1.4       ryoon      17: You can install latest qemu with the following commands.
                     18: It is assumed that your pkgsrc tree is in /usr/pkgsrc directory.

                     24: 
                     25: The disk image (armv7.img.gz or arm64.img.gz) must first be uncompressed. The *qemu-img* tool can then resize the image to the desired size. On first boot, NetBSD will grow the root file-system to match the size of the disk.

                     46: To bridge a QEMU guest to your network, you need to create a tap(4) interface for your VM, then connect it to a physical interface with a bridge(4) interface.
