Title:
[23.04 FEAT] [VS2029] KVM: Provide virtual CPU topology to guests -
kernel part
Status in Ubuntu on IBM z Systems:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Bug description:
Currently, KVM guests will see an evenly distributed CPU topology,
where every CPU resides on a separate drawer. This may not be optimal
for scheduling decisions. The goal is to allow to specify a virtual
CPU topology which can help to configure the guest for better
performance. The full range of topology nodes should be configurable
(drawer -> book -> chip -> core -> thread).
This has a kernel, qemu and libvirt part.
