Hi, how can i shutdown a windows 7 vm although someone is logged on to that vm via RemoteDesktop ? Currently libvirt waits 5 min for the vm to shutdown and then switches it off.

Hi, i'd like to establish a HA-Cluster with two nodes. My services will run inside vm's, the vm's are stored on a FC SAN, so every host has access to the vm's. But how can i keep the config files (xml-files under /etc/libvirt/qemu) synchronised ? Is there a possibility to store the config files somewhere else ? E.g. a partitition with ocfs2 on the SAN ? If not, what would you do

Hi, i have a weird problem. I have a vm (KVM) which seems to run fine. I believe the respective config file for this vm is /etc/libvirt/qemu/MausDB.xml. This is it: ========================================================= <domain type='kvm'> <name>MausDB</name> <uuid>d4c7956c-b57f-967a-0454-99835a3a740b</uuid> <memory

Hi, i'd like to create snapshots of my running vm's. I have several hosts with SLES11 SP4 64bit. I use libvirt 1.2.5-7.1 . VM's are Windows 7, SLES, Ubuntu, Opensuse. I use raw files for the vm's. I try to orientate myself by http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit . The hosts are backuped every night by a network based backup solution (Legato). My

Hello, I am working on my PhD thesis and it would be really helpfull if someone could advise me, whether can Virsh create snapshots of VMs using copy-on-write. Thanks for reply. Juraj

Hi, i asked already a time ago about snapshots. I have some guests, each resides in a raw file, placed on an ext3 fs which is on top of a logical volume, for each guest a dedicated lv. The raw is not a "must have", if there are obvious reasons i can convert them to a qcow2. What i want is a consistent backup of each guest taken overnight. If possible i won't have downtime. I can use

Pacemaker always knows where its resources are running. Query it, stop the domain, then use the queried location as the host to which to issue the snapshot?

Bernd, another option would be a mismatch between the message that "virsh destroy" issues and the message that force_stop() in the pacemaker agent expects to receive. Pacemaker is trying to determine the success or failure of the destroy based on the concatenation of the text of the exit code and the text output by virsh; if either of those have changed between virsh versions, and

Hi, i wanted to benchmark a windows guest, compare standard driver and virtio driver. I installed the domain first with an IDE disk. I followed https://pve.proxmox.com/wiki/Paravirtualized_Block_Drivers_for_Windows to install the virtIO driver. In the device manager my VirtIO disk is recognized as a VirtIO SCSI disk from RedHat which seems ok for me. But the driver is, following the device

Hi, what does "virsh destroy" with the domain ? Send a kill -9 to the process ?

Hi, i have a two node cluster with virtual guests as resources. I'd like to snapshot the guests once in the night and thought i had a procedure. But i realize that things in a cluster are a bit more complicated than expected :-)) I will shutdown the guests to have a clean snapshot. I can shutdown the guests via pacemaker. But then arises the first problem: When i issue a "virsh

Hi, i have a strange situation: A domain is still running where domblklist points to a snapshot file and also dumpxml says the current drive is that snapshot file. But the file has been deleted hours ago. And the domain is still running. I can login via ssh, the database and the webserver are still running, domain is performant. How can that be ? Also lsof shows that the file is deleted:

Hi, i try to run virt-manager on a SLES 11 SP1 box. I'm using kernel 2.6.32.12 and virt-manager 0.9.4-106.1.x86_64 . The system is a 64bit box.

Hi, i'm playing a bit around with vcpus. My guest is Windows 10 1903. This is the excerpt from the config: ... <vcpu placement='static' current='2'>4</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no'/> <vcpu id='1' enabled='yes' hotpluggable='yes'/> <vcpu id='2'

Hi, Is it possible that "virsh destroy" does not stop a domain ? I'm asking because i have some domains running in a two-node HA-Cluster (pacemaker). And sometimes one node get fenced (killed) because it couldn't stop a domain. That's very ugly. This is also the reason why i asked before what "virsh destroy" really does ? IIRC a kill -9 can't terminate a

Hi, i have some virtual machines running on logical volumes formatted with OCFS2. I'd like to snapshot the running guests to backup them easily afterwards. The files of the guests are big (100 - 300GB), but the content changes only slowly. So i thought that rsync would be a great benefit because it justs transfers the difference between the current file and the one backuped one day before. I

Hi, i'd like to rsync some image files from virtual hosts each night. The image files are between 50GB and 400GB big. I thought rsync would be the appropriate solution because it just transfers the differences, not the whole file. But nevertheless rsync takes hours. The images aren't much modified over the day, i would expect just some tens of megabyte needed to be transfered. I have the

Hi, i have a two node HA-Cluster with several domains as resources. Currently it's running in test mode. Some domains (all on the same host) stopped running, virsh list shows them as "paused". All stopped at the same time (11th of may, 7:00 am), my monitoring system began to yell. I don't have any clue why this happened. virsh domblkerror says for all the domains (5) "no
