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?
The BTRFS filesytem in PVE 7 only supports raw images for VMs. To answer your question, you would also be subject to the same loss of performance as is mentioned in the linked post, as BTRFS is also a cow (copy on write) file system.
