Greetings,

I have a vm to which I can access using virsh console vm1/ I'd like in addition to be able to dump the serial of the vm in to a file on the host. I've found this https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/htm... but it seems that the first second example which might be suited to what I need doesn't work as I get an empty file: here are my serial config for the vm:

<serial type='pty'> <source path='/dev/pts/2'/> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> <alias name='serial0'/> </serial> <serial type='file'> <source path='/var/log/router-serial.log'/> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> <alias name='serial1'/> </serial> <console type='pty' tty='/dev/pts/2'> <source path='/dev/pts/2'/> <target type='serial' port='0'/> <alias name='serial0'/> </console>

what might be wrong in the above?

I believe what you're looking for is <serial type='pty'> <log file='/var/log/router-serial.log' append='on'/> </serial> <console type='pty'/> See https://libvirt.org/formatdomain.html#consoles-serial-parallel-channel-devic... for more information about configuring serial devices. -- Andrea Bolognani / Red Hat / Virtualization
