I'm partially happy about this bug report now: s390x/config.common.s390x:CONFIG_KVM=m
Is still a module rather than built-in on s390x. Unlike x86 there is only one implementation and it should be loaded by default. The trouble is, that it doesn't get autoloaded (and/or when libvirt-bin service tries to load it, it gets permission denied). Please set CONFIG_KVM=y, as without that libvirt does not just work(tm) -- 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/1532886 Title: s390x kernels are inconsistent for cloud stuff Status in linux package in Ubuntu: Fix Committed Status in linux source package in Xenial: Fix Committed Bug description: So to do virtual machine / cloudy stuff things in the kernel config, are not how one would expect them to be.
