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, 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, 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 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.

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

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 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'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, 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 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
