similar to: Detach disk from VM - virsh (working) vs. PHP (not working)

Thank you for your help! 1, i used vda as install disk and vdb as target disk, because i boot from the first. After setup boot order flag i was able change install disk to vdb and target disk to vda. With this configuration when i boot from vdb i can install OS with grub and after it redefine XML without vdb without problem. Thanks a lot. 2, maybe i have something wrong, but still not working:

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

Dear all, Please let me start by indicating that I am not from a technical background, so please be gentle and patient with me. I am trying to get a snapshot from my virtual machines (vm) and the following command works for all of them bar one: # virsh snapshot-create-as --quiesce --no-metadata --domain myvm myvm-state --diskspec vda,file=overlay.qcow2 --disk-only --atomic The only exception is

I hate intermittent problems ... Most of the time, my domUs launch just fine. But, occasionally I get a failure to connect a vdb or vif and the domU fails to completely launch ("xm list" shows it is present but no console activity either through "xm create -c" or through "xm console"). The log shows a stack trace in DevController.py in the area of waiting for

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

Hi, I am adding a disk to my KVM virtual server, but for some reason it refuses to honor the <address> I have tried the following 3: <disk type='block' device='disk'> <driver name='phy' type='raw'/> <source dev='/dev/nbd2'/> <target dev='vdb' bus='virtio'/>

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

Hello, I want to do a snapshot which the VM has volumes. But I want to skip the volume check when I do the snapshot. (Which means I want to do a snapshot without detaching the volume) So I try to write a snapshot XML refer by http://libvirt.org/formatsnapshot.html as following: vda is my VM basic disk (qcow2) vdb is a volume (raw) ================ t1.xml =============== <domainsnapshot>

I never thought I'd say this, but I think it's easier to do this with GRUB 2. Anyway I did an installation to raid1's in CentOS 6's installer, which still uses GRUB legacy. I tested removing each of the two devices and it still boots. These are the commands in its log: : Running... ['/sbin/grub-install', '--just-copy'] : Running... ['/sbin/grub',

I''ve had a go at determining exactly what happens when you create a filesystem without enough devices to meet the requested replication strategy: # mkfs.btrfs -m raid1 -d raid1 /dev/vdb # mount /dev/vdb /mnt # btrfs fi df /mnt Data: total=8.00MB, used=0.00 System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=153.56MB, used=24.00KB Metadata:

Package: xen-hypervisor-3.0.3-1-i386 Version: 3.0.3-0-2 Severity: important When I try to start a domU with more than 6 vdb it crash. The first time the vm does not launch and aparently wait for the loop device creation (some scripts/block add, udev --daemon and sleep 1 process running). And nothing happen until I Ctrl+C the xm create. My loop module is loaded with 64 loops. After this first

Hi, dear friend. My guest has two disks, vda and vdb. both are qcow2 local file. When guest running state. I want to take the vda snapshot of guest(just vda, no include vdb). but I met libvirt do snapshot for all disks of guest. About methods for follow: 1、 ``` bash virsh snapshot-create-as 8x0lbzvS --name sys_disk3 --disk-only --diskspec "vda,snapshot=external" ``` ``` result

Good day to all. i have problems with cdrom hot adding code. currently i using virDomainAttachDevice with type=file, device=cdrom, dev=hdc, this code works for machine with one ide hdd and one ide cdrom, but this not work for machine with only one ide hdd, and i looking for solution to hot add cdrom to machine independent of existing devices or i need way to determinate which target device
