First things first. Citrix ADC at this time isn’t supporting VMware ESX 7.0.1 according to the following article: Support matrix and usage guidelines (citrix.com)
This is something that obviously will get supported in due time. But for the people who are running it just as I am in the lab you would see issues like the ADC instances would lose connectivity or will not load the appropriate network drivers at boot. This is because of the VMXNET3 interface which is causing issues.
Temporary workarounds include just reboot the dam thing until it works… or flip the network interface to E1000 and you have a solid booting/working appliance, well not entirely because the GUI seems to slow down over time to almost not working. I decided to flip it back to VMXNET3 and just do the reboot loop until it works.
Keep in mind that you need to copy/paste your MAC-address before removing the interface and readding them to keep your license etc. nice and working.
Hope it helps!
ESX 7.0 update 1 build 16850804 is supported, anything above is not at this time. I’ve updated my environment to ESX 7.0 update 2 and the same issues are still present.
