[one-users] How to mount iscsi target in linux container?

[Valentin Bud]

Hello Dylan,

I am trying to get OpenNebula 3.2.1 or 3.8.3 working with Linux Containers
but I have ran into an issue. I can't find the OneLXC drivers provided by
CMRI.

Following the OpenNebula blog post [1] about OneLXC I have tried to
download them from https://github.com/cmri/opennebula-3.2.1-lxc.git but
that gives me a 404.

Big Cloud says in the second comment that the repo has been moved to
https://github.com/cmri/one.git.

I have tried to find the IM_MAD and VMM_MAD in that repo but I wasn't able
to. The blog post also mentions that there should be a
`src/vmm/LibVirtDriverLXC.cc` source file in the repo. Couldn't find that
either.

Where did you get the LXC drivers or are you building LXC drivers from
scratch? I would like to help on this matter, first by testing them and
then to further improve them.

I could use your thoughts on this matter.

Thank you. Cheers and Goodwill,
Valentin Bud
