[BaaG] BSD As A Guest - DragonFly not booting with ACRN Hypervisor #5844

Open ionutnechita opened 3 years ago

Hi ACRN Team,

I try to start DragonFly with ACRN-DM. But when the kernel was initialized in BSD, it cracked with CPU panic in UOS / BaaG.

In SOS appear this messages: [ 236.721085] vcpu 0[1637]: segfault at 38 ip 0000557c6d159917 sp 00007fd123ffebf0 error 4 in acrn-dm[557c6d13b000+52000] [ 236.721091] Code: f8 02 0f 85 b1 00 00 00 4c 89 eb 48 c1 e3 04 4c 29 eb 48 c1 e3 03 4c 8d 7c 1d 60 4c 89 ff e8 c0 23 fe ff 4c 8b 74 1d 28 31 db <41> 8b 4e 38 85 c9 7e 28 90 49 8b 4e 08 48 63 c3 48 8b 04 c1 48 85

These BSD initialization messages appear on my display: Fatal trap 9: general protection fault while in kernel mode

Hi @ionutnechita , am I understanding you correctly that you are trying to load the DragonFly BSD installer from a CD image and also giving ACRN an empty virtual disk, that I suppose you intent to use as the target installation disk?

What HW are you running on?

Have you tried to create a virtual disk with DragonFly properly installed on it using KVM/QEMU and then use that disk directly with ACRN (similar to what's described here: https://projectacrn.github.io/latest/tutorials/running_deb_as_user_vm.html)?

Hi @gvancuts,

// What HW are you running on?

I use this: Kaby Lake NUC7i7BNH/NUC7i7BNB
