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 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 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

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

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'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 several domains running on a 2-node HA-cluster. Each night i create snapshots of the domains, after copying the consistent raw file to a CIFS server i blockcommit the changes into the raw files. That's running quite well. But recent the blockcommit didn't work for one domain: I create a logfile from the whole procedure:

Hi, i have a two-node cluster with several domains as resources. During testing i tried several times to migrate some domains concurrently. Usually it suceeded, but rarely it failed. I found one clue in the log: Dec 03 16:03:02 ha-idg-1 libvirtd[3252]: 2018-12-03 15:03:02.758+0000: 3252: error : virKeepAliveTimerInternal:143 : internal error: connection closed due to keepalive timeout The

Hi, currently i'm following https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit. I 'm playing around with it and it seems to be quite nice. What i want is a daily consistent backup of my image file of the guest. I have the idea of the following procedure: - Shutdown the guest (i can live with a downtime of a few minutes, it will happen in the night). And i think

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

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. This is the error: VirtualDomain(vm_snipanalysis)[14322]: 2019/09/18_16:56:54 ERROR: snipanalysis: live migration to ha-idg-2 failed: 1 Sep 18 16:56:54 [6970] ha-idg-1 lrmd: notice: operation_finished:

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, 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 have a SLES 11 SP2 64bit host with three guests: - Windows XP 32 - Ubuntu 12.04 LTS 64bit - SLES 11 SP2 64bit The SLES guest shuts down with the host shutdown. The others not. When i shutdown these two guests with the virt-manager, they shutdown fine. ACPI is activated in virt-manager for both of them. Acpid is running in the Ubuntu Client. When the host shuts down, the two guests get a

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
