I just build serenity, create grub image and copy it as rootfs for my VM. Grub is loading and system starts to boot. But than it hangs and is killed by qrexec timeout.

For creating VM I used this commands:

$ qvm-create --verbose serenity --class StandaloneVM --property virt_mode=hvm --property kernel="" --property memory=256 --property maxmem=256 --label=red
$ sudo su
$ qvm-run -p my-new-qube 'cat /home/user/serenity/Build/i686/grub_disk_image' > /dev/mapper/qubes_dom0-vm--serenity--root
