vJunos-switch default user and password not working

[tariq-ali]

Hi. I have an instance of containerlab running on debian/orbstack. I'm trying to deploy a vJunos-switch. The default username and password admin:admin@123 does not work. I've tried playing around with a startup config to change the password and I still am unable to login to the switch. Any ideas on what I could possibly being doing wrong? Thank you.

Hi
if the log stops at this point, it means the hypervisor couldn't start the VM. Some HW/virtualization issues

Hi. Thank you. I will look into that. As an FYI, I can get into the bash shell via docker exec -it bash and see the juniper.conf file but can't get to Junos CLI from there or directly via SSH.

I should've included the entire log after the environment variables:

i tried this with different HW/Virtualization and it worked. Thank you!
