Hi,

I have a CentOS7 host with libvirt, attempting to boot a CentOS7 guest. I am attempting to do the install over ipv6 (because why not).

I have the following network configuration.

Cisco 3550 gi0/1 <-> eno1 (CentOS7) host.

gi0/1 is configured as:

switchport trunk encapsulation dot1q switchport trunk allowed vlan 1-17
switchport mode trunk

Mainly in question is vlan11 as this is the network I am trying to work with.

The switch have vlan11 configured with STP:

# sh spa v 11
VLAN0011
