Those are not all missing at least. I have seen ssbd and md-clear for sure in Bionic e.g. for the latter coming with ubuntu/bionic-4.0:debian/patches/md-clear.patch In the context of this bug we will take a look at arch_capabilities and if some of the others are low hanging fruits. Quite often - but not always - for libvirt it is just a CPU bit definition, but as we know e.g. arch_cap is more complex. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828495 Title: [KVM][CLX] CPUID_7_0_EDX_ARCH_CAPABILITIES is not enabled in VM.
