similar to: what does "virsh destroy" really ?

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

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 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 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 have a domain (SLES 10 SP4) running with KVM. Time is very wrong when booting unless ntp synchronizes. What can i do ?

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 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'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 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 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 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

Hi, i have several vm's running on KVM hosts. Recently i found out that the time in the log-files of the guests (/var/log/libvirt/qemu/xxx.log) is wrong. The time on the guest itself is right, just the time in the log-files is one hour back. Windows and linux vm's are affected. Also on another host the same. Changing the clock offset does not have any influence, still the wrong time in

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
