Yet another problem with Genode+Nova_x86_64+VirtualBox on USB stick

[1 2]

Hello, Alexander!

I try to run Win7 32-bit (appropriate win7.vdi is quite small, less than 2G). I've read previsously that current vbox port does not support 64-bit guest systems.

I injected several debug messages into usb_drv and rump_fs. It seems that usb_drv (and underlying layers) works correct (scsi_cmdn.result is always 0), while rump_fs reports that rump_sys_pread always return -1. Also vbox did several writes into win7.vdi, and rump_sys_pwrite always return requested amount of bytes! Moreso, vbox successfully creates /Logs dir, but it's empty. So I suspected either original rump library or part_blk. 

Still investigating this puzzle.
