Boot loop when trying to install Xen

[julie-nga]

Hello,

I've tried to install drakvuf . I've downloaded the latest DRAKVUF builds (the .deb files for ubuntu-jammy) and launched them with sudo dpkg -i drakvuf-bundle-1.1-168dac3-ubuntu-jammy.deb and sudo dpkg -i xen-hypervisor-4.19.0-ubuntu-jammy-amd64.deb . This is the output I have for the second command :

[...]

It seems fine but when I do sudo reboot I have a boot loop : the screen switches between these two screens continuously and the VM never starts :

What could I do to solve this ?

(PS: I've also tried doing it on a Debian 11 VM instead of the Ubuntu 22.04 VM but I also had a boot loop so I'm really lost on what to do)

Setup (Nested virtualization)
Host OS: Windows 11
Host VM: Ubuntu 22.04.5 desktop
Virtualization of Host VM: with VMware Workstation

If you attach a serial console to the VM you can probably see the Xen/dom0 boot log to determine what the issue is. My guess would be not enabling nested-VMX feature?

Actually I’ve already enabled the nested-VMX feature on VMware Workstation. For attaching a serial console to the VM, I’m not too familiar with how to set that up, and I’m a bit concerned it might take more time than I can manage right now since I’m new to this.

What confuses me is that I was able to install and run DRAKVUF Sandbox without encountering a boot loop for Xen (on a Debian 11 host VM). I’m not sure why it’s behaving differently in this setup. Any thoughts on what else could be causing this?

Looks to me you are missing the dependencies. Did you run apt-get -f install after you installed the prebuilt deb file with dpkg?
