Hi all,
I use the simpletrace.py to analysis a event log and hit the following
assert. Could someone tell me what's the problem?
yyang@host1:~$ ./qemu_2.1.2/scripts/simpletrace.py events trace-*
Traceback (most recent call last):
File "./qemu_2.1.2/scripts/simpletrace.py", line 195, in <module>
run(Formatter())
File "./qemu_2.1.2/scripts/simpletrace.py", line 169, in run
events = _read_events(open(sys.argv[1], 'r'))
File "/home/yyang/qemu_2.1.2/scripts/tracetool/__init__.py", line 263, in
_read_events
event = Event.build(line)
File "/home/yyang/qemu_2.1.2/scripts/tracetool/__init__.py", line 198, in
build
assert m is not None
AssertionError
--- I use the following command to generate the log.
sudo /usr/local/kvm/bin/qemu-system-x86_64 -enable-kvm -drive *file*
=/home/yyang/*vm.img,if*=virtio -cdrom
/mnt/sys/sdb1/ubuntu-14.04.1-server-amd64.iso -boot d -m 4000 -trace
*events*=/home/yyang/events
The events file is as follows:
bdrv_aio_readv
bdrv_aio_writev
Thanks!Ed
