Hello! For some reason, when I'm trying to convert a RAW disk, which is stored on zfs-local, to QCOW2, the format dropdown list is inactive. But if I try to move (Move Disc button) the disk to remote storage (SMB share), the dropdown is active. It seems like I've missed something during the...

Hi Everybody, a few days ago my pair of USB drives running my hypervisor (lesson learnt SATA SSDs on their way) crashed and have been corrupted. I have been able to access the NVME drive that the VMs ran on. This drive is intact I think, I have been able to access the qcow2 files from it and...

Hi, I want to migrate form HyperV to Proxmox but keep my VMs. After some reading I found out that you can export the VMs from HyperV, convert them to qcow2 with Starwind V2V and continue to use the virtual hard disk in proxmox. After doing so I copied the filename.qcow2 file in the root...

I have some VMs on AWS that are running some very old applications that I'd like to move to Proxmox. I don't have a good way to reinstall/recreate the apps running on those VMs. We're talking code that's like 15 years old and the developers are long gone and I have no one that supports these...

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"?

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...

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...
