ZFS pool shared to Linux Guest using VirtualBox Shared Folder.
Tested with VirtualBox 6.1.0, 6.1.6, 6.1.12 (all with extension packs).
/mnt/ztank is the Shared Folder via VirtualBox setting
/workingpool is a zpool from 5 12TB drives that are passthrough to the guest.
I run rsync from /mnt/ztank to /workingpool and after 100GB to 500GB of traffic, I get a kernel stack dump. Every time.
