[BitVisor-devel-en:27] Re: Debugging methods for BitVisor

[平野 学]

Hi Hideki,

I am sorry for your precious time. I have simply forgotten editing boot/login-simple/bitvisor.conf before compiling them.

Thanks to your help, now I can use debgsh both on i3 laptop and on VMware Workstation 9 with its VT-virtualization option. Although I was trying to use QEMU (non-KVM) to run BitVisor, it is very slow. Now I am using physical machines and VMware Workstation 9 on WIndows for my development.

Best regards,
Manabu
