This might be due to an aborted build still occupying the loop device,
that is used to create sda.img. Have you tried to restart the initvm ?
This should fix that problem.

more information can be obtained, by logging into the initvm using 

"elbe initvm attach" ...

then "losetup -l" ... also look with "mount" whether the loopmounts
are mounted.

to remove them, first "umount" them and then losetup -d can be used.

The x86_64-pc-hdimg-grub-uefi-stretch.xml example is part of our test
suite, and i can say for sure, that it passed in elbe v10 released on
Friday.


if the problem persists please provide the logfile and the output of
"losetup -l" and "mount" after the broken run.
