Public bug reported: I have an Ubuntu 20.04 Server running Xen as a Dom0. It's worked fun, but I recently rebooted and the error below appeared
(XEN) ELF: not an ELF binary (XEN) (XEN) **************************************** (XEN) Panic on CPU 0: (XEN) Could not set up DOM0 guest OS (XEN) **************************************** (XEN) (XEN) Reboot in 5 seconds... The LTS release is the same as before, no distribution upgrade. Just a new kernel was installed causing the failure. I tried the extract- vmlinux but I think I might be missing some decompression software as it did not work. In the end I uninstalled the newer kernels, leaving my last good kernel. This forced Xen to boot into that (vmlinuz-5.11.0-43-generic) which works perfectly. It's not great having to run an old version and being forced to run extract-vmlinux (If it worked, which it does not) each time I upgrade the kernel is pretty bad. Since it impacts the Dom0 it's pretty significant.
