Installing IOS XRv 5.2.2 image when I've got XR 5.3.0

Hi there,
Is there a way to have both 5.3 and 5.2 IOX-XR images? I just install the v0.9.17 and I need also 5.2 version. I never
had the previous VIRL so I can't restore the 5.2.2
Thanks,
Remus

Hi @Remus_Grobei - ok, so 1st we need to check the parameter that controls if the download is 'allowed'. If you take a look in the file /etc/virl.ini, you will see a section with the following entries:

## Images
iosv: True
csr1000v: True
iosxrv432: False
iosxrv: True
nxosv: True
vpagent: True
## Not currently available
iosvl2: False

This set of parameters control the operation of the salt-states that will download the images for you, either using the command line as you did in your example, or using the 'VIRL Software' panel in the User Workspace Management interface.

The messages that you've captured occur when the parameter controlling 'iosxrv52' is missing or set to 'False'. This SHOULD be present (so what you're seeing IS a bug) and it should be set to 'True'. We will get this fixed up for the next release!

So how do we solve the problem? Please add the line 'iosxrv52: True' to /etc/virl.ini. Once you've saved the file, run the command 'vinstall salt'. After that command completes, you should be able to either run your command once more (sudo salt-call --master eu-virl-image-server.cisco.com state.sls virl.routervms.iosxrv52), or use the VIRL Software panel to select the XRv 5.2.2 image and start the download.

What you should see is a set of message similar to the following when the image is successfully downloaded and installed:

So, now how do you select the 5.2.2 image to be used instead of the 5.3.0 when you're spinning up a topology?

The salt-call loads the xr 5.2.2 image in to the image database. When you have your network topology in VM Maestro, you need to select the XRv nodes and then set the 'VM image' in the properties tab by pressing the 'Browse' button and selecting the XRv 5.2.2 image from the list. You'll end up with something like:

When you start your simulation, the nodes with the value set with load the specified image - nodes without the value set, will load the default XRv image (5.3.0).

I hope this covers everything!
