Description

Github issue: https://github.com/apache/cloudstack/issues/4482

 

NFS Primary Storage mounts are handled by libvirt.

Currently libvirt defaults to NFS version 3 when mounting while it does support NFS version 4 if provided in the XML definition: https://libvirt.org/formatstorage.html#StoragePoolSource

<source>
    <host name='localhost'/>
    <dir path='/var/lib/libvirt/images'/>
    <format type='nfs'/>
    <protocol ver='4'/>
</source>

 
Maybe pass the argument 'nfsvers' to the URL provided to the Management Server and then pass this down to the Hypervisors which generate the XML for libvirt.
