Hi,

i want to discuss about the support of guest serial console. To access a serial console, i need to add the xml of the device (http://wiki.libvirt.org/page/Unable_to_connect_to_console_of_a_running_domai...):

<serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console>

And, the operation system of the VM need to point to the serial:

console=ttyS0,115200

So, how we can make sure that the user can access the machine by serial console:

1) Just add the xml and let the user add the statement above?

2) Use libvirt to add this parameters (https://libvirt.org/formatdomain.html#elementsOSKernel)

Always try to go the libvirt route if applicable. If libvirt automagically avoids the "console=ttyS0,115200 " statement, better. Daniel
