Hi Rich
Have you tried the reproducer from the bug report ?
Using a Debian Testing system with qemu-img 2.10.1 and libguestfs
1.36.11-1 packages I can reproduce it 100 %.
Yes I have now, and yes it does reproduce it reliably.
I'm pretty sure this must be a qemu bug, but it may also be possible
for us to rewrite the code in lib/info.c so that it doesn't do the
strange /dev/fd stuff:
https://github.com/libguestfs/libguestfs/blob/2c359583b3c556c2f52fa2f27bc...
We did this for rather obscure reasons, see:
https://github.com/libguestfs/libguestfs/commit/d50cb7bbb4cc18f69ea1425e9...
and I think it's better to undo this commit.
Rich.
