USB Serial ports (ttyACMn) CentOS 6.7 (64-bit) vs. CentOS 6.7 (64-bit)
...ux enabled.
I have a USB serial port device (a RR-CirKits LCC-Buffer USB). On the desktop
I am getting this error:
sauron.deepsoft.com% sudo minicom
Device /dev/ttyACM0 access failed: No such file or directory.
sauron.deepsoft.com% dir -lZ /dev/ttyACM0
crw-rw----. root dialout system_u:object_r:tty_device_t:s0 /dev/ttyACM0
But it is working on the laptop!
gollum.deepsoft.com% dir -lZ /dev/ttyACM1
crw-rw----. root dialout system_u:object_r:tty_device_t:s0 /dev/ttyACM1
Same kernel, same device (except it is showing up as ttyACM1 on the laptop).
What is going on here?

libvirt/kvm changes /dev/ttyS0
...ates massive
logs, and /var/log/messages starts growing significantly also. The reason is
that as soon as the vm starts, ownership and context of /dev/ttyS0 on the host
are being reset. Why is that, and how can I prevent it from happening?
Should be:
crw-rw----. root dialout system_u:object_r:tty_device_t:s0 /dev/ttyS0
Changes to:
crw-rw----. qemu qemu unconfined_u:object_r:svirt_image_t:s0:c9,c796 /dev/ttyS0
