Sub Interfaces in Virl

Noticed that every time got a sub interface configured (have core facing sub interface interface and CE facing sub interface as using a virtual switch for physical topology),  want to run ISIS for the core facing sub interface (which works perfectly fine along with mpls ldp) and ospf as PE to CE protocol on the second sub interface out of the same physical port and ospf never comes up.

Not aware of any support issues regarding OSPF not working out of the sub interface on VIRL.  Would suggest that you check here as this is a more active community support forum for VIRL -> Virtual Internet Routing Lab (VIRL) - The Cisco Learning Network
