Hi there:

Well, now, even without setting up passthrough, the VM doesn't start
(which it did, before I svned up /usr/src).

With vnc:

bhyve  -c 4       -s 0,amd_hostbridge       
-s 3,ahci-hd,/Vmachines/disk.img,sectorsize=512       
-s 4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso       
-s 10,virtio-net,tap0       
-s 11,fbuf,tcp=0.0.0.0:5900,,w=1600,h=900,wait       
-s 20,xhci,tablet       
-s 31,lpc       
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd       
-m 4G -H -w WIN-764
fbuf frame buffer base: 0x942e00000 [sz 16777216]

error:
Assertion failed: (error == 0), function modify_bar_registration,
file /usr/src/usr.sbin/bhyve/pci_emul.c, line 491. Abort trap


Without vnc:

bhyve  -c 4       -s 0,amd_hostbridge       
-s 3,ahci-hd,/Vmachines/disk.img,sectorsize=512       
-s 4,ahci-cd,/Extra/Isos/Windows/Windows_7/null_dvd.iso       
-s 10,virtio-net,tap0       
-s 20,xhci,tablet       
-s 31,lpc       
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd       
-m 4G -H -w WIN-764

error:
Assertion failed: (mr->name == memp->name), function unregister_mem,
file /usr/src/usr.sbin/bhyve/mem.c, line 265. Abort trap


Revisions (/usr/src 11-STABLE):

working:               321652
not working (current): 328163
