vagrant ssh
### Start PBot VM Guest Server
sudo guest-server
Some distributions may require you to specify the full path:
sudo /usr/local/bin/guest-server
### Start PBot VM Host Server
After starting the guest-server, you must now start the host server.
../host/bin/vm-server
### Test PBot VM
In your instance of PBot, the `sh` and `cc`, etc, commands should now produce output:
<pragma-> sh echo Hello world!
<PBot> Hello world!

and then make a new directory, e.g. FreeBSD-14, and copy one of the existing PBot-VM Vagrantfiles into
this directory, and then edit the `config.vm.box` line to point at the chosen OS/distribution, e.g. `freebsd/FreeBSD-14.0-CURRENT`.
Some boxes may have specific settings that you may need to copy over. To obtain and examine the box's Vagrantfile:
vagrant init <OS/distribution>

as `root` and run `shutdown now -h`. Then run `virsh start pbot-vm`. (Using `shutdown now -r` to reboot
will not initialize the new serial/vsock devices.) Login as `root` when the virtual machine boots back up.
### Install software
Now we can install any software and programming languages we want to make available
in the virtual machine. Use the `dnf search` or `zypper se` command or your distribution's documentation
to find packages. I will soon make available a script to install all package necessary for all
languages supported by PBot.
To make use of VM sockets, install the `socat` package:
Fedora:
guest$ dnf install socat
OpenSUSE Tumbleweed:
guest$ zypper in socat
For the C programming language you will need at least these:
Fedora:
guest$ dnf install libubsan libasan gdb gcc clang
OpenSUSE Tumbleweed:
guest$ zypper in libubsan1 libasan8 gdb gcc clang
Install packages for other languages as desired.
### Install Perl
Now we need to install Perl on the guest. This allows us to run the PBot VM Guest server
script.
Fedora:
guest$ dnf install perl-interpreter perl-lib perl-IPC-Run perl-JSON-XS perl-English perl-IPC-Shareable
OpenSUSE Tumbleweed:
guest$ zypper in perl-IPC-Run perl-JSON-XS make gcc
guest$ cpan i IPC::Shareable
This installs the minium packages for the Perl interpreter (note we used `perl-interpreter` instead of `perl`),
as well as a few Perl modules.
### Install PBot VM Guest

and the physical host system. We'll do this inside the virtual machine guest system, logged on as `root`

scripts are available, it will warn you to manually install the packages for the `cc` languages
you want to use. You may use `./guest/provision/tumbleweed` as a reference.
to run any provisioning scripts from the [`./guest/provision`](../applets/pbot-vm/guest/provision) directory.
After running the `setup-guest` script, we need to make the environment changes take effect:
guest$ source /root/.bashrc
We no longer need the `/tmp/guest/` stuff. We can delete it:
guest$ rm -rf guest/
### Install software
If you received the message `!! No provisioning script available for $OS. Install packages manually. !!`,
you must manually install any software and programming languages you want to make available
in the virtual machine. To do so, follow one of the [PBot VM provisioning scripts](../applets/pbot-vm/guest/provision/) as a guide.
