Use virtiofs in KVM virtual machines

Product Support Installation & Configuration

Hello.

Does someone try to configure virtiofs in OpenNebula virtual machines?

It looks like I can only do that with RAW/DATA :thinking:

Looks like it Daniel :wink:

Let me ask the team to see if we can give you a proper answer

Cheers,

Thanks.

For information, the use case is sharing some space between VMs, like the RWx volumes in kubernetes since we have a MooseFS storage.

I thought about a dedicated DS_MAD and TM_MAD to automatically provision a new storage space (a directory) in our MooseFS when creating a “disk” and linking it to the running VMS but I don’t think a “disk” can be multi-attached, right?

The next challenging thing is to build the right libvirt domain snippet but I don’t if OpenNebula is pluggable enough for that.

You’d probably missed the PERSISTENT_TYPE in the image attributes :wink:

BR,

The problem of using OpenNebula for foo long, I did not catch all the new features and missed that one from 6.0. Or more probably, I noticed it, enjoyed it and forgot.

Thanks, I then I create a datasore with a custom DS, setting that PERSISTENT_TYPE and looking how to set the dir source type, this should avoid my needs for virtioFS.

Thanks a lot for the reminder, I’m quite sure I just forgot since that exactly what we need :wink:
