Thanks, in Ubuntu/Launchpad we keep bugs together in one - hence I'll
mark it a duplicate of the other bug and add a grub2 task there.

Title:
  Jammy grub2 failed to detect 2nd virtio disk

Status in grub2 package in Ubuntu:
  New

Bug description:
  I am using qemu-system-x86_64 on Jammy to create a VM with two disks, both on the virtio bus. 
  When I enter the GRUB shell and use the "ls" command, only the first virtio disk is listed. 
  However, if I change the second disk to the SATA bus, GRUB can recognize the second disk.

  Steps and result

  Jammy: https://paste.ubuntu.com/p/TXjzbcXG5z/

    
  This issue cannot be reproduced on Focal.

  Focal: https://paste.ubuntu.com/p/MF2NKfsTSt/

  
  The impact of this is that chainloading will fail. 

  /etc/grub.d/25_custom
   
  menuentry "Attached-IDE-Disk" {
  set root=(hd1)
  insmod linux
  insmod chain
  chainloader +1
  }

  I'm not sure whether this is an issue with QEMU or GRUB.
