I have setup a Debian based hypervisor with a single Ethernet Device, such that /etc/network/interfaces looks like that:
allow-hotplug eth0
iface eth0 inet manual
auto iface eth0.30
iface eth0.30 inet dhcp
auto iface eth0.7
iface eth0.gvlan inet manual
vlan-raw-device eth0
auto br0
iface br0 inet manual
bridge_ports eth0.7
bridge_stp off
bridge_fd 0
bridge_maxwait 0
So, a dynamic IP within vlan 30 for the Hypervisor and a bridge for all the VMs within vlan 7.
The problem is: I can access all services from the VMs and they show up on the router as well. BUT the hypervisor itself is gone. I can neither ping it nor does it show up on the router. Even with sudo nmap -p- 10.10.10.0/24 I cannot see it popping up. How can that happen and is there anything I can do about it?
