Cumulus ignite runtime error

[michelredondo]

Hi,
while running a clab topo with cvx nodes (ignite runtime), this error appears:

Is there any limit on the number of interfaces supported on the ignite runtime?

paging @networkop

Thanks!

[networkop]

AFAIK, there's no ignite-specific limit. Sounds like some hardware or OS limitation. what sort of environment are you running on?

[michelredondo]

Done!!

[networkop]

Thanks @michelredondo. Do I now need to build an image and push it to networkop/ignite:dev ?

[michelredondo]

yes, that's my understanding. Clab will pull it:

containerlab/nodes/cvx/cvx.go

Line 19 in 582f76a

defaultIgniteSandboxImage = "networkop/ignite:dev"

[networkop]

all done from my side 👍

[michelredondo]

tested and working!

The additional steps for users that already have used ignite is to delete the existing docker image (docker image rm networkop/ignite:dev) and also delete firecracker folder (rm -rf /var/lib/firecracker/) so image import is triggered with new topology deployment.

paging @hellt in case he considers that additional knobs are needed.

Thanks @networkop
