Hello,

after upgrade from latest 5.x to 6.x , VMs on hosts do not have access to network, whole is on ovs bridges, any clue where to investigation ?

Best Regards
 
It could be that your interface names have changed (check with 'ip address', we received multiple reports of this happening on 6.x upgrades). If so, you might have to rename them in your Linux and OVS configuration ('/etc/network/interfaces').

Otherwise, post the output of 'ip address' and your VM config file(s).
 
Hi,

looks like ovs someway not adding interface to vmbr0 properly , there is no physical dev in vmbr0 bridge, but IP is still reachable, when i add manualy enp2s0f0 to vmbr0, the VM's get connection, but whole host network going crazy.

allow-vmbr0 enp2s0f0
iface enp2s0f0 inet manual
ovs_type OVSPort
ovs_bridge vmbr0

auto vmbr0
iface vmbr0 inet static
address 192.168.14.164
netmask 255.255.252.0
ovs_type OVSBridge
ovs_ports enp2s0f0

Hi,

problem was that other interface with vlan starting before this bridge... this works ok with proxmox 5.x and on 6.x i move order of starting interface, topic can be closed.
