      What were you trying to do that didn't work?

      In a Containerfile, use a libguestfs command which ultimately uses libvirt to run qemu. (Running qemu directly works fine). The actual Containerfile is quite complicated, but a simplified reproducer is:

      FROM fedora:42
RUN dnf install /usr/bin/guestfish -y
RUN guestfish -a /dev/null run

      $ podman build -f Containerfile-test
[...]
STEP 3/3: RUN guestfish -a /dev/null run
libvirt: XML-RPC error : Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory
*stdin*:0: libguestfs: error: could not connect to libvirt (URI = qemu:///system): Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory [code=38 int1=2]
Error: building at STEP "RUN guestfish -a /dev/null run": while running runtime: exit status 1

      Modifying the test case to force using qemu:///session fails similarly:

      FROM fedora:42
RUN dnf install /usr/bin/guestfish -y
RUN LIBGUESTFS_BACKEND=libvirt:qemu:///session guestfish -a /dev/null run

      STEP 3/3: RUN LIBGUESTFS_BACKEND=libvirt:qemu:///session guestfish -a /dev/null run
libvirt: XML-RPC error : Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory
*stdin*:0: libguestfs: error: could not connect to libvirt (URI = qemu:///session): Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory [code=38 int1=2]
Error: building at STEP "RUN LIBGUESTFS_BACKEND=libvirt:qemu:///session guestfish -a /dev/null run": while running runtime: exit status 1

      What is the impact of this issue to you?

      We cannot run libguestfs commands in container builds, which we want to do.

      There is a workaround, using LIBGUESTFS_BACKEND=direct, but that is undesirable for other reasons.

      Please provide the package NVR for which the bug is seen:

      It was seen in RHEL 10.0, but this happens in Fedora & likely with upstream libvirt too.
