libvirt users - Feb 2016 - Re: Both virsh console logging and pty usage

Hi,

I am trying to set my VMs for redirecting their consoles to a file but its
important to keep the virsh console access to solve any problem I can find
while they are running. I tried several settings through libvirt (serial
and console tags) but I can not get the key.

Any suggestion? Any help?

Many thanks in advance.

I wrote a piece of code recently that monitors the consoles of the VMs 
and while no one is attached to the console, it throws away the buffer 
as any text appears. If someone *is* attached, it leaves it alone. It 
wouldn't be hard to modify the code to save the console text to a file 
instead of throwing it away. If you are interested, I can post the code.

I'd be quite interested in that code too :), I've started playing with
the
console myself
