since you are including this path assume you use
-I/path/to/libvirt/source and don't have libvirt installed in your
system. Hence you need to provide linker the path where it will find the
library:
gcc -I/path/to/libvirt -L/path/to/libvirt/src -lvirt ex1.c -o ex1

or just install libvirt ('sudo make install' in /path/to/libvirt) and
then you can drop both -I and -L arguments.
