Hi all,
I'm trying to setup virt-manager with ZFS als storage on my Arch box. I
have created a pool named virt-pool and tried to use it as storage. First
with virt-manager and then in the terminal with virsh but I'm always
getting the following errors:
*virsh # pool-define-as --name zfsvirtpool --source-name virt-pool --type
zfserror: Failed to define pool zfsvirtpoolerror: internal error: missing
backend for pool type 11 (zfs)*
But ZFS seems to be working fine:
# zpool status
pool: virt-pool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
virt-pool ONLINE 0 0 0
x ONLINE 0 0 0
errors: No known data errors
libvirt and VMM also. These are the installed versions:
Virtual Machine Manager v.1.4.3
virsh v.3.7.0
libvirtd (libvirt) 3.7.0
I have found that there was a bug last year which is supposed to be fixed:
*https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827245
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827245>*
So why I'm getting this error. Is something wrong with my setup?
Regards,
Nick

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.

@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?

I have set root in both for user and group in the qemu.conf and changed the
file permissions to root like it was before. Now I'm getting this error:

This looks like the error message was cut off. Isn't there a full error
message somewhere in the logs, e.g. journalctl?
Anyway, qemu is dying because .. and this is where the message would
help. To help us identify the reason. Maybe
/dev/zvol/virt-pool/vmm/fedora doesn't exist (just a rough guess)?

2) storage backends are static. While we have libvirt drivers in

This was changed some time ago. Backends are loadable now:
src/.libs/libvirt_storage_backend_disk.so

Similarly to driver backends they are loaded at start of libvirtd.

By default is qemu:///system activated but I had to change to
qemu:///session because I was getting errors. I created a VM with
qemu:///session and it was running without any issues. But it didn't work
for ZFS Volums. I suppose the other change that it was necessary is set the
user to root in the /etc/libvirt/qemu.conf. I have created a new volume in
VMM and installed Fedora. Everything seems to be working fine inclusive ZFS
snapshots.

it was necessary is set the user to root in the /etc/libvirt/qemu.conf.
It works if group is set to kvm...
