I have been coming closer to what I want (at least for the installation process) using this now sudo virt-install --name=my_domain --ram=512 --vcpus=1 \ --location=/path/to/ubuntu-16.04.1-server-amd64.iso \ --disk /path/to/vm.qcow2,device=disk,bus=virtio,size=32 \ --network bridge:br0 \ --os-type=linux \ --nographics \ --extra-args='console=tty0 console=ttyS0,115200n8 serial' I get a console view of the VM in the hosts console and can attend and guide the installation process as hoped for. I guess --extra-args='console=tty0 console=ttyS0,115200n8 serial' is what enables this. This seems not to be persisting though. After the post-installation's reboot I am at the beginning again Connected to domain ubn1604 Escape character is ^] and the '--extra-args' are not supported by 'virsh console' so, is there any way to get the 'console=tty0 console=ttyS0,115200n8 serial' up again after a reboot? --devname sounds promising but: virsh console --devname 'console=tty0 console=ttyS0,115200n8 serial' [my_domain] only gets me internal error: cannot find character device console=tty0 console=ttyS0,115200n8 serial (same with variations of the above)

wanted to follow up on that part (thanks about all comment suggestion regarding virt-viewer and vcn, etc. I will test them as well but would prefer the 'console way' if possible

* When you are connected you don't see anything because the VM doesn't have console properly set up, I'd guess.
the xml file of my machines (all of them actually) have the below in the 'console' section.

Is it this has to be adjusted in order to 'properly set up the console' ? any pointers what to put here? tried 'bash' for 'type' but that didn't work

This is fine, there is no need to do anything here. As I said, the only thing you need to do is convince the guest kernel to use that ttyS0 as a console (by appending console=ttyS0 as a kernel cmdline parameter). Details on how to do that are explained in my previous mail.
Also, there is no need to guess parts of the configuration, we have a documentation for the XML [1], as well as bunch of other things [2] and working man pages.
