2. Setup Guests

Important

Always start RTOS as first guest, as this will create the initial instance of RtosVnet!

2.1. Host

No setup required, as this guide uses the default IP address (192.168.157.1) of the Host.

2.2. RT-Linux

No setup required, as this guide uses the default IP address (192.168.157.2) of the RTOS.

2.3. Linux I (UBUNTU)

2.3.1. Linux I Host-side guest configuration

Attention

This changes must be done on the Host side for the Linux (UBUNTU) guest!

Open configuration script of vm1 and edit the rtosvnet_nw value.

cd /hv/VMs/vm1
gedit ./vmconfig.sh

Search the following line:

# Private RtosVnet network between RTOS and GP-OS
export rtosvnet_nw=0

and change it to:

# Private RtosVnet network between RTOS and GP-OS
export rtosvnet_nw=1

Hint

Changes to the other values of the RtosVnet config section only needed if different IP ranges or names are required!

2.3.2. Linux I Guest-side configuration

Attention

This changes must be done in running Linux (UBUNTU) guest!

Caution

To start the Linux I (UBUNTU) guest with a loaded RtosVnet instance, the Rtos (RT-Linux) must be started before!

  • start RT-Linux

cd /hv/lx
sudo ./lx.sh
./dbgcon.sh

  • start Linux I (UBUNTU) guest

cd /hv/VMs/vm1
sudo ./vmrun.sh

Switch into UBUNTU guest and goto Settings -> Network and edit the ens10 adapter.

Goto IPv4 tab and edit the following values:

  • IPv4 Method: manual

  • Address: 192.168.157.10

  • Netmask: 255.255.255.0

2.4. Linux II (UBUNTU)

2.4.1. Linux II Host-side guest configuration

Attention

This changes must be done on the host side for the Linux (UBUNTU) guest!

Open configuration script of vm2 and edit the rtosvnet_nw value.

cd /hv/VMs/vm2
gedit ./vmconfig.sh

Search the following line:

# Private RtosVnet network between RTOS and GP-OS
export rtosvnet_nw=0

and change it to:

# Private RtosVnet network between RTOS and GP-OS
export rtosvnet_nw=1

Hint

Changes to the other values of the RtosVnet config section only needed if different IP ranges or names are required!

2.4.2. Linux II Guest-side configuration

Attention

This changes must be done in running Linux (UBUNTU) guest!

Caution

To start the Linux II (UBUNTU) guest with a loaded RtosVnet instance, the Rtos (RT-Linux) must be started before!

  • start RT-Linux (if not yet started!)

cd /hv/lx
sudo ./lx.sh
./dbgcon.sh

  • start Linux II (UBUNTU) guest

cd /hv/VMs/vm2
sudo ./vmrun.sh

Switch into UBUNTU guest and goto Settings -> Network and edit the ens10 adapter.

Goto IPv4 tab and edit the following values:

  • IPv4 Method: manual

  • Address: 192.168.157.11

  • Netmask: 255.255.255.0

2.5. Final IP configuration

  • Host: 192.168.157.1

  • RT-Linux: 192.168.157.2

  • Linux I (UBUNTU): 192.168.157.10

  • Linux II (UBUNTU): 192.168.157.11
