dom0 startup setup failed

[shubham dubey]

I have recently dual booted qubes os with opensuse. Initially everything in qubes was working fine but I just changed the boot loader from qubes to opensuse.After that the vm are stop to start and even the disposable vms are also not starting.

I try to debug the problem and found that on system startup qubes dom0 startup setup, NetVM and sys-net all just failing.The output of qubes core service is

$service status -l qubes-core.service

Got the same problem after installing ubuntu. At first I couldn't manage to boot ubuntu from qubes startup menu, then I run boot-repair from live usb so now I can boot Ubuntu and qubes, but qubes not working properly (Quebes Dom0 startup setup failed)

followed these instructions:

https://www.qubes-os.org/doc/multiboot/

but couldn't boot ubuntu

if you want to reinstall the ubuntu grub, What I do is copy the xen section from the boot.cfg file of qubes boot partition and paste/append that into /etc/grub.d/40_custom file on ubuntu.

Then update-grub and reboot and you should be able to boot qubes from ubuntu grub.

use these instructions for installing the ubuntu grub. https://community.linuxmint.com/tutorial/view/245

Then its the boot.cfg file in grub2 directory of qubes boot partition. From that file copy everything between the xen start and end section. and paste into the 40_custom file on ubuntu. Then update-grub.

You will have to repeat this everytime Qubes updates its kernel.
