Hi, You can use any version. They differ only in approach to handle snapshots and clones. Please note that in v2 a garbage collector, that is required for this version, is not implemented yet.
Thank you.

Hi. Please try to restart xen-api using xe-toolstack-restart command on your XenServer host. The error message that you received means that xen-api didn't load RBDSR plugin. It's not about the rbd kernel driver. Please check the /etc/xapi.conf file. If you installed RBDSR using install.sh script then /etc/xapi.conf should have 'rbd' in 'sm-plugins' parameter.
