   Dear Maintainer,   
   like already mentioned in Bug#1098798, the Linux kernels in Trixie that are   
   installed by linux-image-amd64 are not capable of booting on a Xen hypervisor.   
   This is an issue with the config used to compile the kernel. The error message   
   that's produced is   
      
      
   Loading Linux 6.12.48-amd64 ...   
   error: not xen image.   
   Loading initial ramdisk ...   
   error: you need to load the kernel first.   
      
   Press any key to continue...   
      
   VM type is "pv".   
      
      
   After asking on the Project Xen mailing list I can now say with certainty that   
   the offending config is "CONFIG_KERNEL_ZSTD". Disabling it lets the kernel   
   boot again. The cause is pvgrub not supporting the required zstdio iofilter,   
   which supposedly is    
   being fixed right now with grub-2.14~rc1.   
      
   Best regards
