Problèmes réseau après migration vm

[Romtrid]

Bonjour,
après chaque migration des mes vm il y a un problème de réseau. Soi c'est un problème de configuration réseau de mes hyperviseurs soit un problème de ma vm. Mais la je suis totalement bloquée. Surtout que c'est un peut gênant pour des vm HA qui doit rendre un service de 99.99
Merci pour une réponse rapide.
Cordialement

Could you post your network configuration /etc/network/interfaces?

Hello,

My config of /et/network/interface (pve1) :

iface eno4 inet manual

allow-vmbr0 eno3
iface eno3 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr0

# Network IP WAN

allow-ovs vmbr0
iface vmbr0 inet static
        address  51.X.X.219
        netmask  24
        gateway  51.X.X.254
        ovs_type OVSBridge
        ovs_ports eno3

# Network VM

auto vmbr1
iface vmbr1 inet static
        address  10.0.0.254
        netmask  20
        bridge-ports eno4
        bridge-stp off
        bridge-fd 0

My config of /et/network/interface (pve2) :

iface eno4 inet manual

allow-vmbr0 eno3
iface eno3 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr0

# Network IP WAN
allow-ovs vmbr0
iface vmbr0 inet static
        address  51.X.X.218
        netmask  24
        gateway  51.X.X.254
        ovs_type OVSBridge
        ovs_ports eno3

# Network VM
auto vmbr1
iface vmbr1 inet static
        address  10.0.0.253
        netmask  20
        bridge-ports eno4
        bridge-stp off
        bridge-fd 0

My config of /et/network/interface (pve3) :

iface eno4 inet manual

allow-vmbr0 eno3
iface eno3 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr0

# Network IP WAN
allow-ovs vmbr0
iface vmbr0 inet static
        address  51.X.X.217
        netmask  24
        gateway  51.X.X.254
        ovs_type OVSBridge
        ovs_ports eno3

# Network VM
auto vmbr1
iface vmbr1 inet static
        address  10.0.0.252
        netmask  20
        bridge-ports eno4
        bridge-stp off
        bridge-fd 0

the connection between the clusters is done via OpenVPN (network 10.0.20.0/29)


But following the migration the VM no longer has a network.

I do not understand what I have to do as a network configuration

What is your vm gateway ?
