I believe your problem is in your definition of bond0
~~~
auto bond0
iface bond0 inet manual
    bond-members eno1 eno2
~~~

Bond members here should be eno1 and eno2, and not nic1 nic2
Looking at the eno3 nic, you have done the same problem nic3 should be eno3

~~~
auto eno3
iface eno3 inet static
    address 10.0.300.100/24
~~~

Another problem I see with your configuration is that you define 
gateways on each vlan interface. Linux only have one routing domain.
Remember that you don't need either gateway nor ip address on the bridge 
you use for vm's.
