Hi cephers,
I want to use the newest features of jewel on my cluster. I already
updated all kernels on the OSD nodes to the following version:
4.8.2-1.el7.elrepo.x86_64.
The KVM hypervisors are running the CentOS 7 stock kernel (
3.10.0-327.22.2.el7.x86_64 )
If I understand it correctly, libvirt/qemu/librbd don't use the kernel
for communication with ceph. At least there is no kernel layer shown in
this diagram: http://docs.ceph.com/docs/master/rbd/libvirt/
The ceph packages are already updated on the hypervisors. On top on all
this there is Openstack, if that's important at all.
My question is: Do I need to update the kernels of the hypervisors if I
only use libvirt as a base?
Regards
David
