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

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

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

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,

Hi , Working on the simple POC : Advanced snapshot using libvirt and qemu . Following are the exact steps which are followed . 1.

Unfortunately, for some reason, I can not shutdown the vm, and exectue the "virsh blockpull" command. Can I execute the "virsh blockpull"

Hello, We''re a team of 4 final year computer science students and are working on generating a diff between file system snapshots using the send receive code. The output of our utility looks like this- (I''ve tested it on a small subvol with minimal changes just to give an idea) root@nafisa-M-6319:/mnt/btrfs# btrfs sub diff -p /mnt/btrfs/snap1 /mnt/btrfs/snap2

Hi, WARNING: Long post ahead I have an issue when starting multipathd. The kernel complains about "blk_cloned_rq_check_limits: over max segments limit". The server in question is configured for KVM hosting. It boots via iBFT to an iSCSI volume. Target is COMSTAR and underlying that is a ZFS volume (100GB). The server also has two infiniband cards providing four (4) more paths over SRP

Hello ZFSland, Is there any significance in the fact that the bandwidth/read figures for a simple cpio into a ZFS filesystem should be multiples of 21.3K (when non-zero) as follows? What could determine this figure? Do I need to read a manpage? ;-) Thanks... Sean. ----- [root at global:/36g2] # zpool iostat 3 capacity operations bandwidth pool used avail read

Hello. The Changelog of qemu-2.0.0 mentioned "Live snapshot merging". Someone has an idea what could be ment by this? I'm asking because i'm still struggling with finding a reliable backup solution for running kvm machines. Blockcopy is my current solution. best regards Thomas

Hi, I have a server, snap1 10.8.5.10, that runs samba, and have users created by using useradd (but not added them to snap1's smbpasswd). I'd like for users on our primary samba server, archives1 10.8.5.2, to be able to type in \\snap1\username in windows and have the snap1 server take them to their home directory on the snap1 server, but athenticate the users against

I have just upgraded my jumpstart server to S10 u2 b9a. It is an Ultra 10 with two 120GB EIDE drives. The second drive (disk1) is new, and has u2b9a installed on a slice, with most of the space in slice 7 for the ZFS pool I created pool1 on disk1, and created the filesystem pool1/ro (for legacy reasons). I them moved my data from the original disk0 UFS file system to pool1/ro. Initially I

Howdy All, I''ve a bit of a strange problem here. I have a filesystem with one snapshot that simply refuses to be destroyed. The snapshots just prior to it and just after it were destroyed without problem. While running the zfs destroy command on this particular snapshot, the server becomes more-or-less hung. It''s pingable but will not open a new shell (local or via ssh) however
