I don't think it is VDO, but I can be wrong.
My ovirt setup is VDO + Gluster v7.7 + CentOS 7.8 . I tested libgfapi a long
time ago and it worked.
If you wish you can ask in the ovirt users' mailing list how qemu is using
libgfapi.

Just try with the virt group enabled on a test setup .

As I wrote
btw, all I wrote before was about raw file format,
if it is qcow2 then, using gfapi:
virsh create /kvmconf/stewjon.xml

Have you set the 'virt' group of settings ? They seem to be optimal , but keep in
mind that if you enable them -> you will enable sharding which cannot be
'disabled'

The fact that it works on C7 is
Libgfapi brings far better performance , but qemu has some limitations.
If it works on FUSE , but not on libgfapi -> it seems obvious.
Have you tried to connect from C7 to the Gluster TSP via libgfapi.
Also, is SELINUX in enforcing or not ?

Yes, and several vms do not rely on the same mount point...
but qemu has some limitations.

Not obvious for me, we tested vdo locally, i.e.

We are testing gluster 8 on centos 8.2 and we try to use volume

This is 2 nodes setup.
There is lvm created over vdo, and xfs filesystem.

Test vm runs just fine if we run vm over fuse:
/root/pool/ is fuse mount.
but if we try to run:
