qemu

• Consider the following options:

# `-drive file=disk.img,if=virtio,format=raw` to use `disk.img` as install medium
# `-drive file=glaucus.iso,media=cdrom` vs `-cdrom glaucus.iso`
# `-drive if=pflash,format=raw,readonly=on,file=/usr/share/OVMF/OVMF_CODE.fd`

# `-device qemu-xhci,id=xhci`
# `-device usb-kbd,bus=xhci.0`
# `-device usb-tablet,bus=xhci.0`

# `-device virtio-net,netdev=glaucus -netdev user,id=glaucus`
# `-device virtio-rng-pci`
# `-device virtio-sound-pci,audiodev=glaucusaudio -audiodev alsa,id=glaucusaudio`
# `-device virtio-vga-gl`

# `-netdev user,id=glaucus,hostname=glaucus`
# `-nic model=e1000` if e1000 does not show

• raw is faster than qcow2 but not resizable
• convert qemu raw images to virtual box:

VBoxManage convertfromraw glaucus.img glaucus.vdi

• To resize/grow it use:

VBoxManage modifymedium disk glaucus.vdi --resize $mb

• convert to vdi to run under qemu:

vbox-img convert \
  --srcfilename glaucus.img \
  --dstfilename glaucus.vdi \
  --srcformat RAW \
  --dstformat VDI
