Alpine ZFS as root for Xen Dom0

Hello,

I'm new to Alpine and am a bit inexperienced,

I want to try and use Alpine as a hypervisor with ZFS as the Dom0 file system.

I've downloaded the Xen image and installed it, and downloaded ZFS using apk, but I'm having trouble setting up ZFS and can't find any guides anywhere.

Here's where I'm stuck:

# modprobe zfs
   modprobe: FATAL: Module zfs not found in directory /lib/modules/4.4.52-0-grsec

ZFSonLinux site bug site says check dkms status, but dkms does not seem to be part of Alpine

What should I do from this point?

Thanks
Avery
