It's very strange that you are trying to start DragonFlyBSD using the bootloader from FreeBSD. Yes, vmrun.sh, uses bhyveload(8) by default: >FreeBSD/amd64 User boot lua, Revision 1.2 >Consoles: userboot You should use -E option to choose UEFI bootloader. I was able to successfully run it using the UEFI loader. But only if memory= >=3D 4GB: bhyve -H -A -P -c 1 -m 4G -s 0,hostbridge -s 1,virtio-blk,./dfly.img -s 2,ahci-cd,./dfly-x86_64-5.8.3_REL.iso -s 31,lpc -l com1,stdio -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd dfly If you give the memory less than 4 gigabytes, then a similar error was occu= rs: Unhandled memory access to 0x100000000 Failed to emulate instruction sequence [ 813c8f5f4d505f742483c20439d37f ] at 0xffffffff80bebe43 --=20 You are receiving this mail because: You are the assignee for the bug.=
