https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292798 Bug ID: 292798 Summary: bhyve: VMX triple fault in efi windows bootloader Product: Base System Version: 15.0-STABLE Hardware: amd64 OS: Any Status: New Keywords: bhyve Severity: Affects Some People Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: nikolaytihonov2022@gmail.com Hi. I'm having not so great time with Windows Server under Bhyve. In fact it doesn't boot past windows bootmgr.efi or bootmgfw.efi - VMX Triple Fault root@z440:/usr/local/vm/vm-720 # bhyve \ -c 1,sockets=1,cores=1,threads=1 \ -m 4096M -w \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \ -U 56da390d-fc0d-11f0-81a2-5cb901933e24 \ -s 0,hostbridge \ -s 31,lpc \ -s 3:0,nvme,/dev/zvol/zroot/vm/vm-710-disk0 \ vm-720 vm exit[0] reason VMX rip 0x00000000015d1f37 inst_length 2 status 0 exit_reason 2 (Triple fault) qualification 0x0000000000000000 inst_type 0 inst_error What have been tried: 1. Adding/removing virtio devices (NICs, disks) 2. Adding/removing nvme disk 3. Changing guest CPU (sockets/cores/threads) 4. Changing guest RAM size 5. Changing hostbridge to hostbridge_amd 6. Forcing virtio devices to use MSI instead of MSI-X (-W) 7. Igoring MSRs (-w) 8. x2APIC (-x) 9. Disabling MPtable geenration (-Y) As well as I tried different Windows versions. Booting from ISO directly, or booting from old backup - triple fault, but at different places. This server currently runs 6 bhyve VMs thorough vm-bhyve. Also runs VNET jails and performs IPFW firewalling. FreeBSD and Linux UEFI guests run without issues flawlessly under Bhyve.
