| 4 | <title>Configuring Multiple Host-Only Network Interfaces on Oracle Solaris

| 9 | By default Oracle VM VirtualBox provides you with one host-only network
|
|---|
| 10 | interface. Adding more host-only network interfaces on Oracle
|
|---|
| 11 | Solaris hosts requires manual configuration. Here is how to add
|
|---|
| 12 | another host-only network interface.
|
|---|
| 13 | </p>
|
|---|
| 14 | <p>
|
|---|
| 15 | Begin by stopping all running VMs. Then, unplumb the existing
|
|---|
| 16 | "vboxnet0" interface by execute the following command as root:
|
|---|
| 17 | </p>
|
|---|
| 18 | <pre xml:space="preserve"># ifconfig vboxnet0 unplumb</pre>
|
|---|
| 19 | <p>
|
|---|
| 20 | If you have several vboxnet interfaces, you will need to unplumb
|
|---|
| 21 | all of them. Once all vboxnet interfaces are unplumbed, remove the
|
|---|
| 22 | driver by executing the following command as root:
|
|---|
| 23 | </p>
|
|---|
| 24 | <pre xml:space="preserve"># rem_drv vboxnet</pre>
|
|---|
| 25 | <p>
|
|---|
| 26 | Edit the file
|
|---|
| 27 | <filepath>/platform/i86pc/kernel/drv/vboxnet.conf</filepath> and
|
|---|
| 28 | add a line for the new interface we want to add as shown below:
|
|---|
| 29 | </p>
|
|---|
| 30 | <pre xml:space="preserve">name="vboxnet" parent="pseudo" instance=1;
|
|---|
| 31 | name="vboxnet" parent="pseudo" instance=2;</pre>
|
|---|
| 32 | <p>
|
|---|
| 33 | Add as many of these lines as required with each line having a
|
|---|
| 34 | unique instance number.
|
|---|
| 35 | </p>
|
|---|
| 36 | <p>
|
|---|
| 37 | Next, reload the vboxnet driver by executing the following command
|
|---|
| 38 | as root:
|
|---|
| 39 | </p>
|
|---|
| 40 | <pre xml:space="preserve"># add_drv vboxnet</pre>
|
|---|
| 41 | <p>
|
|---|
| 42 | On Oracle Solaris 11.1 and newer hosts you may want to rename the
|
|---|
| 43 | default vanity interface name. To check what name has been
|
|---|
| 44 | assigned, execute:
|
|---|
| 45 | </p>
|
|---|
| 46 | <pre xml:space="preserve">$ dladm show-phys
|
|---|
| 47 | LINK MEDIA STATE SPEED DUPLEX DEVICE
|
|---|
| 48 | net0 Ethernet up 100 full e1000g0
|
|---|
| 49 | net2 Ethernet up 1000 full vboxnet1
|
|---|
| 50 | net1 Ethernet up 1000 full vboxnet0</pre>
|
|---|
| 51 | <p>
|
|---|
| 52 | In the above example, we can rename "net2" to "vboxnet1" before
|
|---|
| 53 | proceeding to plumb the interface. This can be done by executing
|
|---|
| 54 | as root:
|
|---|
| 55 | </p>
|
|---|
| 56 | <pre xml:space="preserve"># dladm rename-link net2 vboxnet1</pre>
|
|---|
| 57 | <p>
|
|---|
| 58 | Now plumb all the interfaces using <userinput>ifconfig
|
|---|
| 59 | vboxnet<varname>X</varname> plumb</userinput>, where
|
|---|
| 60 | <varname>X</varname> would be 1 in this case. Once the
|
|---|
| 61 | interface is plumbed, it may be configured like any other network
|
|---|
| 62 | interface. Refer to the <userinput>ifconfig</userinput> documentation
|
|---|
| 63 | for further details.
|
|---|
| 64 | </p>
|
|---|
| 65 | <p>
|
|---|
| 66 | To make the settings for the newly added interfaces persistent
|
|---|
| 67 | across reboots, you will need to edit the files
|
|---|
| 68 | <filepath>/etc/inet/netmasks</filepath>, and if you are using NWAM
|
|---|
| 69 | <filepath>/etc/nwam/llp</filepath> and add the appropriate entries
|
|---|
| 70 | to set the netmask and static IP for each of those interfaces. The
|
|---|
| 71 | Oracle VM VirtualBox installer only updates these configuration files
|
|---|
| 72 | for the one "vboxnet0" interface it creates by default.
