Quick Post – Network Error Deploying VMware Cloud Director Availability 4.0 Virtual Appliances

Just a quick post covering an issue I discovered when deploying new appliances for the recently released VMware Cloud Director Availability (VCDA) solution (the product formerly known as vCloud Availability).

When I deployed the first management appliance I was a bit puzzled to see this on the console during first power-up (Failed to start vCAv network initializer):


And then when the startup had completed, the console was showing no IP address had been assigned to the appliance:

Which was odd, as I was sure I’d specified the correct IP information during appliance deployment. Logging in to the appliance and looking at the status of the h4network.service showed errors:


The errors appeared to indicate an issue with the MTU network property from the appliance (‘sysboot.extract_ovf_property(Properties, 'net.mtu') in the sysboot.py script. So I did some more digging and tried deploying again with different MTU values, none of which got me any further. I then took a step-back and looked again at the network properties I’d entered for the appliance:


Hands up if you can spot the error before scrolling down for the answer…

In my rush to deploy a shiny new VCDA instance, I hadn’t properly read the information correctly against the ‘Address’ entry:

I’d provided a valid IP address for the appliance, but not what was being asked for – a CIDR address including the subnet mask. After changing the value shown to one appropriate for my network ( in this case) I was able to re-deploy the appliance and the networking came up fine as expected.

Hopefully this will teach me to be a bit more careful in future reading the descriptions for vApp properties when deploying appliances and hopefully will be helpful to anyone else facing the same issue.

    Thanks forr the sensible critique. Me & my neighbor were just preparing
    to do a little research on this. We got a grab a
    book from our area library but I think I learned more clear from this house number sign post

    I am very glad to see such excellent info being shared freely out there.
