I tested it and it is OK; # uname -a Linux ltc-wspoon3 4.15.0-39-generic #42-Ubuntu SMP Tue Oct 23 15:41:45 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1792957 Title: Provide mode where all vCPUs on a core must be the same VM Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: In Progress Status in linux source package in Bionic: Fix Committed Status in linux source package in Cosmic: Fix Committed Bug description: == SRU Justification == This patch has been requested by IBM. It provides a mode where all vCPUs on a core must be the same VM. This is intended for use in security-conscious settings where users are concerned about possible side-channel attacks between threads which could perhaps enable one VM to attack another VM on the same core, or the host. == Fix == linux-next commit: aa2278644ae5 ("KVM: PPC: Book3S HV: Provide mode where all vCPUs on a core must be the same VM") == Regression Potential == Low. Changes limited to powerpc. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. == Comment: #0 - Leonardo Augusto Guimaraes Garcia <lagar...@br.ibm.com> - 2018-09-13 07:12:48 == +++ This bug was initially created as a clone of Bug #171443 +++ Please, add the following patch: http://patchwork.ozlabs.org/patch/968786/ which adds a mode where all vCPUs on a core must be the same VM on POWER8 and POWER9.
