------- Comment From lagar...@br.ibm.com 2015-02-11 15:23 EDT------- On x86, KVM modules are loaded by checking if some processor features are available.
For instance, in my x86_64 laptop: --------------------------- [root@lagarcia ~]# modinfo kvm-intel filename: /lib/modules/3.18.5-201.fc21.x86_64/kernel/arch/x86/kvm/kvm-intel.ko.xz license: GPL author: Qumranet alias: cpu:type:x86,ven*fam*mod*:feature:*0085* depends: kvm <...> --------------------------- The "alias: cpu:type:x86,ven*fam*mod*:feature:*0085*" will instruct the kernel to load this module whenever this feature is available. The same is not true on other platforms. On Power, you need to explicitly load the modules. This is usually done by adding scripts wherever appropriate in the system to automatically load modules during system start up. In the case of KVM modules, these scripts are usually included in the QEMU package. From what I could grasp (sorry if I am mistaken as this is the first time I am looking at an Ubuntu source package), this is already done in Ubuntu through the script qemu-system-ppc.qemu-kvm.upstart. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-utopic in Ubuntu. https://bugs.launchpad.net/bugs/1419855 Title: must manually load kvm_hv or kvm_pr before using kvm on ppc64 Status in linux-lts-utopic package in Ubuntu: New Bug description: on x86_64, kvm modules load automatically. on ppc64, they do not.
