I've got a Gentoo-based libvirt/qemu-kvm host running with several VMs, |
12 |
also using bridged TAP adapters. It works really well for servers/other |
13 |
"always on" systems that run in the background. virt-manager can handle |
14 |
everything for you, you just have to know the name of the bridge to |
15 |
which you want to the VM to join. |

While that's all true, I personally think 802.1Q VLANs are *much* easier |
34 |
to configure than DHCP and especially DHCPv6. Definitely sysadmin's |
35 |
prerogative, though. |
