  • 1.  vMX on Ubuntu 16.04 LTS

     
    Posted 12-06-2018 03:14

    Hi,

     

    I have installed Ubuntu 16.04 because I need to install vMX version 18.3 and have gone through the configuration process prior to running the following command:

     

    sudo ./vmx.sh -lv --install

     

    I have added , whatI believe to be a required line, to the vmx.conf file as follows:

    device-type : virtio
    identifier : vmx1 
    host-management-interface : eno2
    routing-engine-image : "/home/clive/juniper/images/junos-vmx-x86-64-18.3R1.9.qcow2"
    routing-engine-hdd : "/home/clive/juniper/images/vmxhdd.img"
    forwarding-engine-image : "/home/clive/juniper/images/vFPC-20180829.img"

     

    And running the command:

     

    sudo ./vmx.sh -lv --install

     

    Halts at the following error (almost immediately):

     

    ==================================================
    Welcome to VMX
    ==================================================
    Date..............................................12/06/18 11:06:50

    ./vmx.sh: 82: [: virtio: unexpected operator
    Error! Invalid virtio

     

    Any ideas as to why please? I have tried commenting out the line....

     

    I have no problem at all on Ubunti 14 LTS for vMX 17   ----  but I really need vMX 18.3

    Hi,

     

    Can you please share the complete file of vmx.conf.

     

    i think this a syntax issue, can you try the same by modifiying a sample config file, which would under "config/samples/".

    Sure... here's the vmx.conf file (currently):

    We dont need device-type configured under HOST section.. It has been already defined under vPFE section.. 

    So can you remove device-type under HOST section and try.

    How weird. I actually hashed that line out and tried and it still failed, but if you remove the line completely it gets past that point.

     

    Okay, now I'm stuck here:

    sudo ./vmx.sh -lv --install

    I think that may be because of this error I get when I complete the following command:

     

    sudo apt-get install libnl-dev

     

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    Package libnl-dev is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    E: Package 'libnl-dev' has no installation candidate

     

    Nope: I've fixed that error by using:

     

    sudo apt-get install libnl-3-dev

     

    Same failure error though:
