, i just realized that i have a guest with two disks. What would be the appropiate way to snapshot both of them ? virsh snapshot-create-as --domain guest --diskspec vda,file=/path/to/snapshot/snapshot1.qcow2 -disk-only --atomic && virsh snapshot-create-as --domain guest --diskspec vdb,file=/path/to/snapshot/snapshot2.qcow2 -disk-only --atomic or virsh snapshot-create-as --domain

I am unable to convert a vm using virt-v2v. From the trace and debug logs I am unable to understand the cause of the problem. I assume it is a permission or configuration issue but I don't know where to start looking. The following command was issued: LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 virt-v2v -ic qemu+ssh://xxx at 192.168.xxx.xxx/system -o rhev -os 192.168.xxx.xxx:/mnt/exports -of

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

I''ve been saving up a few wishlist items for zfs. Time to share. 1. A verbose (-v) option to the zfs commandline. In particular zfs sometimes takes a while to return from zfs snapshot -r tank/volumes at foo in the case where there are a great many iscsi shared volumes underneath. A little progress feedback would go a long way. In general I feel the zfs tools lack sufficient feedback

So I decided to do a quick test using the Linux kernel source tree since it has lots of files. I duplicated a tree, used 'find . -type f -exec chmod 444 {} +' to make read only files for rsync to want to chmod, then used cp -al to make several duplicate trees using hard linked files. An rm -rf on one such tree took .97 seconds while an rsync deletion took 1.25 seconds. Clearly I

I am trying to run a 2d overhead ultima type game through wine but have some problems. At one point it would run but would refresh the slides of the pictures about once every 5-8 secs and then crash after about a minute or so.

Hi, currently i'm following https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit. I 'm playing around with it and it seems to be quite nice. What i want is a daily consistent backup of my image file of the guest. I have the idea of the following procedure: - Shutdown the guest (i can live with a downtime of a few minutes, it will happen in the night). And i think

I had intended to come back to this but because I didn't really think I had anything to add to the discussion I put it at a low enough priority that I forgot about it. But I saw your bug report and was surprised to see that I was already unhelpful on this topic but because that original poster didn't have access to do an rm while you are trying to get a performance boost. I have
