The IOS XRv 9000 node fails to boot / gets stuck in a boot loop.
It does get to this point in the boot process, but doesn't progress further, even if you wait (30mins+)
I understand this is a resource intensive node, but its been months since this was a last able to boot successfully.
I believe it is using v7.4.1 and runs with the default allocated resources.
