SUMMARY
Unable to find suitable platform type
ISSUE
On creating a Protection Group, some of VMs may have red 'x' icons and the message says "unable to find suitable platform type for XXX". Boomerang only supports VMs with supported guest OS running, and those with non-supported guest OS cannot be included in a Protection Group. Please see this document for the list of supported guest OS.
RESOLUTION
If you have encountered this error but the actual guest OS running in the VM is in the supported list, please read this document to update the configuration of the VM.
