Public bug reported: Using Utopic (14.10) as Xen host, any attempt to start a HVM guest results in "MMIO emulation failed" and a triple fault.
The problem is that seabios version 1.7.5-1, from Debian drops support for Xen in the 128K image. And this is compiled into Xen hvmloader at build time. Luckily this can be worked around by picking the 256K image, at least for Xen 4.4 onwards. ** Affects: xen (Ubuntu) Importance: Critical Assignee: Stefan Bader (smb) Status: Triaged -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to xen in Ubuntu. https://bugs.launchpad.net/bugs/1370123 Title: [Utopic] Xen HVM guests fail to start (MMIO emulation failed) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xen/+bug/1370123/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
