vMX installation failure

[ Edited ]

Hi,

 

I have installed Ubuntu Server 14.04 as per Juniper recommendations and am now in the process of installing the vMX. I have hit a bit of a wall here as follows:

 

The vMX package I have been supplied is: vmx-bundle-17.4R1.16.tgz ..... As I don't have access to download from Juniper it has been supplied by our hardware suppliers. The file size is 3.928 gig.

 

I have configured Ubuntu for kvm installation as per recommendations and that is all okay.

 

So, I then unpack the tar file with: tar xzvf vmx-bundle-17.4R1.16.tgz.

 

Navigate to /tmp/vmx .... 

 

Here is where I have the problem...... I cannot complete the installation because the "images" directory has nothing in there that resembles the requirements for the vmx.conf file...... My images file just contains "metadat-usb" images and not the required "jinstall" etc as per the following document:

https://www.juniper.net/documentation/en_US/vmx14.1/topics/task/configuration/vmx-instance-configuri...

 

It's almost like I have not got the required files....

What is the md5 for the "vmx-bundle-17.4R1.16.tgz" file.

Share the "ls -lrt" output of image folder..

 

You should have below files:

root@ubuntu:/var/tmp/vmx-16.1R5.7/images# ls -lrt

Hi,


As the machine is completey separate I cannot simply show the files. What I can say is that when I run ls -lrt on the images directory under vmx the total = 6613136 and the files included are the same as what you have mentioned.

 

So, it would seem that the files are there.... but why does vmx.conf call completely different files? It will never install while vmx.conf is calling files that don't exist.


Thanks

Hi,

 

You need to modify the vmx.conf file with relavant path of images files and then allocate the vCPU's,memeory & ports.

 

HOST:
identifier : vmx1 # Maximum 6 characters
host-management-interface : em1
routing-engine-image : "/var/tmp/vmx-16.1R5.7/images/junos-vmx-x86-64-16.1R5.7.qcow2"
routing-engine-hdd : "/var/tmp/vmx-16.1R5.7/images/vmxhdd.img"
forwarding-engine-image : "/var/tmp/vmx-16.1R5.7/images/vFPC-20170802.img"

 

 

Please refer below Dayone book for vMX

Hi Vishruth,

 

Thank you for the information. I have changed the relevant paths and it is installing but with other errors now. But that's cool.... the errors are just missing modules which I can work through. There are about 7 missing modules but I can get those through apt-get......

 

Again, thank you....

Hi,


A quick add on to this if I may please:

 

I have a missing module called "netifaces"...... I am guessing this is becasue ubuntu server 14.04 utilises python 2.7.6 .... I can find the help for Python3 for module netifaces but nothing for 2.7.6.....

 

My question is: Is it safe to install Python3 or are you guys using python 2.7.6 and managed to get this working using what process please?

I have managed to get around this issue by performing the following on Ubuntu 14.04 (for anyone that may be stuck at this point):

 

sudo apt-get install python-dev   ..... This installs the required GCC Modules..... then completed:

 

sudo pip install netifaces
