How to setup Unraid share 9p Mode within a Libreelec VM

[wacko37]

Anybody have an experience in implementing the Unraid Share 9p Mode within Libreelec? 

 

There is no 9p mount script within Libreelec, like the scripts for SMB & NFS.

 

The problem arises when trying to mount the share within Libreelec, all the info I can find on the unraid forums talk about utilising "fstab" to mount the share but libreelec has no "fstab" function.

 

See here:https://forum.libreelec.tv/thread/22051-can-t-edit-fstab/

 

I can setup NFS but seems pointless using the network when they are on the same system.

If it doesn't support fstab the only option you have is to manually mount the share somewhere:

mount -t 9p -o trans=virtio,version=9p2000.L,posixacl,cache=loose MountTag /path/to/mount/point

 

Maybe you can create a startup script in libreelec

Hi there ghost82, its only been 24hrs....lol

 

I've ran your code in libreelec ssh to test 1st, but i keep getting an error

Does the folder /storage/test exists in libreelec?

in libreelec:
 

mkdir /storage/test

Yes sure does, created it via WinSCP

Can you double check this in the libreelec terminal: cd /storage/test

Would the capital M in Multimedia cause and issue?

 

[ghost82]

now the message changed, it's no more no such file or directory but no such device, and it makes me think about the Multimedia tag, but I don't know what's wrong..

ok I changed the unraid share mode to manual and edited the mount tag to multimedia  (all lower case) but still same error

I'm not sure libreelec is capable of mounting 9p..qemu wiki says to enable some things in the kernel configuration of the guest:

https://wiki.qemu.org/Documentation/9psetup

and since libreelec does not support running in virtualization environments I don't think it's capable..You may ask in libreelec forum if libreelec is able to mount 9p shares, but I think its default kernel is not configured to be able to do it.

 

Why not using any other linux distro and install kodi on it instead of libreelec?it seems it's such limited..It's very good for multimedia streaming, I run it in a raspberry, but in a vm, it would not be my primary choice at all.

Or why not using a smb share: it's true that 9p should be able to give more performance, but there should be not such a difference..

I totally agree with you here, everything has been a struggle to implement on libreelec via Unraid VM. This is my 1st ever VM on any system and its been nothing but painful to say the least...... hence my rant on 1 of the other unraid threads.

 

I wish I have of had the foresight and knowledge I have gained over the last few days back then before I started down this route

 

Libreelec advertise "just enough os for kodi" which sounds perfect for a VM in my mind, but as you say it has to many limitations.

 

Im currently using nfs and FYI I reluctantly rearranged my audio hardware to accommodate the lack of HDMI audio.

 

What distro would you recommend with your expertise?

Yes I read but please take into account that unraid should be the latest to blame because virtualization is not developed by unraid, but it's based on qemu/libvirt: unraid gives you a gui, very useful for people approaching virtualization to be able to interact with qemu and libvirt. Passthrough is nothing but vfio, which is a feauture of linux kernel.

You can have the same virtualization capabilities with any other os by installing on it qemu and libvirt, with a lot more developement since you need to configure most of the time all the things manually, and it could be very tricky, especially if you want to passthrough things, and especially igpus. Everything can happen, bios bugs, host os bugs, libvirt/qemu bugs, guest os bugs, ovmf bugs..it's not like just put a check here and another check there and run a vm with gpu, audio, usb, etc..unraid tries to do this, but obviously with some limitations.

Approaching virtualization requires a lot of time, I started about 3-4 years ago and I keep learning new things even now, without taking into consideration that qemu and libvirt are updated and you need to keep up to date with the changes.

 

However, in your case, most of the things on the host side seem to work, igpu video is passed through, igpu audio too, which in my opinion are the most difficult things to make them work.

I would not know what distro to recommend, I would go for most popular  linux distros, arch or manjaro for example, even a windows vm can work with kodi (but I would go with linux since you are mostly sure that igpu works, unless you want to experiment windows).

As you can see from the source:

https://github.com/LibreELEC/LibreELEC.tv/blob/master/distributions/LibreELEC/kernel_options

 

there's no trace of 9p...

Cheers @ghost82 you've been a legend over the last few days to say the least! 

 

If I've learnt anything over the last few days is just how complex VM's actually are, just so many variables it's impossible to keep track of. 

 

I think I'll stick with Libreelec for now, to much time spend and it does work.

 

Windows.....F$%k no! I have installed it twice as a vm recently and both times it corrupted itself during windows updates. It's bad enough natively....lol

 

thanks for all your help
