This change updates the nova-next nodeset to use openstack-two-node-noble and revert to using qemu without nested virt. using nested virt was a tempory messure to mitigate the kernel panics we were seeing related to volume detach while we also explored using split kernel images. since then we have reverted the other jobs back to using normal whole disk images and we have not seen a marked uptic in kernel panics. as such this change drop the use of nested virt since the other jobs are not using it an updates the nodeset to move nova-next to test on ubuneu 24.04 (noble) on python 3.12 Depends-On: https://review.opendev.org/c/openstack/devstack/+/922427 Change-Id: I5059ba3c519efb18947a8f3d24868ce1c9289e3d
