https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262113 Bug ID: 262113 Summary: bhyve fails every other attempt to run Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: risner@stdio.com using an UEFI OS and the commands executed below, you may start bhyve. Regardless of the way you exit (ctrl-c, halt or reboot from inside the vm); when you retry you will get an invalid argument error. Retrying immediately after, it works. The cycle then repeats. bhyvectl --destroy --vm=3Dtest0 bhyve -AHP -c 1 -m 1024M -S -s 0,hostbridge -s 1,lpc -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -s 3,ahci-hd,efiboot.i= mg -s 29,fbuf,tcp=3D203.0.113.46:5900,w=3D800,h=3D600 test0 >From testing modifications to bhyve, the libvmmapi, and the kernel module I found that line 1006 of bhyverun.c calls vm_create and returns with EEXIST despite there being no entry in /dev/vmm and having ran bhyvectl --destroy immediately before bhyve. I could not conclusively prove what exactly is going on inside the kernel module. It fails on FreeBSD-13 p4 and p7. It failed on two different Cisco amd64 systems I had. If you don't have a testing OS with uefi, you can make a temporary one with this: dd if=3D/dev/zero of=3Defiboot.img bs=3D300m count=3D1 mdconfig -a -t vnode -f efiboot.img gpart create -s gpt md0 gpart add -t efi -s 256m md0 newfs_msdos -F 32 -c 1 -m 0xf8 /dev/md0p1 # format efi mount -t msdosfs /dev/md0p1 /mnt mkdir -p /mnt/EFI/BOOT wget -O /mnt/EFI/BOOT/BOOTX64.efi https://sourceforge.net/projects/supergrub2/files/2.04s1/super_grub2_disk_2= .04s1/super_grub2_disk_standalone_x86_64_efi_2.04s1.EFI/download umount /mnt mdconfig -d -u 0 --=20 You are receiving this mail because: You are the assignee for the bug.=
