I have successfully installed a OpenBSD 7.3 arm64 VM on UTM 4.2.5 on a Mac mini (2023) with an M2 Pro CPU.
In order to see console output I needed to enter »set tty fb0« at the boot> prompt. Later I was able to create a /etc/boot.conf file with that content. This worked fine for the following reboots. No more manual entry of the setting necessary. When trying to research the syntax and possible content of the /etc/boot.conf file, I came across config(8). It mentions boot.conf(8). But that man page does not exist on the arm64 platform. I found https://man.openbsd.org/OpenBSD-7.3/boot.conf.8 though. https://man.openbsd.org/arm64/boot.conf.8 is also missing so this has not been fixed in -current. Seems like a bug to me. I think there should be a boot.conf(8) man page on arm64 as that file clearly works when present. vm# uname -srmv OpenBSD 7.3 GENERIC.MP#2080 arm64 vm# man 8 config vm# man 8 boot.conf man: No entry for boot.conf in section 8 of the manual. vm# dmesg: OpenBSD 7.3 (GENERIC.MP) #2080: Sat Mar 25 14:20:25 MDT 2023 dera...@arm64.openbsd.org:/usr/src/sys/arch/arm64/compile/GENERIC.MP real mem = 2137935872 (2038MB) avail mem = 2037706752 (1943MB) random: good seed from bootblocks mainbus0 at root: ACPI psci0 at mainbus0: PSCI 1.1 cpu0 at mainbus0 mpidr 0: Unknown, MIDR 0x0 cpu0: 192KB 64b/line 6-way L1 PIPT I-cache, 128KB 64b/line 8-way L1 D-cache cpu0: 16384KB 128b/line 16-way L2 cache cpu0: TLBIOS+IRANGE,TS+AXFLAG,FHM,DP,SHA3,RDM,Atomic,CRC32,SHA2+SHA512,SHA1,AES+PMULL,SPECRES,SB,FRINTTS,GPI,LRCPC+LDAPUR,FCMA,JSCVT,API+PAC,DPB,SpecSEI,PAN+ATS1E1,LO,HPDS,CSV3,CSV2,DIT cpu1 at mainbus0 mpidr 1: Unknown, MIDR 0x0 cpu1: 192KB 64b/line 6-way L1 PIPT I-cache, 128KB 64b/line 8-way L1 D-cache cpu1: 16384KB 128b/line 16-way L2 cache cpu1: TLBIOS+IRANGE,TS+AXFLAG,FHM,DP,SHA3,RDM,Atomic,CRC32,SHA2+SHA512,SHA1,AES+PMULL,SPECRES,SB,FRINTTS,GPI,LRCPC+LDAPUR,FCMA,JSCVT,API+PAC,DPB,SpecSEI,PAN+ATS1E1,LO,HPDS,CSV3,CSV2,DIT efi0 at mainbus0: UEFI 2.7 efi0: EDK II rev 0x10000 smbios0 at efi0: SMBIOS 3.0.0 smbios0: smbios0: QEMU QEMU Virtual Machine apm0 at mainbus0 ampintc0 at mainbus0 nirq 288, ncpu 2 ipi: 0, 1, 2: "interrupt-controller" ampintcmsi0 at ampintc0: nspi 64 agtimer0 at mainbus0: 24000 kHz acpi0 at mainbus0: ACPI 6.0 acpi0: sleep states acpi0: tables DSDT FACP APIC PPTT GTDT MCFG SPCR DBG2 IORT BGRT acpi0: wakeup devices acpimcfg0 at acpi0 acpimcfg0: addr 0x4010000000, bus 0-255 acpiiort0 at acpi0 "ACPI0007" at acpi0 not configured "ACPI0007" at acpi0 not configured pluart0 at acpi0 COM0 addr 0x9000000/0x1000 irq 33 pluart0: console "QEMU0002" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured "LNRO0005" at acpi0 not configured acpipci0 at acpi0 PCI0 pci0 at acpipci0 0:1:0: rom address conflict 0xfffc0000/0x40000 "Red Hat Host" rev 0x00 at pci0 dev 0 function 0 not configured virtio0 at pci0 dev 1 function 0 "Qumranet Virtio Network" rev 0x00 vio0 at virtio0: address 0e:25:ed:1c:38:1d virtio0: msix shared virtio1 at pci0 dev 2 function 0 "Qumranet Virtio 1.x GPU" rev 0x01 virtio1: no matching child driver;
