A new kvm guest on a CentOS6.5 x84_64 host is set up to make use of the serial
port (virt-install ... --serial dev,path=/dev/ttyS0)
<serial type='dev'>
<source path='/dev/ttyS0'/>
<target port='0'/>
</serial>
<console type='dev'>
<source path='/dev/ttyS0'/>
<target type='serial' port='0'/>
</console>
When I launch the vm, setroubleshootd goes into overdrive and creates 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
