Public bug reported: [Impact]
* QEMU does not work in some AMD hardware when using host-passthrough as cpu-mode (usually to allow nested KVM to work). * QEMU does not start, hanging before the VM initialization. [Test Case] * to use Xenial qemu on top of a regular Xenial kernel -> doesn't work (intermittent) * to use the following XML file: https://paste.ubuntu.com/p/BSyFY7ksR5/ * to have AMD FX(tm)-8350 Eight-Core Processor CPU or similar * to use Xenial qemu on top of a HWE kernel -> works [Regression Potential] * TODO [Other Info] * TODO ** Affects: linux (Ubuntu) Importance: Medium Status: Fix Released ** Affects: linux (Ubuntu Bionic) Importance: Medium Assignee: Rafael David Tinoco (rafaeldtinoco) Status: Confirmed ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Bionic) Status: New => Confirmed ** Changed in: linux (Ubuntu Bionic) Importance: Undecided => Medium ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => Rafael David Tinoco (rafaeldtinoco) ** Changed in: linux (Ubuntu) Importance: Medium => Undecided ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Released ** Changed in: linux (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834522 Title: Bionic QEMU with Bionic Kernel hangs in AMD FX-8350 with cpu-host as passthrough To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
