In a disaster recovery situation, we struggle to perform the same VLAN networking manually with KVM virt-manager that ONE (5.0) is doing with the 802.1Q network driver.
ONE creates a VLAN-tagged onebr.10 bridge and attaches it to the host’s eno3 interface in trunk mode. Works perfectly.
When I want to do the same thing with virt-manager, I struggle with these questions (see virt-manager procedures):
- What network mode to use : NAT, [[Routed]], [Open], Isolated, SR-IOV pool ? Routed, or Open represents best what ONE is doing ?
- When adding a NIC to the VM, what Network source to use: Bridge (which one), Virtual network, Host device, Specify a shared device name ?
Thank you for any guidance in the disaster recovery situation.
