Thank you for your report. From the comments it has yet to be clarified whether there is a bug here, or missing support in libvirt/qemu for your particular requirements which might be considered a Wishlist feature request.
Either way this seems like "unusual end-user configurations or uncommon hardware" so I'm setting Importance to Low. Accordingly I wouldn't expect the Ubuntu Server Team to find the time to look into this soon, but feel free to use this bug to coordinate with others also affected. ** Changed in: libvirt (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936831 Title: libvirt ACPI on unsupported machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1936831/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
