description |
[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]

[Impact]
* Nested AMD KVM guest does not work in AMD CPUs when using host-passthrough as cpu-mode.
* QEMU does not start, hanging before the VM initialization.
[Test Case]
* Bionic KVM GUEST tries to use nested KVM in AMD CPU
* 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]
* KVM SVM could be affected but patch is from upstream, fixes the specific issue and has been tested by me in my currently developing workstation (heavy usage).
[Other Info]
* Patches have been sent to kernel team mailing list. |
