vJunos

vJunos on containerlab is routine on Intel. On an AMD EPYC host the stock image refuses to start its nested VM, and the first test topology most people write hides a second failure that looks like AMD and is not. What breaks, what current vrnetlab already fixes, all reproduced on an EPYC 9575F.

Put the vJunos 26.2 images on an AMD EPYC box running EVE-NG: the switch and router power themselves off, patch that and they hang at mount root, and Evolved on the default AMD template never starts QEMU. Four small edits in two places, each reproduced on the EPYC, every command ready to copy.
