I have Manjaro as a host and two virtual machines. Host has SSD btrfs disk (COW disabled for VMs)
First VM has virtual disk formatted to ext4.
Second VM has virtualdisk formatted to btrfs.
I didn't install them. Both images were downloaded as ova and imported to virtualbox.
After import, I checked. There is a SSD option in settings that is not turned on. Should I check it or it doesn't matter if my host has SSD option in fstab?
I checked fstab of both VM's
First VM with ext4 has only errors=remount-ro
Second with btrfs has: subvol=@,defaults,noatime,nodiratime,nodatacow,space_cache,autodefrag 0 1
should I change anything for VM with ext4?
As for the VM with btrfs.
Should I add sdd and remove autodefrag option form fstab of this VM?
If I disabled in my Manjaro host COW for virtualbox directory then does it matter if there is nodatacow in fstab in vm?
There is 0 1 for root and 0 2 for home in btrfs vm.
For btrfs should I change it to 0 0 or it doesn't matter what's there?
Guests systems are not Manjaro. I have Manjaro as a host on btrfs SSD as I mentioned above. I use virtualbox for fun so I don't want to exhaust my real SSD to much
