Please note: All Linux and HP-UX sample commands in this section are performed as the root user (prompt = #). This may not be necessary for all commands in all environments depending on the local permission settings. The commands can be executed on the Charon host graphical console or via a non-graphical login (e.g., SSH). However, for accessing the running emulator, the use of PuTTY is strongly recommended because it works best with the emulator environment.

The Charon-PAR/PA9-32 functionality of Charon-PAR emulates historic 32-bit PA-RISC hardware. This section shows a sample installation of a 32-bit guest system.

Creating a Virtual Disk Container for the System Disk

...


StepCommand
1Change to the directory where you store your virtual disks.# cd /data/Stromasys/host1/Data/Disk/
2

Create an empty disk container. Note that the actual size of the disk will depend on the requirements of your emulated system. The disk name shown is just an example.

Please note: HP-UX 9.07 allows a maximum root disk size of 2GB. The number of blocks should be a multiple of 512.

With dd:

# dd if=/dev/zero of=ldev1.dsk bs=1K count=2091520


With fallocate (very fast alternative):

# fallocate --length 2147483648 ldev1.dsk
Please note: the size of the disk must be such that it is aligned to a 512-byte boundary. You can check this with the following bash expression:
$ bytes=<number-of-bytes>; echo $(( bytes - bytes/512*512 ))
If it returns 0, the alignment is correct.

Adapting the Configuration File Template

The configuration file template must be adapted to the customer environment and the required guest system characteristics. This section describes the minimum number of changes required to configure a Charon-PAR/PA9-32 emulator instance. Please refer to Configuration File Reference for a detailed description of the configuration file options.

...


StepDescription
1Create a copy of the configuration file template.

Example: 

# cd /data/Stromasys/host1/

# cp /opt/charon/cfg/pa9-32.cfg host1.cfg

2Open the configuration file in a text editor.

# vi host1.cfg

or

# gedit host1.cfg

3Configure the system model.

model "720"

Configured model must be covered by your license.

4Configure the RAM for the emulated system (in MB).memory 64
5Configure the serial console for telnet via PuTTY.

Use the method 2 of the serial line section in the configuration file and make sure the definition of the asp.uart0.device is:

asp.uart0.device.command="putty -load PAR-Telnet-VT100"

6Configure disk 1 (system disk).

Change definition of DKA0 to:

DKA0.image="/data/Stromasys/host1/Data/Disk/ldev1.dsk"

7Add a definition for disk 2 (ISO file) or (if it already exists) modify the definition to point to your ISO installation file for the mini-system (the install disk).

load DKA100

DKA100.image="/data/Stromasys/host1/Data/Disk/HP-UX_9.07_Install_S700.iso"

8Configure a network card based on a physical host NIC. This NIC is dedicated to the guest operating system and cannot be used for network communication by the host system. To share an interface, a virtual bridge would have to be used (see Ethernet configuration sections in this document).

In the configuration file template, comment out the dummy interface and the tap interface configuration. Then uncomment the interface configuration of the physical interface example. Change the definition of EWA0 to the interface that is assigned to the emulated system (example: eth1) and disable the offload parameters for the interface:

system.lan0.card.mapping_mode="RAW"

system.lan0.card.iface="eth1"

system.lan0.card.initialize_command="ethtool -K $IFACE rx off ; ethtool -K $IFACE tx off ; ethtool -K $IFACE sg off ; ethtool -K $IFACE gso off ; ethtool -K $IFACE gro off ; ethtool -K $IFACE txvlan off ; ethtool -K $IFACE rxvlan off"

Please note: Depending on the capabilities of the Ethernet device, not all offload parameters maybe be available. This will create a warning message. The variable IFACE is set by the system before executing the initialize command.

For cloud environments, please note:

  • The MAC address on an interface must be the same as the one configured by the cloud provider on the dedicated interface. This should be the case by default for Charon-PAR. The IP address used by the guest OS must be the one configured by the cloud provider.
  • Virtual bridge configurations that are linked to a host NIC are not possible in cloud environments. Only "internal virtual bridge" configurations are possible. Such bridges can be used for host-guest communication. External communication for the guest can be achieved either by NAT or by routing configurations (depending on requirements and cloud-specific restrictions). A less complex, TAP based solution is to use a MACVTAP interface (using MAC and IP address assigned by the cloud provider).
9Save the configuration file.

Starting the Emulated System and Installing the Guest System

...

Starting with Charon-PAR version 3.0.5 this will, by default, automatically stop the emulator when it detects that the operating system has been halted. See the system.stop_on_halt parameter in the Configuration File Reference. If the emulator is not stopped automatically, continue with step 2 below.
