You normally want to run the locally compiled copy of virsh. Trying to run the installed version with the locally compiled library is a recipe for problems with missing symbols and so on. By adding tools to the path we can ensure that (eg) the libguestfs test suite will use compatible copies of the library and virsh. Signed-off-by: Richard W.M.

# With this script you can run libvirt programs without needing to
|
|
# install them first. You just have to do for example:
|
|
#
|
|
# ./run virsh [args ...]
|
|
#
|
|
# Note that this runs the locally compiled copy of virsh which
|
|
# is usually want you want.
|
|
#
|
|
# You can also run the C programs under valgrind like this:
|
|
#
|
|
# ./run valgrind [valgrind opts...] ./program
|
|
#
|
|
# or under gdb:
|
|
#
|
|
# ./run gdb --args ./program
|
|
#
|
|
# This also works with sudo (eg. if you need root access for libvirt):
|
|
#
|
|
# sudo ./run virsh list --all
