Test script which you can use to see if the bug has been fixed
in the currently installed version of libguestfs (note you will
need to install the Perl bindings -- perl-Sys-Guestfs).
I *always* regret pushing patches without letting them live in several releases of libguestfs ... This patch causes a regression. The child process should display the qemu command line arguments, but it does not when this patch is used. Try running: LIBGUESTFS_BACKEND=direct libguestfs-test-tool With this commit you don't see the full qemu command line. I have reverted this patch in master and will look at fixing it later. Revert commit is 286f116691c8aad4ac8bf0d044e9f6ca8d5b3356. v2 patch is upstream in libguestfs >= 1.27.25 and >= 1.26.7. |
