Hi. I use VyOS 1.1.5 (virtual 64-bit) in Proxmox enviropment. Very often get syslog error:
13.07.2015 10:48:45 vpn-01.dc1.b2b-center.ru Error Security vpn-01 getty getty[20676]: ttyS0: tcgetattr: Input/output error
13.07.2015 10:48:35 vpn-01.dc1.b2b-center.ru Error Security vpn-01 getty getty[20675]: ttyS0: tcgetattr: Input/output error
13.07.2015 10:48:25 vpn-01.dc1.b2b-center.ru Error Security vpn-01 getty getty[20674]: ttyS0: tcgetattr: Input/output error
13.07.2015 10:48:15 vpn-01.dc1.b2b-center.ru Error Security vpn-01 getty getty[20673]: ttyS0: tcgetattr: Input/output error
13.07.2015 10:48:05 vpn-01.dc1.b2b-center.ru Error Security vpn-01 getty getty[20672]: ttyS0: tcgetattr: Input/output error
What is the possible cause of this error? How will i can resolve it?
Looks like spurious serial port errors, probably because one is not available.
VM don’t have serial port. What can i do for solve the problem?
There is no problem per se, you just don’t have a serial port.
If you don’t want the messages logged, probably something in inittab needs to be commented out.

Don’t help me. Have syslog error after delete system console. Also when i commit delete system console, get the message:
[ system console device ttyS0 ]
Warning: Access to system console is unconfigured
I had this same issue on a new install (1.1.7). I added the console, removed it again, and rebooted and the issue went away
set system console device ttyS0
delete system console
commit
save
reboot
