This a kind of test that needs some interventions in the kernels of host and guest, and maybe in the Qemu either to analysis the memory area if affected. I believe just a sanity test with page size changing between host and guest will be enough to validate it. I have re-built a kernel package with the patch from source and changing the PAGESIZE support to 4k, then the environment was running with 4k and the guest with 64k without problems. -- 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/1785675 Title: Security fix: check if IOMMU page is contained in the pinned physical page Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Bug description: == Comment: #0 - Leonardo Augusto Guimaraes Garcia - 2018-08-06 12:27:59 == Please, add the following security fix to the distro kernel: 76fa4975f3ed KVM: PPC: Check if IOMMU page is contained in the pinned physical page Also already available in the 4.14 stable tree: 58113603a4ea KVM: PPC: Check if IOMMU page is contained in the pinned physical page And in the 4.17 stable tree: 970e28cb2c7a KVM: PPC: Check if IOMMU page is contained in the pinned physical page To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1785675/+subscriptions -- 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
