What is cloudboot?
Cloudboot refers to a type of Compute Resource (HV) which is booted from an image generally hosted on the Control Panel server. Cloudboot HVs are required for the use of OnApp Integrated Storage.
Since these are booted from an image, some configurations will not be saved between reboots. However, you can use "Custom Config" to effectively save configurations. The custom config executes as a script on the HV any time it is booted.
