Package: xen-hypervisor-4.17-amd64
Version: 4.17.5
Once XEN is installed on a Debian 12 Virtual Machine with Nested Virtualization
enabled this will create a boot loop.
Here is a transcript:
*
install Debian 12 under VMWare Workstation 17.6.3 (or another Hypervisor)
*
Host OS : Windows 10 (or Linux)
*
Host CPU : Intel i7 10th gen or another Intel CPU with Nested Virtualization
support
*
iso : debian-12.10.0-amd64-DVD-1.iso
*
VM config CPU : Virtualize Intel VT-x/EPT or AMD-V/RVI enabled
*
install XEN on Debian 12 -
*
$ apt install xen-hypervisor
*
$ reboot
*
boot loop on the new added GRUD entries
*
Debian GNU/Linux, with Xen Hypersior => boot loop
*
Advanced options for Bebian GNU/Linux (with Xen Hypervisor) => boot loop

I suggest that this regression fix introduced in XEN 4.17.3 should be included
in the upcoming XEN 4.17.6 or if it is not possible a custom patch by Debian.
