# MICROVM kernel configuration, for use with Qemu microvm machine type
# or Firecracker.
# Stripped-down configuration with no PCI, use VirtIO over MMIO virtual
# bus instead. ACPI is disabled as Firecracker doesn't support it,
# use legacy MP tables instead.
#
# Exemple qemu usage on a Linux host to boot a NetBSD guest:
#
# qemu-system-x86_64							\
# 	-M microvm,x-option-roms=off,rtc=on,acpi=off,pic=off,accel=kvm	\
# 	-m 256 -cpu host -kernel ${KERNEL} 				\
# 	-append "root=ld0a console=com rw -z"				\
# 	-display none -device virtio-blk-device,drive=hd0		\
# 	-drive file=${IMG},format=raw,id=hd0				\
# 	-device virtio-net-device,netdev=net0 				\
# 	-netdev user,id=net0,ipv6=off,hostfwd=::2200-:22		\
# 	-global virtio-mmio.force-legacy=false -serial stdio
