openvswitch vs linux bridge

[camaran]

whats the best for performance and setting?

I believe the guidance is to use Linux bridge unless you need features of OVS.

but if i must have e vlan for internal connection for virtual machine ?

You don't need VLAN unless you want to have them or your network requires them. For most things Linux bridge VLAN works fine as well. If you don't know why you need OVS then you probably do not need it.

I run a colorful mix of 10G 802.3ad bond with a 1G NIC in an active-backup bond with a VLAN-aware Linux bridge together with four or five VLANs for the host itself and I have no idea what benefit an OVS would bring me. So, you do the math.

Tried OVS and got a problem with a bond with an LACP link with L3+L4 hashing policy configuration. It didn't work. Linux bond was ok in this configuration:

auto bond0
iface bond0 inet manual
        bond-slaves enp6s0f0 enp7s0f0
        bond-miimon 100
        bond-mode 802.3ad
        bond-xmit-hash-policy layer3+4
