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'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, 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 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 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. Here is the output: ========================= pc56846:/media/idg2/SysAdmin_AG_Wurst/software_und_treiber/virt_manager/sles_11_sp1 # virt-manager & [1] 9659 pc56846:/media/idg2/SysAdmin_AG_Wurst/software_und_treiber/virt_manager/sles_11_sp1 #

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 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

dear all, I want to perform a posthoc test for my ANCOVA: a1<-aov(seeds~treatment*length) With summary(glht(a1, linfct = mcp(treatment = "Tukey"))) R tells me: "covariate interactions found -- please choose appropriate contrast" How do I build these contrasts? Ideally, I would like to have the posthoc test for the ANCOVA including a block-effect

Hi there, I recently switched to Mac and I wonder if there is any way to get the R console to autocomplete names of list objects or slots of objects. The command line version allows to type e.g. list$ and two times the tab button and then comes up with the names of the list objects. Same for slots of e.g. Eset objects like eset. Unfortunately this does not work in the Mac R console. Is there a

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

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, This commit (I?m using the mirror to have a working link) broke C++11 compilation. Before (and still now, according to the comments in the configure script), it?s sufficient to just have ?SystemRequirements: C++11? in the DESCRIPTION file. But now ?R CMD install? fails with ?C++11 standard requested but CXX11 is not defined?, which is, according to the documentation , a lie. I can?t

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'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 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
