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

Hi, i have a two-node cluster running on SLES 12 with pacemaker. The cluster refused to start the domains on one node. So i took some of the domains out of the cluster and tried to start it manually. This is what happened: virsh # define /mnt/share/vm_documents-oo.xml error: Failed to define domain from /mnt/share/vm_documents-oo.xml error: cannot open /dev/null: Operation not permitted Same

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, i have a Linux domain (Ubuntu 14.04) where we like to be able to change the amount of usable memory. We have a balloon device and statistics are switched in 5 sec. rhythm. The domain shows very quickly changes (following top) when we change the memory size with setmem, but the host does not show changes in the use of memory for the respective domain. Is that expected behavior ? Host is SLES

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 guys, despite reading hours and hours in the internet i'm still struggling with "memory", "currentmemory" and "maxMemory". Maybe you can help me to sort it out. My idea is that a guest has an initial value of memory (which "memory" seems to be) when booting. We have some Windows 10 guests which calculate some stuff and i would like to increase

Hi, i'm cuurently a bit confused if a guest does have a valid snapshot or not. This is the xml: ... <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/crispor_1604/crispor_1604.sn'/> <backingStore type='file' index='1'> <format

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 knwo that virsh has its own history, but are somewhere the respective timestamps logged ?

Hi, recently i had some domains stopped without any obvious reason for me. Unfortunately i didn't find the cause. I'd like to log information about the domains that i have more information the next time this will happen. In /etc/libvirt/libvirtd.conf i have: log_level = 3 log_outputs="3:file:/var/log/libvirt/libvirtd.log" which creates enormous log files, but with logrotate and

Hi ML, i'm thinking about using balloon memory for our domains. We have about 15 domains running concurrently, and i think it might be nice if a domain requires more RAM it grabs it, and if it don't need it anymore, it releases it. But i have no experience with it. So i have some questions: - is live migration possible with balloon ? - is it stable ? - the domain needs an appropriate

Hi, i have atwo node HA-cluster with pacemaker, corosync, libvirt and KVM. Recently i configured a new VirtualDomain which runs fine, but live Migration does not succeed.

Hi, i can store the disk of a guest in a plain partition which isn't formatted. That's no problem, i did it already several times, although the promised speed increase didn't appear. But is it possible to create from such a guest a snapshot in a .sn file using virsh ? Regards, Bernd -- Bernd Lentes Systemadministration Institut für Entwicklungsgenetik Gebäude 35.34 - Raum

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?

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
