This patch adds a new function virFindFileInPath() and uses it to find where a binary lives in the PATH environment variable. Using this, we can dynamically find where utility functions exist (and if they even exists). So such we remove the build-time check for qemu-img and make it dynamic for kvm-img and qemu-img. Several distros uses kvm-img over qemu-img when installing KVM. kvm-img also includes several patches which Red Hat is trying to upstream with QEMU so this patch supports those features which are commented out in libvirt when using kvm-img Signed-off-by: Doug Goldstein <cardoe(a)gentoo.org&gt; --- configure.in | 15 --------- src/libvirt_private.syms | 1 + src/storage_backend_fs.c | 74 ++++++++++++++++++++++++++++++++------------- src/util.c | 28 +++++++++++++++++ src/util.h | 2 + 5 files changed, 83 insertions(+), 37 deletions(-)
