qcow2

Hi there, I have just finished setting up my second homelab host and come to the horrible realisation that my 2 x 2TB and 4TB disks are all LVM and have running VM's on. I tried to take a snapshot, only to realise that I cannot make a snapshot due to it being LVM on the disks. I would like to...

Using libvirt, I am creating VM on Proxmox with Scaleway. I have an ansible file that create a VM name CentOS_Base, the most important commands are: # Downloading a CentOS-7-x86_64-GenericCloud-1809.qcow2 curl https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1809.qcow2 #...

We have a Proxmox 6.1-5 Server running with a VM which has 3 harddisks configured. The virtual disks are all qcow2 files hosted on the local filesystem. The VM performance is ok even under heavy load. My problem is, that it takes ages to create a snapshot of this VM even if theVM is powered...

Hi, i would like to use QCOW2 image to my VMs, i am using BTRFS file system in PVE 7, but i found this https://forum.proxmox.com/threads/no-qcow2-on-zfs.37518/ post and there is a good question. Can I use it without loss of performance?

Moin, aktuell habe ich das Vergnügen vmWare Maschinen auf PVE zu migrieren. Alles in Allem funktioniert das auch, die Hardware wird "umgebaut" und die Treiber greifen auch. Mir stellt sich nur eine Frage: Meine lieben externen Kollegen (ein Systemhaus in NL) hat überhaupt keine Lust, mir die...

Hi I've just read this interesting blog article on jrs-s.net (he have a lot of great articles on ZFS by the way) on the topic of qcow2 vs zvol I/O performance. The interesting part was that fine-tuning the qcow2 cluster_size to match the record size ot the underlying zfs dataset could...

Hi! Please tell me how works VM snapshots in PVE? 1. I create snapshot (disk type qcow2), do some changes on disk, and snapshot size - 0 (screenshot). 2. How creates RAW-image snapshot (backend ext4) during backup VM with type "snapshot"?

I have a Ubuntu Desktop VM with two hard disks. Both reside on an NFS server and the connection is 10GbE. One disk is in raw format and one in qcow2 format. The image files are called vm-106-disk-0.raw and vm-106-disk-0.qcow2. Both are 200 GB in size and attached using VirtIO SCSI controller and...

WE have been using proxmox since day 1 and zfs since version pve version 5. I happen to notice qcow2 snapshot and zfs vm disk are too slow very relatively slow it took a lot of time a very very slow perform on zfs proxmox version 6 and up. is there an issue with zfs? Current setup System: zfs...

Hi, After being VERY upset two days ago because of Proxmox and PBS shortcomings and sneaky traps, I have decided to rebuild my whole installation from scratch. I am lucky enough to have installed PBS and have extensive backup saved in an external drive. My PBS was virtualized as a qemu virtual...

Hi, i want to shrink a vm. it is a linux vm. In the vm the system tells me a used space of 2.3gb data. The disk in Proxmox is 8tb. The file system shows me a size of 12tb. I use fstrim -av inside the vm. it shows me it shrinked 5.5gb. But the file on filesystem is still 12TB. After a reboot of...

Hi Im hoping someone can help. I am looking for a way that I can export a VM from my Proxmox server to my PC so I can create a forensic image using FTK Imager. This is for a university project involving Digital Forensics. Any help would be appreciated. Thank You

Hello everyone! I'm trying to migrate a VM from XeServer(6.5) to Proxmox(6.3-4) Until few days ago, I can do it following next steps: 1. Export VMs from XenServer like OVF ( .ovf + .vhd file) 2. Convert VM disk (.vhd file) to qcow2 format (with StarWind 2V2 Converter) 3. Create a VM with...

Hello, I am a new to proxmox. I am migrating my work load from OpenStack to proxmox. And with that regard, I need to move disks which are in qcow2 format. I am using proxmox 6.3-2 version Any ideas how can I do this? Thanks. Regards, Amey.

Hello! I've followed the tutorial on the forum to install proxmox. Everything works just fine, except one thing. I'd like to make snapshots, but if i choose the LVM what i've created (Point 7 in the installation steps), i can't change the image format, there is only RAW image format, and i...

My current installation of Proxmox 6.3-2 is configured for my vms to run on a local SSD. I have the SSD setup as an LVM. I wanted to test the snapshot feature, but I receive an error, "The current guest configuration does not support taking new snapshots" I found I can use the "Move Disk"...

When I made a system image and purchased the automatic activation product from whmcs, the automatically created parameters were correct, but the VM could not be started, and the disk was also qcow2 Use of uninitialized value in split at /usr/share/perl5/PVE/QemuServer/Cloudinit.pm line 99...

I am a total noob and currently we have a Scale Environment. Long story short I would like to use ProxMox instead of spending thousands of dollars. When I export the VM image from scale the extension is QCOW2. My question here is how do import this image into ProxMox and be up and running. What...

Hi, I am new to Proxmox and need to create a VM from a very lightweight debian distro to run a Wireguard server only and found Ubuntu 20.04 Minimal to be sufficiently lightweight while being familiar for me since I have been using Ubuntu for a while. However, when I uploaded the Ubuntu 20.04...

Hallo :) Ich habe bei mir ein kleinen Cluster aus drei Nodes und einen Server 2016 als Storage Server. Dieser Server besitzt mehrere NFS Freigaben für den Cluster wo eine Freigabe für VMs dient. Dieser ist eine einzelne SSD die nur dafür genutzt wird. Wenn ich jetzt versuche eine VM darauf zu...
