Debian guest, virtio "9p: no channels available"

[saures]

Hello,

my goal is to share a folder of a filesystem from the Proxmox-host with an Debian-based 'OVM' VM.
I used this this qemu manual and did the folowing:

in /etc/pve/qemu-server/102.conf

[...]
<filesystem type='mount' accessmode='passthrough'>
   <source dir='/mnt/data/media/foo/'/>
   <target dir='testfs1'/>
</filesystem>

in the omv i did
apt-get install libattr1 libattr1-dev
and added the folowing to /etc/initramfs-tools/modules:

virtio_pci
virtio_blk
#9p
#9pnet
9pnet_virtio

and did: update-initramfs -u and also a reboot.

when i now try the following:

mount -t 9p -o trans=virtio testfs1 /mnt/test/ -oversion=9p2000.L

i recieve:

mount: special device testfs1 does not exist

and
dmesg gives me

9p: no channels available

Where should i dig for the problem? I guess it depends on the guest(?). Did i even choose the right modules? Are there any apparmor rules? any hints?

thank you in advance!
kind regards.

We do not even use libvirt ....

Thank you Dietmar! Well this is kind of embarrassing. Iam a newbie to KVM & Proxmox.
Well does anyone have a link for me, how to use 9p in Proxmox or any alternative/better method, how to share a folder from the host with a guest?
I try to avoid network shares from host, for security-reasons.

I just found this thread but i dont know how to pass the startup parameters.

kind regards.

p.s. i would even be happy if there is the possibility to pass through a whole ZFS-filesystem.

p.s. i would even be happy if there is the possibility to pass through a whole ZFS-Pool.

https://pve.proxmox.com/wiki/Physical_disk_to_kvm

Add disks to kvm and create ZFS inside KVM.

Example I use.

One server share space with samba (openvz). Another server (KVM) mount it and ZFS mount pool from files (not disks). It only example I use and works.

Thank you for your help!
In the end i meant to say ZFS-filesystem instead of pool. Passing through the physical discs is not an option.
But i go with your smb way now. I accept that this seems to be the easiest way.
