[ Upstream commit 933b5f9f98da29af646b51b36a0753692908ef64 ]
Instead of printing an error message, kvm_stat script fails when we restrict statistics to a guest by its name and there are multiple guests with such name:
# kvm_stat -g my_vm Traceback (most recent call last): File "/usr/bin/kvm_stat", line 1819, in <module> main() File "/usr/bin/kvm_stat", line 1779, in main options = get_options() File "/usr/bin/kvm_stat", line 1718, in get_options options = argparser.parse_args() File "/usr/lib64/python3.10/argparse.py", line 1825, in parse_args args, argv = self.parse_known_args(args, namespace) File "/usr/lib64/python3.10/argparse.py", line 1858, in parse_known_args namespace, args = self._parse_known_args(args, namespace) File "/usr/lib64/python3.10/argparse.py", line 2067, in _parse_known_args start_index = consume_optional(start_index) File "/usr/lib64/python3.10/argparse.py", line 2007, in consume_optional take_action(action, args, option_string) File "/usr/lib64/python3.10/argparse.py", line 1935, in take_action action(self, namespace, argument_values, option_string) File "/usr/bin/kvm_stat", line 1649, in __call__ ' to specify the desired pid'.format(" ".join(pids))) TypeError: sequence item 0: expected str instance, int found
To avoid this, it's needed to convert pids int values to strings before pass them to join().
