Title:
KVM module handling different per Architecture - ppc64el
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:
Fix Released
Bug description:
Hi,
the Intel KVM module is build as a modules - the core being KVM and then the
chip vendor specific kvm-intel / kvm-svm.
On ppc64el the situation is similar there is kvm.ko and then kvm-pr and
kvm-hv for problem state and hardware virtualization.
Currently using kvm users can get:
modprobe: FATAL: Module kvm-hv not found ...
But when evaluating if I should add a new recommends to qemu-kvm I
realized this module to kernel package mismatch.
This is caused by one difference, on intel all is in one package:
dpkg -S /lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm-amd.ko
/lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm-intel.ko
/lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm.ko
linux-image-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm-amd.ko
linux-image-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm-intel.ko
linux-image-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/x86/kvm/kvm.ko
But on ppc64el it is not:
$ dpkg -S /lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm.ko
/lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm-hv.ko
/lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm-pr.ko
linux-image-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm.ko
linux-image-extra-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm-hv.ko
linux-image-extra-4.9.0-11-generic:
/lib/modules/4.9.0-11-generic/kernel/arch/powerpc/kvm/kvm-pr.ko
Those should be in just one of these packages.
At a discussion on #stable-kernel it was suggested that it might just have
been missed so far:
<infinity> smb: I doubt it was a conscious move, but rather that
kvm.ko is in the module include list (as inherited from x86 builds),
while the ppc-specific modules are not.
I don't know, but I wanted to open the bug to get it resolved - and if
possible all in the base image.
