Hi Fuzail, 

Even there are  8 VFs in total, you only specified 2 in the hostnet network. 
And connections='2' means the hostnet networks is connected 2 times, so both of the 2 VFs in hostnet are occupied.
Please try to define network like this:
<network>
  <name>hostnet</name>
  <forward mode='passthrough'  managed='yes'>
<pf dev='ens2'/>
</forward>
</network>
It will include all the 8 VFs from PF ens2.

I'd just like to point out that 2.0.0 is very old libvirt, even debian 9 has
3.0.n, can you verify you're experiencing the same kind of issue with the
current upstream?
