Proxmox 5.4-7 no network connection VMs

[GoLuke]

I installed proxmox by a OVH template and I am unable to get a network connection on my VMs
In other installations by OVH template everything worked well without further configurations

The only difference in this new one is the proxmox version. In other installations OVH template used proxomox 5.3-12 on debain 9.8 while now use proxmox 5.4-7 on debian 9.9

It seems that the virtual interface "ens18" on VM does not communicate with the "tap100i0" interface in host.
Configuring a virtual interface on the "host", with the mac address and ip provided by OVH, connected to the bridge i can trace ICMP packets with tcpdump
These packets are not transferred to vm.

Has anyone had the same problem?

There is no solution on this issue. You need to login VM console and setup STATIC ips addresses in your network range availability

Yes, I solved it! I have set the gateway manually on /etc/network/interfaces by post-up option on guest net configuration
because my gateway is in a different subnet.

Thanks!
