## VMware ESXi
---

As of v1.1.0, RancherOS automatically detects that it is running on VMware ESXi, and automatically adds the `open-vm-tools` service to be downloaded and started, and uses `guestinfo` keys to set the cloud-init data.

### VMware guestinfo

| GUESTINFO VARIABLE |	TYPE |
|---|---|
| `hostname |	hostname |
| `interface.<n>.name` |	string |
| `interface.<n>.mac` |	MAC address (is used to match the ethernet device's MAC address, not to set it) |
| `interface.<n>.dhcp` |	{"yes", "no"} |
| `interface.<n>.role` |	{"public", "private"} |
| `interface.<n>.ip.<m>.address` |	CIDR IP address |
| `interface.<n>.route.<l>.gateway` |	IP address |
| `interface.<n>.route.<l>.destination` |	CIDR IP address (not available yet) |
| `dns.server.<x>` | IP address |
| `dns.domain.<y> |	DNS search domain` |
| `cloud-init.config.data | string` |
| `cloud-init.data.encoding` |	{"", "base64", "gzip+base64"} |
| `cloud-init.config.url` |	URL |

> **Note:** "n", "m", "l", "x" and "y" are 0-indexed, incrementing integers. The identifier for an interface (`<n>`) is used in the generation of the default interface name in the form `eth<n>`.
