Serial pass-through on oVirt VMs
Hello, We have an old Windows XP VM, that requires access to a physical serial port for our telephone system. We have this working in VMWare, however, I'm not entirely sure how we would set this up in oVirt? Can someone help please? Kind Regards, Joshua Blake
Hi, you can try to use VDSM hook to add a dummy serial device to the VM domain XML. Or if you really need a physical device then you can use the hook to add the <hostdev> element to the domain XML. Don't forget to pin the VM to a specific host though. Hope this helps, Tomas On Wed, 16 May 2018 10:17:49 +0100 Joshua Blake <maddogmcree2@gmail.com> wrote:

You may want to start from there (warning: NOT tested on real hw or with real VMs) https://gerrit.ovirt.org/91499 bests, -- Francesco Romani Senior SW Eng., Virtualization R&D Red Hat IRC: fromani github: @fromanirh
Take a look at this page [1] for documentation of the hooks system. There is also an example how to use it to change the XML at the end [2].
