Hi,
I am using ESXi 6.5.0 Build 5310538 to deploy a Tiny Core Linux 10.0 (64bit) guest. Since Tiny Core Linux is not in the list of available operating systems, we used to select Other (Other 64bit) option. All the previous ESXi version we are using does not show a warning with that configuration. But ESXi 6.5.0 show the below warning.
"The configured guest OS (Other (64-bit)) for this virtual machine does not match the guest that is currently running (Linux 4.19.10-tinycore64 TinyCoreLinux 10.0 ). You should specify the correct guest OS to allow for guest-specific optimizations."
The same warning is shown when Linux Other Linux 64bit option selected.
My understanding is since VMWare does not have the Tiny Core Linux option it should not show a warning when Other (Other Linux 64bit) option selected.
