I have two kind of hosts:
* some with default ovirt node 4.4 kernel settings
* some with custom kernel settings including intel_iommu=on
I can't open vm console from the second category host when binding from
a different vlan because the host is unreacheable
But if I set sysctl -w net.ipv4.conf.all.rp_filter=2, I can bind the
host and open a vm console.
I didn't test if this behaviour is because of Hostdev Passthrough &
SR-IOV or Nested Virtualization.
Is it an expected behaviour or a bug?

I'd only hazard that the pass-through virtualization settings have zero effect on
anything network, unless you're actually running a nested VM.
SR-IOV would be an entirely different issue if that is actually used and not just enabled.
