I'm in a bit of a pickle here.

I have a bunch of Ubuntu 22.04 VMs, hosted on multiple ESXi servers.

When I try to apply netplan using netplan apply, system networking freezes and no packets are sent (checked with tcpdump).

Also, when I try to install systemd-timesyncd and enable ntp service, same thing happens.

I've tried different things, including tweaks on keepalived parameters in kernel, but no luck so far...

Any ideas why this happens?

Netplan config (as per Artem's comment)

network:
  version: 2
  ethernets:
    ens160:
      dhcp4: no
      dhcp6: no
      optional: true
      match:
        macaddress: "00:50:56:94:c2:1a"
      addresses:
      - 172.16.96.31/20
      nameservers:
        addresses:
        - 172.16.1.3
      routes:
      - to: 0.0.0.0/0
        via: 172.16.1.3
        on-link: true
      - to: 172.16.1.0/24 
        via: 172.16.111.254
      - to: 172.18.0.0/16 
        via: 172.16.111.254
      - to: 172.16.53.104/32 
        via: 172.16.111.254
      - to: 172.16.8.0/24 
        via: 172.16.111.254
      - to: 172.16.56.0/24 
        via: 172.16.111.254
      - to: 172.16.96.0/20 
        via: 172.16.111.254
      - to: 172.16.49.0/24 
        via: 172.16.111.254

P.S 1: I added match to point out to the exact MAC Address on my network interface as part of my efforts, but it didn't solve the problem.
