Description of problem:
Configure the netconsole service in TUI, but it doesn't work.

After configuring the netconsole server ip and port as 6666 and execute the "nc -l -u 6666" on the configured receiver, do something to cause kernel printk message, such as "echo hello > /dev/kmsg",  insert some kernel module and so on. But the receiver can't get any kernel message from the rhev-h host. I check the /proc/sys/kernel/printk, the value is 1, change it to 7, then the receiver can get the kernel message of the rhev-h host.


Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.3-20120531.0.el6


How reproducible:
100%

Steps to Reproduce:
1. install rhev-h and boot up
2. configure the netconsole server and port, apply it
3. use "nc -l -u 6666(the port you set)" to monitor the console message forwarded by rhev-h
4. "echo hello > /dev/kmsg" or insert some kernel module in rhev-h, see the output of "nc -l -u 6666" on the receiver
  
Actual results:
The receiver can't get any kernel message forwarded from rhev-h host. While the /proc/sys/kernel/printk value is 1 by default, change it to 7, the receiver can get the kernel message of rhev-h host


Expected results:
After configuring the netconsole service in TUI, the receiver can get the kernel message of rhev-h host directly, no need to change the printk value
