# 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
|
