I am new to netplan and Ubuntu 18.04 , and am trying to set up a VM host using qemu/libvert. The issue is with creating a netplan yaml file that meets our needs and works
- Interface eno1 is a management interface. It works fine in the configuration below.
- Interface eno2 will be a dedicated trunk to provide connectivity to the VMs with the rest of the network with a .1Q trunk.
- The interface the VMs will access is a trunk with 4 seperate .1Q tagged vlans.
- Each VM needs direct access to the network using a local IP address (to the VM) assigned to the appropriate bridge/vlan.
- No NAT on the network interfaces of the host.
- As a network engineer, I still belive a "bridge" is Layer 2. No need for an IP address (which also implies traffic will be NAT'ed on the interface)
The bridging/vlan examples at https://netplan.io/examples give me an error message:
Invalid YAML at //etc/netplan/01-netcfg.yaml line 24 column 5: did not find expected key
System details:
- OS: Ubuntu 18.04 LTS
- netplan: netplan/bionic 1.10.1-5build1 amd64
- qemu/kvm: qemu-kvm/bionic-updates,now 1:2.11+dfsg-1ubuntu7.4 amd64 [installed] qemu-kvm/bionic-security 1:2.11+dfsg-1ubuntu7.3 amd64 qemu-kvm/bionic 1:2.11+dfsg-1ubuntu7 amd64
Any help would be appreciated.
