Description Igor Mammedov 2013-09-05 10:14:46 EDT
Description of problem:
with upstream kernel commit: ac212b6 (ACPI / processor: Use common hotplug infrastructure)

processor related events have 'DRIVER=processor' bound to them,
as result systemd-204-9.el7.1.x86_64 fails to match auto-load modalias rule:

DRIVER!="?*", ENV{MODALIAS}=="?*", IMPORT{builtin}="kmod load $env{MODALIAS}"

and kvm module is not loaded, which leads to kvm being unavailable on host and virt-install fallbacks to slow TCG accelerator instead of KVM.

systemd upstream fix:
http://cgit.freedesktop.org/systemd/systemd/commit/?id=bf7f800f2b3e93ccd1229d4717166f3a4d3af72f

Please back-port it to RHEL7.0 please as it blocks kernel bug 967561

Version-Release number of selected component (if applicable):
systemd-204-9.el7.1.x86_64
host with 3.10.0-4.el7.kpq kernel

How reproducible:
100% reproducible on
 amd-dinar-08.lab.bos.redhat.com
 and a number of other hosts (see recipe https://beaker.engineering.redhat.com/jobs/464090)

Steps to Reproduce:
1. install  RHEL-7.0-20130722.n.0 Server x86_64
2. install 3.10.0-4.el7.kpq kernel and reboot host
3. lsmod|grep kvm 

Actual results:
 no kvm modules were auto-loaded

Expected results:
 kvm modules are auto-loaded

In RHEL-7, the current systemd version is 206-7, so this patch is already included.
