hi Liam,

not trying to do anything crazy here...  I have used dd for years to copy a
disk.

So this is all on the same machine - sorry for any confusion.
I have my machine.  it supports 3 - PCIE disks.  So I thought I would try
the new PCIe5 so I got one.
turn off my machine - put in PCIE5 disk - rebooted - so now Im back to
running PCIe4 disk and the new PCIe5 disk is just sitting there.

again I do my "dd" command to copy the whole disk. I did forget to mention
the two disks are the same size.

So instead of "rebooting" I thought I would just try to use Virt-manager to
run the new PCIe5 disk. so I created the VM, did the secure boot stuff like
I always do, and attempted to run the new PCIe5 disk - without rebooting
the physical box.

I was surprised that this did not work.  I can try a clonezilla or gparted.

Thanks

Jerry
