Boot stuck as random: unblocking device.

[i.am.the.problem]

I have been trying to network boot a USB image created by nanobsd in a qemu virtual machine but it gets stuck at the following point.

The VM is started with the following command:

qemu-system-x86_64 -smp 4 -m 32G --enable-kvm -rtc clock=host -drive file=freebsd.qcow2 -vga virtio -net nic,macaddr=52:54:12:11:4B:C1 -net bridge,br=br0

The DHCP server is configured as follows:

host vm {
        hardware ethernet 52:54:12:11:4b:c1;
        next-server 192.168.123.4;
        filename "pxeboot";
        option  root-path "nfs://192.168.123.51/mnt";
}

The USB image was copied onto a HDD using the dd command.
Its mounted:

/dev/da2s1a on /mnt (ufs, NFS exported, local, soft-updates)

And exported via nfs:

/mnt -mapall=root:wheel
V4: /   -network 192.168.123.0 -mask 255.255.255.0

Any ideas why it might be stuck at this point?

The installer is looking for a disk labelled by newfs under /dev/ufs and cannot find it. Instead of exporting the installer via NFS, set the USB image as the second drive and boot from it. Add the following to your qemu command line.

-boot order=d -drive path_of_usb_image
