Lightboard Lessons: F5 BIG-IP Virtual Edition Lab Configuration

Is this method still working/supported on BIGIP-15.1.0-0.0.31.LTM_1SLOT?

After changing the password back to default (by doing an intermediate step to another password, as the first login requires a mandatory password change), packer seems to fail to connect with Big-IP over ssh. I can login with the credentials in the VirtualBox UI console though.

If I look into the Virtualbox UI, I see that mcpd and devmgmtd are in a crashloop.

logger[22111] Re-starting mcpd
logger[22818] Re-starting devmgmtd
logger[22332] Re-starting mcpd

The output of dmesg shows the tmm interface flapping.
