vCenter 6.7 Appliance keeps losing its default gateway

[DefenderAtkins]

Hi all,

I have deployed a vCenter 6.7 Appliance into my current vSphere as I want to migrate my Windows vCenter Server 5.5 to 6.5 Appliance and onto 6.7 Appliance ( I know there is no direct upgrade path to 6.7 from 5.5).

So anyway I've deployed it as a VM in the current vSphere managed by vCenter Server 5.5, all was well, logged into web client and configured it, joined the domain, etc.

However, the next day I couldnt connect to it so I had a look in the console and found that it doesnt have a default gateway. I added the default gateway manually and saved it but as soon as I clicked Y to save the network configuration, the gateway disappears.

The only way to make this work is to remove the NIC from the VM and add it back in. This will work for about 5 minutes and then the gateway disappears again.

IP, subnet and gateway are correct. There are other machines in that network without an issue.

Any ideas?

For anyone that finds this and has the same issue, I got around it by removing the NIC and readding it as an E1000.

Can you deploy the VCSA 6.7 on atleast an ESXi 6.0 and check if the same behaviour persists.

Interesting bug, hope this is resolved soon as it interrupted the deployment. The work around did work however. Thanks!

In my case I had to manually edit the network config file.

/etc/systemd/network
