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 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 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 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

Hello. I'm struggeling a little bit with the setvcpus command. I'm trying now to get this running for a linux VM. Here is what i have: <vcpu placement='auto' current='2'>4</vcpu> Now the VM is starting with 2 CPUs. When i try to increase the number of CPUs i get: setvcpus dev --guest 4 error: invalid argument: requested vcpu count is greater than the count

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 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

Hello. Just a quick question. Is "setvcpus $windowsVM --guest 4" supposed to work? I have qemu-guest-agent (1.6.something) running inside a windows7 vm but all i get is: virsh # setvcpus windows7 --guest 4 error: invalid argument: requested vcpu count is greater than the count of enabled vcpus in the domain: 4 > 1 The xml file looks like this: <vcpu placement='static'
