Hi Adam, Thanks for the reply. qemu-img info /VirtualMachines/KVM/machine.qcow2**** image: /VirtualMachines/KVM/machine.qcow2**** file format: qcow2**** virtual size: 250G (268435456000 bytes)**** disk size: 174G** cluster_size: 65536 How can i do this from remote host using libvirt module ? Started using and learning libvirt so dont know how to execute it . Thanks in

You can get the block devices assigned to a VM with the following.. virsh domblklist <machine> Target Source ------------------------------------------------ vda /VirtualMachines/KVM/machine.qcow2 hdc /VirtualMachines/iso/gparted-live-0.12.1-1.iso For more detailed info, you can use qemu-img on the above returned block device qemu-img info

Hi, I'm trying to configure my ups with nut which is a locally made one. It uses a rs232 port to talk to the computer and comes with a software called "Powermanager Lite" which is provided by Richcomm and supports Windows, Linux and UNIX. According to the manual it uses the Richcomm circuitry to talk to the computer and uses a drycontact protocol. Unfortunately I couldn't

Hi,guys I wanna to get the disk snapshot size, but found nothing libvirt commands related,except qemu-img. I create two disk snapshots, but nothing return its' size [root@cskvm01 qcow2]# qemu-img info /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 image: /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 file format: qcow2 virtual

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..

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

Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of

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

Hi,? I want to label a polygon (circle or polygon) inside. As for example code? library(spatstat) x <- runif(20) y <- runif(20) X <- ppp(x, y, window=disc(0.7)) plot(X) Now I want to label that circle inside . Can some one please help me ?? Thanks.?

Hello Fairly new to libvirt. I’m hoping to both solve a problem with this question as well as learn more detail about how libvirt works. Using RHEL 6.4 and libvirt version is 0.10.2 and qemu-img version is 0.12.1.2 Using virt-manager I created a VM. Nothing unusual as far as I can see. I then added a disk. So I have a second virtio based volume which the guest then mounts as a separate

I'm unable to detach a disk from a Windows guest using the 'virsh detach-disk' command. Even though 'domblklist' shows the disk attached, and on the FIRST iteration, it says the command "completed successfully," 'domblklist will still show the disk attached and subsequent 'detach-disk' commands fail with 'no disk found whose source path or target

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

I take an internal snapshot (VM is 'shutdown' when taking it) of a qcow2 image like this: $ qemu-img snapshot -c sn1 [my_image].qcow2 I see that snapshot when asking for: $ qemu-img info [my_image].qcow but do NOT see it with: $ virsh domblklist [my_domain] is that how it is meant to be?

Dear all, I need urgent help. I am a new user of R. I got the following error anovamine<-read.table("spike cu.txt",header=TRUE) Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 1 did not have 9 elements Can anybody please help me to solve this problem why I am getting such kind of error? Thanks [[alternative HTML version deleted]]

Firstly I'd like to learn where a snapshot is stored once it has been made. I understand that the principle is that when changes occur in the VM, the difference is written to the snapshot, thus recording the differences between the date/time of the snapshot and the current value of the VM. Is that a correct assessment of the process? If that is indeed so, can I take regular snapshots and

Hi! I was reading the Wiki about 'Live Disk Backup with Active Blockcommit, https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit and see that example shown seems to be using two different names for the same file. First showing the current block device in use: $ virsh domblklist vm1 Target Source ------------------------------------------------ vda

I have an automatic process setup. It's still pretty new and obviously in need of better error handling because now I find myself in a bad state. I run snapshot-create-as across all my vms, then do zfs replication to the target backup system, then blockcommit everything. virsh snapshot-create-as --domain $vm snap --diskspec $DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic
