When running vmd with an Apline Linux install image, it randomly freezes soon after logging in. This is with the current branch as of today.
Steps to reproduce (the install image is http://dl-cdn.alpinelinux.org/alpine/v3.7/releases/x86_64/alpine-virt-3.7.0-x86_64.iso): $ doas vmctl start test -cd alpine-virt-3.7.0-x86_64.iso vmctl: starting without network interfaces Connected to /dev/ttypa (speed 115200) Changing serial settings was 0/0 now 3/0 SeaBIOS (version 1.10.2p5-OpenBSD-vmm) BUILD: gcc: (GCC) 4.2.1 20070719 binutils: 2.17 enabling shadow ram Unable to unlock ram - bridge not found RamSize: 0x20000000 [cmos] malloc preinit malloc init RamSizeOver4G: 0x0000000000000000 [cmos] init ivt init bda init bios32 init keyboard init pic math cp init pci setup === PCI bus & bridge init === PCI: pci_bios_init_bus_rec bus = 0x0 === PCI device probing === PCI probe Found 4 PCI devices (max PCI bus is 00) === PCI new allocation pass #1 === PCI: check devices === PCI new allocation pass #2 === PCI: IO: c000 - efff PCI: 32: 0000000020000000 - 00000000fec00000 PCI: map device bdf=00:01.0 bar 0, addr 0000c000, size 00001000 [io] PCI: map device bdf=00:02.0 bar 0, addr 0000d000, size 00001000 [io] PCI: map device bdf=00:03.0 bar 0, addr 0000e000, size 00001000 [io] PCI: init bdf=00:00.0 id=0b5d:0666 PCI: init bdf=00:01.0 id=1af4:1005 PCI: init bdf=00:02.0 id=1af4:1001 PCI: init bdf=00:03.0 id=0b5d:0777 PCI: No VGA devices found No apic - only the main cpu is present. init timer Scan for VGA option rom init virtio-blk found virtio-blk at 00:02.0 pci dev 00:02.0 using legacy (0.9.5) virtio mode virtio-blk 00:02.0 blksize=512 sectors=75776 Registering bootable: Virtio disk PCI:00:02.0 (type:2 prio:9999 data:f0a60) init virtio-scsi init serial Found 1 serial ports Scan for option roms Registering bootable: Legacy option rom (type:129 prio:9999 data:bf000003) Searching bootorder for: HALT Mapping hd drive 0x000f0a60 to 0 drive 0x000f0a60: PCHS=0/0/0 translation=lba LCHS=75/16/63 s=75776 Running option rom at bf00:0003 Google, Inc.
