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 following operations）: (1) the host machine control VM test virsh snapshot-create-as mix snap1 --diskspec vda,file=/tmp/mul/loop-mix-commit-rebase/snap1-mix.img -...

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 virsh support blockcommit when VM...

Hi, Did something dumb - had two VM hosts with DRBD mirroring of VMs on the same UPS, which failed and crashed them both. While I've got VMs running now on both, "virsh list" and "virsh start" and so on are just hanging. I'm not seeing it log anything in these instances - just hanging. Both systems are Ubuntu 10.10, one with the stock libvirtd 0.8.3 and one with 0.9.12 compiled from source. They each brought up their autostart VMs okay. But I...

.... Does anyone have suggestions on how to proceed? Is there a way to get what I want? The environment: CentOS 7.0 with latest patches. The goal: I want logwatch to include a report on the status of kvm virtual computers. The problem: When run from anacron, SELinux denies permission for the virsh utility. Here is a portion of the logwatch output: --------------------- KVM libvirt status report Begin ------------------------ Date Range: yesterday /etc/logwatch/scripts/services/libvirt: line 15: /usr/bin/virsh: Permission denied ---------------------- KVM libvirt status report End --...

Hi, Recently We've upgraded some KVM hosts from Fedora 29 to Fedora 30 and now experience broken VM configurations on filesystem after virsh blockcommit. Commands "virsh dumpxml ..." and "virsh dumpxml --inactive ..." is showing diffrent configuration than the one on filesystem. In case of restart libvirtd or system reboot, there are broken VM xml configurations on filesystem. Everything is OK on Fedora 29 KVM host...

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...

Hello, Does anyone know where full documentation for virsh can be found? Or if the there are any plans to update the man page? The man page lists far fewer commands than virsh lists from its interactive mode when you type help. I noticed this when I was trying to figure out the difference between pool-destroy, and pool-delete. The help entries in the...

Hi, Has anyone met the same problem that virsh hangs when there are some backup jobs running on the kvm host? I use dirty bitmap supported by qemu to do backups every 6 minitues. About a few hours later, I ran 'virsh list', It hung. Then I stopped the backup jobs ?nothing was getting better. I had checked the libvirt logs ?but found no...

Hi, I’m new here so apologies if this has been answered before. I have a box that uses ZFS for everything (ubuntu 17.04) and I want to create a libvirt pool on that. My ZFS pool is named „big" So i do: > zfs create big/zpool > virsh pool-define-as --name zpool --source-name big/zpool --type zfs > virsh pool-start zpool > virsh pool-autostart zpool > virsh pool-list > virsh vol-create-as --pool zpool --name test1 --capacity 1G > virsh vol-list zpool Everything seems to work (no error message, vol-list shows the...

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 1.2.8 [r...

Pass -q to virsh if virt-v2v was run with -q, to reduce its output in quiet mode. Unfortunately this does not currently work in virsh as it should, see RHBZ#1358179, so only after that bug is fixed this change can actually take effect. --- v2v/output_libvirt.ml | 20 ++++++++++++-------- 1 file changed, 12 insert...
