) is the host FS btrfs?
The host (Fedora) FS is btrfs, the VM (Debian) uses ext4 (or maybe ext3,
I will have to check).
) are virtio modules in the initramfs (or kernel probably)?
) are you sure virtio is being used (eg. are the disks called vdX vs sdX)?
) is the disk bus set to virtio (virtmanager)?
I'm not sure. I will have to check.
) is the disk's cache mode set to none [or maybe writeback] (virtmanager)?
I don't remember, I will check.
What is the effect of this option? (What is the effect on the host FS
(btrfs)?)
) is the disk's storage format set to "raw", should be (virtmanager)?
Yes, the image type is "raw".
) is caching enabled on the image? ()
What do you mean? Is it possible to enable or disable the cache on a
specific file on the host (Fedora, btrfs)? Or you mean set cache to none
in the configuration of the VM?
probably need to change the cache mode on the disk, or if the host is
btrfs you need to flag the image with whetever is needed to prevent
continuous COWing.
Can nodatacow option of btrfs have an effect on this issue? Is it
possible to set this option for a specific file or directory?
