In the last few days, I’ve been working to build up my home networking lab. I’m using a fairly typical setup nowadays — real Layer 3 switches<\/a> connected to a host machine that runs GNS3<\/a> as well as VirtualBox<\/a>. Having recently installed Vyatta<\/a> and Mikrotik RouterOS <\/a>VM guests, I decided that I would play with something I’ve never touched before — Juniper’s JunOS<\/a>.<\/p>\n

\"JuniperNetworks\"<\/a><\/p>\n

The documentation for how to install JunOS into a Qemu environment is constantly replicated across the web, so I have no intention of doing so here. (Have a look here<\/a> to get yourself started). In my first few attempts to create a VM guest, I followed the instructions thoroughly, but eventually I opted to move the full creation into VirtualBox. That’s when I learned a lot about the nuances between installing on either platform.<\/p>\n

One of the first problems I encountered when trying to install into a VirtualBox container was an odd out-of-space message when installing my modified version of JunOS 8.5R1.14 :<\/p>\n

WARNING: The \/tmp filesystem that is created by the next stage of
\nWARNING: the installer does not have sufficient space. This package
\nWARNING: requires 159804k free (2k for configuration
\nWARNING: files and 159802k for the new software), but there is
\nWARNING: only -12140k available.<\/p><\/blockquote>\n

What makes this message odd is that I have plenty of disk space. It’s also odd that I only encountered this in my VirtualBox\/vdi installations, not on Qemu\/qcow2 installations. Before I dug any further, I rebuilt the VM using 10G of storage instead of the recommended 4G, and adjusted each of the individual partitions accordingly. This proved to be ineffective as I was once again greeted with this message.<\/p>\n

The warning message is generated by the function “tmp_storage()” in the +REQUEST file inside\u00a0jinstall-8.5R1.14-domestic.tgz. One of the expr calls is failing, but I never bothered to dig into why and instead removed it with a quick patch<\/a>. The bootstrap installation now appears to be good and will prompt you to reboot.<\/p>\n

At this point, ensure that you have serial port 1 redirected to a host pipe. If you don’t, shut down the VM and add one — you will need it to see what’s going on.<\/p>\n

\"Serial<\/a>
No need for a fancy schmancy DB9 connector<\/figcaption><\/figure>\n

You can attach to the host pipe a few different ways, I prefer to have socat<\/a> connect to it and create a \/tmp\/juniper0 PTY that I can hook into from minicom. Do keep in mind that socat doesn’t respawn automatically, so if you disconnect from the PTY link you may have to restart socat.<\/p>\n

socat UNIX-CONNECT:\/tmp\/juniper_serial PTY,link=\/tmp\/juniper0,raw,echo=0,waitslave<\/p><\/blockquote>\n

Upon reboot,\u00a0 the system would now install up to a point and then hang. After a few moments it was obvious something<\/strong><\/em><\/span> didn’t give.<\/p>\n

A few reboots later I realized that this was going nowhere. Since my test build in Qemu alone\u00a0did<\/span><\/strong><\/em> install, I opted to simply convert the qcow2 file to something I could import into VirtualBox<\/a>.<\/p>\n

qemu-img convert -O raw ~\/GNS3\/QEMU\/olive-base.img JuniperBase.raw<\/p>\n

VBoxManage convertdd JuniperBase.raw JuniperBase.vdi<\/p>\n

VBoxManage modifyvdi JuniperBase.vdi compact<\/p><\/blockquote>\n

However this caused an interesting bug: Prior to installing JunOS, packet captures on the guest indicated that OSPF all-router multicast messages were entering the guest VM. After installation, that was no longer the case. I tried numerous times to resolve this, but with no luck.<\/p>\n

Finally I opted to build a 4.11 FreeBSD instance and install Junos 9.6R1.13. My first attempt failed with the following message:<\/p>\n

ELF binary type “0” not known<\/p><\/blockquote>\n

If you see this message, make sure that you’ve properly replaced checkpic with \/usr\/bin\/true. <\/a>In my case, I had accidentally just copied true to the directory and didn’t replace checkpic. After fixing my mistake, the bootstrap installation succeeded and prompted me for a reboot.<\/p>\n

After reboot the full install commences. I was quite surprised when it completed without any problems. I was skeptical that this was going to fix the multicast problem, but lo and behold, post reboot multicast actually functions.<\/p>\n

\"OSPF<\/a>
Low and behold – it works!<\/figcaption><\/figure>\n

So in the end, my working VirtualBox JunOS instance consisted of FreeBSD 4.11, JunOS 9.6R1.13 and VirtualBox 4.2.12 r84980.<\/p>\n
