[Shivang Upadhyay <shivangu@linux.ibm.com>]

While running remote interrupts test, without libslirp-devel installed,
facing the following panic logs.

  File
    ...
    raise VMLaunchFailure(
    ...<3 lines>...
    ) from exc
    ...
        Output: qemu-system-ppc64: -netdev user,id=net0: network backend
'user' is not compiled into this binary

Skipping the test if vm fails to launch.
