similar to: vm in qcow2 runs on host A but not on host B

Hi List, i installed qemu-agent on a windows server and it is working as expected. I can send via virsh commands. I already performed successful an online backup of an windows server. Now my question is, is it possible to execute commands on the windows server via qemu-agent? I want to shutdown the MSSQL Service before doing backups. Is that possible? i dont find any helpful pages in net.

This might be related to the configuration of the virtual machine. A machine configured to have cpu X might not start up when it is changed to cpu Y. We also observed that a windows host does not boot on a ubuntu host with the default kvm configuration.

Hello, i´ve done 2 vm with qcow2 disks and created them with qemu-img with prealloc=metadata. Virt-Manager shows me under the performance settings for the Storage, Cache= Hypervisor Default IO= Hypervisor Default Is this the best setting? Or do i choose "native" IO on prealloc=metadata created disks? And do i have to change Cache too? The Virtualisation Host is gento linux, the

Dominik, What's the point of including a software to an OS that does not work? 2017-07-08 18:34 GMT+02:00 Dominik Psenner <dpsenner@gmail.com>: > I just wanted to point out that you're only resolving the symptom, not the > actual cause.

Just a little catch-up. This time I was able to resolve the issue by doing: virsh blockjob domain hda --abort virsh blockcommit domain hda --active --pivot Last time I had to shut down the virtual machine and do this while being offline. Thanks Wang for your valuable input. As far as the memory goes, there's plenty of head room: $ free -h total used free

Yeah, I know. Sorry for my demanding attitude. Any hints how I could start debugging the problem? 2017-07-09 18:12 GMT+02:00 Dominik Psenner <dpsenner@gmail.com>: > You can't expect anyone to step up happily to fix a problem you > experience.

Dominik, As far as I am concerned the command provided by Andrea disables libvirt-guests service at boot. jedrek@Home:~$ service libvirt-guests status ● libvirt-guests.service - Suspend Active Libvirt Guests Loaded: loaded (/lib/systemd/system/libvirt-guests.service; *disabled*; vendor preset: enabled) Active: inactive (dead) Docs: man:libvirtd(8) http://libvirt.org When

Hi Dominik, So what is going on on my computer with the script *libvirt-guests.sh*? Why is it hanging on it? How should I address this problem? I really appreciate your help!

Hi again, just today an issue I've thought to be resolved popped up again. We backup the machine by doing: virsh snapshot-create-as --domain domain --name backup --no-metadata --atomic --disk-only --diskspec hda,snapshot=external # backup hda.qcow2 virsh blockcommit domain hda --active --pivot Every now and then this process fails with the following error message: error: failed to pivot

I'd say switching the disk from IDE to virtio should be the very first step - and while you're at it, you might as well use virtio for the network interface too. --  Andrea Bolognani / Red Hat / Virtualization

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
