## Symptoms

- * Changing interfaces configuration on ESX Virtual Machine running Gaia OS does not survive reboot.

  <br />

* `/var/log/messages` file shows the following:

  ```
  
  xpand[PID]: NETIS Message:Problem occured during installing new IP on interface ethX
  xpand[PID]: NETIS Message:netis_netif_link_set_ip : Configuring IPv4 address for ethX Failed
  xpand[PID]: NETIS Message:netis_netif_selective_link_reconf : Configuring IP addresses for ethX Failed
  xpand[PID]: netis_conn_* failed eth0 -5
  ```

## Cause

* VMXNET3 network adapter is supported by Security Gateway VE in Network mode:  
  * Starting from R77 it is included in the OVF Template only.
  * Starting from R77.30 it is included in the ISO and in the OVF Template.
* VMXNET network adapter is *not* supported.

## Solution

Configure "e1000" network adapter in ESX Virtual Machine properties.
