Re: [libvirt-users] error: internal error: missing backend for pool type 11 (zfs)
@Michal: Thanks for your reply!
Indeed I have found a package in the AUR (libvirt-zfs) and only had to
change to the current version and add zfs-utils as dependency in the
PKGBUILD. Now I don't get the previous error anymore but I still cannot
setup a VM because I constantly get errors due to wrong permissions.
I have tried to change the permissions in:
- /etc/libvirt/qemu.conf
- /virt-pool/vmm
- /dev/zvol/virt-pool
also:
# zfs allow <user> create,destroy,mount virt-pool/vmm
didn't help.
What are the correct permissions? Which user and group?

Your libvirt was built without support for ZFS. You need to contact your
distribution manufacturer and ask them to enable it. Or build libvirt on
your own.
However, as I am writing these lines I realized two things:
1) there's no API to query loaded drivers/storage backends.
2) storage backends are static. While we have libvirt drivers in
separate modules (.so files) and load them at start up, it's not the
same story with storage driver backends. These are hardcoded into the
storage driver. Might be worth it to have them dynamically loadable too.
