ERROR: sector 0 does not have an msdos signature... and others.
Janusz Syrytczyk
I already have Ganeti 2.4 working but I'm testing 2.5 now, single
machine, plain storage. I currently can't create machines
debootstrap+default, or, more precisely, I create them without being
able to boot from hdd. I can only boot and install from cd.

Any obvious reason? I've tried several versions of debianutils, no
change. Thank you.

You can try passing a ganeti kernel and initrd, as that might make debootstrap skip that part. But the problem lies in how the debootstrap scripts prepare the disk: take a look at them, and perhaps run them in debugging mode, to find out what's wrong or what you need to add. They're just bash scripts, so they should be easy to follow. Perhaps one of the programs they use changed some requirements. Wouldn't be the first time.
