Hi, booting Windows 10 DVD ISO in a bhyve VM generates an abort trap: ============================================================================== Failed to emulate instruction [0x4c 0x8b 0x3c 0xc8 0x41 0x39 0x7f 0x08 0x76 0x5f 0x49 0x8b 0x0f 0x44 0x8b] at 0x10009bc1 Abort trap (core dumped) ============================================================================== Host-CPU: Core i5 6200U (Skylake) OS: FreeBSD 11.0-BETA3 #12 r303475M Windows probably tries to access some fancy Skylake features. Is there a way to fake my simulated CPU so that it gets detected as an Ivybridge? My current command: ============================================================================== bhyve \ -c 2 \ -s 3,ahci-cd,/root/windows10x64.iso -s 4,ahci-hd,/dev/zvol/zroot/windows10 \ -s 5,virtio-net,tap0 \ -s 11,fbuf,tcp=192.168.10.251:5900,w=1024,h=768 \ -s 20,xhci,tablet \ -s 31,lpc \ -l bootrom,/mnt/vmm/iso/BHYVE_UEFI_20160526.fd \ -m 2G -H -w \ windows10 ============================================================================== Thanks in advance and regards, Nils
