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. 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. ** Affects: ubuntu-power-systems Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) Status: New ** Tags: architecture-ppc64le bugnameltc-171450 severity-medium targetmilestone-inin16041 -- Provide mode where all vCPUs on a core must be the same VM https://bugs.launchpad.net/bugs/1792955 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
