vMX

Hi,

 

I am sorry to bother you guys..... I have tried extensive searches on Google to no avail.....

 

I commit the command:

sudo ./vmx.sh -lv --install

 

It all goes really well until the very end where I then get the following:

Assign Management MAC d0:67:e5:ed:eb:90...........[OK]
Add default gw 10.100.7.254.......................[OK]
Create br-int-vmx1................................[OK]
Start br-int-vmx1.................................[OK]
[Failed]
Log file........................................../juniper/vmx/build/vmx1/logs/vmx_1520437727.log
==================================================
Aborted!. 1 error(s) and 0 warning(s)

 

The log files shows the following:

[Command] virsh net-start default
error: Failed to start network default
error: internal error: Network is already in use by interface virbr0

 

I'm almost there.... has anyone seen this before please?

Did you check the documentation:
https://www.juniper.net/documentation/en_US/vmx17.4/topics/task/installation/vmx-install-preparing.html

Note: If you cannot deploy vMX after upgrading libvirt, bring down the virbr0 bridge with the ifconfig virbr0 down command and delete the bridge with the brctl delbr virbr0 command.

I will say great  minds think alike....... I came across this document and apllied before coming back here and it was successful.

 

Thank you for your time 🙂

 

Apologies. I am not going to disturb people with a "simple" new quesiton when it can be related to this issue (kind of)....

 

If I have configured ge-0/0/0 in the config files, is there a reason why this interface will not show up when I type "run show interfaces terse"?

 

Thanks

Why is there no way of deleting asking stupid questions before thinking....... 

 

Ignore the above question. I am really sorry for disturbing you....

 

 

 

It would appear that maybe it's not such a stupid question:

 

I have installed the 60 day license successfully (hence why I thought it was a silly question) and have configred the conf files as per the day one document and also as per another user has configured and still I have no ge-0/0/0 showing under interfaces terse.

I don't think there is anything wrong here .... Has anyone else had this issue please?

As an add on, when I run the following command:

 

sudo ./vmx.sh --bind-dev

 

I get this output:

Warning! Numa node for em1 is unavailable, hence skipping CPU pinning.
[OK]

 

And then when I run  "brctl show", I get the following output:

bridge name              bridge id                            STP enabled                  interfaces

                                                                                                                        vcp-int-vmx1
                                                                                                                        vfp-int-vmx1

vmx_link1           8000.fe060a0efff0                       no                               ge-0.0.0-vmx1

 

This should work, but yet I still have no ge-0/0/0 interface when running show interfaces terse

 

 

 

Okay. I have managed to find a configuration error in the "vmx-junosdev.conf" file where "dev_name : em1" is not possible as it is already being used by "br-ext".... so I have changed this to "dev_name : em3" (also tried em2) .... restarted the vMX, also completed the "sudo ./vmx.sh --bind-dev" command and then completed the "brctl show" command, which gave the following output:

 

bridge name                            bridge id                          STP enabled                          interfaces

                                                                                                                                              em3
                                                                                                                                              ge-0.0.0-vmx1

 

 

Still no ge-0/0/0 interface in "show interfaces terse"

 

 

I would like to open this to say "I know what I did".... but in all honesty I don't know.... all I did was restart the bind-dev and suddenly I have all the ge interfaces showing (although only 0/0/0 is up as it's the only one I have configured)....

 

Apologies that I cannot give a more technical update but that's it.

 

Thank you.
