Centos 7 VM Network not working

[lps90]

Proxmox 7
Centos 7 VM
OVH Dedicated server

Hi guys
I just installed a Centos 7 vm, added a static ip and deactivated centos firewall.
I still cant ping the public network (ping 8.8.8.8 / ping google.com).
Anyone can tell me what could be the problem?

Regards

hi,

from the VM:
* can you ping your PVE's address?
* can you ping your router/gateway?

how is your network in the VM set up? please show us the network configuration and the VM configuration (qm config VMID from PVE)

and also your PVE's network configuration (/etc/network/interfaces)

Hi, i recently switched from bridged network to routed network. My interfaces file at host is:

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

source /etc/network/interfaces.d/*
