Generally it is possible to format filesystem inside VM to BTRFS, however such disks cannot be managed.
Tools for managing disks (
prl_disk_tool) do not support this filesystem.
So, there is a list of limitations:
Resize of VMs using BTRFS is not supported:
# prl_disk_tool resize --hdd /var/parallels/CentOS7.pvm/CentOS7-0.hdd/ --size 150G --resize_partition Operation progress 75 %Resizing failed. Unable to resize the last volume. The file system of this volume might be damaged or not supported.
VMs with BTRFS filesystem cannot be mounted via
- Linux physical servers with BTRFS cannot be migrated into Parallels VM
It is better to avoid using BTRFS inside Virtual Machines.
