Hi, It also took 6+ hours to boot Linux using that disk image on my end, so I think it's systemd being very slow.
By profiling systemd, I find that systemd took a lot of time to bring up the networking service, and especially the "motd" (message of the day?) service, which queries for updates from Ubuntu servers. We can turn off the motd service, which would improve the booting time by a lot. However, I don't really know how to turn off the network service. I hope that somebody will help with the systemd stuff.
