## Cloud-Config VMWare Guestinfo Variables
coreos-cloudinit is capable of reading userdata and metadata from the VMware
backdoor. This datasource can be enabled with the `--from-vmware-backdoor` flag.
Userdata and metadata are passed from the hypervisor to the virtual machine
through guest variables. The following guest variables and their expected types
are supported by coreos-cloudinit:
coreos-cloudinit accepts configuration from the VMware RPC API's *guestinfo*
facility. This datasource can be enabled with the `-from-vmware-guestinfo`
flag to coreos-cloudinit.
| guest variable | type |
The following guestinfo variables are recognized and processed by cloudinit
when passed from the hypervisor to the virtual machine at boot time. Note that
property names are prefixed with `guestinfo.` in the VMX, e.g., `guestinfo.hostname`.
