boot/vmmng on real machine doesn't work #46

Open ironista opened 6 years ago

ironista commented 6 years ago

Hi. I'm trying to boot vmmng on a machine with a CPU Intel with VT-x enabled. I have created the bootable iso using novaboot ./b bochs boot/vmmng

Generated iso is successfully booted on qemu 2.0.0, while in my case I got the following error

So I've decoded the backtrace using ./b trace=console and found

Someone of you have experienced with this kind of issue? Thank you.

Error was caused setting x86_32 as NRE_TARGET. Shouldn't it work even on a 64 bit cpu? Anyway, no issue with x86_64.

Nils-TUD commented 6 years ago

It looks like it runs out of memory with x86_32. 256 MiB also seems a bit low for todays machines. Perhaps the remaining RAM is available above 0x100000000? Because this can't be used by x86_32 (it doesn't support PAE).
