I tested using netboot.xyz on the grml64-small_testing_build1520.iso (with sha1 9d7135a1a8b4fd22948245f3384137abb521fa8f) and experienced the same failure condition; booting the iso directly succeeded (again, both in VirtualBox).

Those are just cosmetic issue and can be ignored.

Ah hm, looking at
https://github.com/antonym/netboot.xyz/commit/1a00e17fd07577aed57a9c560ab513346b5ff808
I'd say that memdisk support in live-boot (which is used in Grml
boot process and responsible for memdisk support) might be broken
then?

Could you maybe test it with a more recent Grml version (our daily
builds) from http://grml.org/daily/ ?
