Is there a better way to share HDD between multiply KVM guests at the same time then NFS? I have MDADM RAID 1 with all of my info and also I'm planning to take my Nextcloud to a KVM guest and want Nextcloud to be able to read/write all of my files on host RAID 1 and also at the same time other KVM guests need to be able to read/write the same RAID 1.
Thanks in advance
