There's no point in having them in two different subnets if they're in the same network and vlan, the traffic isn't isolated at all. You might as well have them in the same subnet if you're doing that, in which case you only need 1 IP on the XCP-ng management NIC.

I just wonder is it possible or not...

You'd want to add another NIC/interface to this VM and then assign that to the other subnet/VLAN.

Normally speaking you wouldn't have multiple subnets/IPs on a single virtual NIC, the best route to go is to add another NIC and assign IPs on that end.

What is your goal here?

I have storages on 2 different ip blocks. 1 for NFS 1 for ISCSI...

It's not recommended anyhow, why do you need to assign another subnet to an adapter already in a different subnet? These should typically be isolated either physically via different connections, or via VLANs.

I want to add second ip address to existing interface.

Example how can i add 10.1.2.100/24 to eth3.

Do you mean adding a new extra virtual NIC to XO VM?
