• On a Charon-SSP AWS host, you can either use an internal bridge to create TAP interfaces that will then be used in the emulator configuration, or you can use a dedicated NIC. If a dedicated NIC is used, the MAC address of the emulated interface must be set to the MAC address of the NIC connected to the Charon host and the IP address of the guest system must be set to the private IP address allocated to the NIC by AWS.

• It is permitted to assign the localhost interface (lo) to an emulated device (if the device will not be used by the guest).It is also permitted to add only a dummy device is required in the guest).

• Some options are configurable, but will not work in the AWS environment. They are listed here only for completeness:

  • Using the same physical device

  to

  • for multiple emulated Ethernet devices of the same instance.

  However, this is not recommended for performance reasons.

  • Sharing a NIC between emulator and host

  (not recommended for performance reasons) is possible on non-cloud systems but requires promiscuous mode and the MAC addresses of host and emulated system to be different (normally this is automatically taken care of by Charon-SSP assigning a locally administered MAC address to the guest system)

  • .

  • Assigning the same physical interface to more than one Charon-SSP instance

  is possible on non-cloud systems but not supported for production operation

  • .

  It requires promiscuous mode and manual setting of unique MAC addresses for the Charon instances. I/O performance will be significantly degraded. For testing purposes only. 

Set MAC Address:

To force the MAC address of the virtual Ethernet device to a specific value, select the checkbox and enter the address in groups of two-character hexadecimal digits, separated by a colon, e.g. 08:00:2b:aa:bb:cc.
