[Bug 987710] New: section "Guest CPU models" needs updating
by Red Hat Bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=987710
Bug ID: 987710
Summary: section "Guest CPU models" needs updating
Product: Fedora Documentation
Version: devel
Component: virtualization-deployment-and-administrative-guide
Assignee: lnovich(a)redhat.com
Reporter: me(a)petetravis.com
QA Contact: docs-qa(a)lists.fedoraproject.org
CC: lnovich(a)redhat.com
The section "Guest CPU models" should be updated, comments below:
Background:
- http://wiki.qemu.org/Features/CPUModels has the QEMU roadmap for relevant
features
- rawhide/F20 is currently shipping qemu-1.5.1
- F19 is currently shipping qemu-1.4.2
- F18 is currently shipping qemu-1.2.2
- Fedora ships qemu-kvm as /usr/bin/qemu-kvm not /usr/libexec/qemu-kvm
The first part of the section states CPU configurations are defined in XML
files rather than hardcoded; per the roadmap, they are again hardcoded to allow
compatibility code and more unified processor definitions. There's no
indication of backwards compatibility from qemu, although virsh and friends may
still accept .conf definitions and Know What To Do when talking to qemu.
In F18 and F19, `qemu-kvm -cpu ?cpuid` and `qemu-kvm -cpu ?dump` do not
function.
In F18, `qemu-kvm -cpu ?` gives a terse list of definitions.
in F19, `qemu-kvm -cpu ?` gives a more descriptive list, and also includes a
comprehensive list of recognized CPU flags. This could possibly replace
`?cpuid`
In both, `qemu-kvm -cpu <name>,enforce` functions as expected; this content is
commented out.
Looking further into comparing guest CPU features, I find `virsh capabilities`
will generate xml representing the host. It also appears to represent other
architectures that the host could emulate - if the appropriate packages (ie
qemu-arm ) are installed, and I correctly understand what they do.
There's also `virsh cpu-baseline` to generate a cpu definition that would allow
migration between file-defined hosts, and `virsh cpu-compare` to compare a
defined host with the local host. Both of these rely on [deprecated] xml .conf
cpu definition files. I haven't been able to find a more elegant way to compare
cpu configurations than scripting together the above virsh commands, presuming
`virsh capabilities` works the way I suspect.
The qemu roadmap cites `-cpu best` as a way to get the best CPU definition when
creating a guest - but it doesn't work here, and I'm not sure how it would make
a determination if it did.
A lot of the information I've discovered deals directly with qemu, not libvirt.
With qemu moving back to hard coded cpu definitions, I think it would be good
to get some insight on if libvirt tools are affected and how they are handling
the change. In general, I think it would be better to present libvirt commands
rather than commands executing qemu directly.
I'm not submitting a patch for this one because I'm not sure where to go with
it. It *seems* like libvirt should have a simple way to compare the
capabilities of heterogeneous hosts and aid in creating the best definitions
for guests.

Patch commenting out unavailable guides.
The introduction to the Virtualization Deployment and Administration Guide
references related documentation that has been developed for RHEL/RHEV but is
not maintained for Fedora. The attached patch comments out those sections so
that only guides that are currently maintained for Fedora will be referenced.

The problem description in .pdf format - easy to follow
Hi,
First I want to notice I am a Linux newbie and my English is not that good.
Now straight to the point! (The same description is available in the attached
pdf file and is more easy to follow)
I've noticed some inaccuracy in Fedora 17 “Power Management Guide” (Fedora
Documentation), particularly in section “2.5. Tuned and ktune” including
“2.5.1. The tuned.conf file” and “2.5.2 Tuned-adm”.
In section “2.5. Tuned and ktune” right bellow the “yum install tuned”
command it's written:
“Installing the tuned package also sets up a sample configuration file at
/etc/tuned.conf and activates the default profile.”
There is no such file in /etc. I found a /etc/tuned/active_profile file
containing the following: “/usr/lib/tuned/balanced/tuned.conf”. I'm not sure
this file (/etc/tuned.conf) is missing only on my system or it has a new
location by default for each profile - /usr/lib/tuned/profileX/tuned.conf.
Bellow in this section and in “2.5.1. The tuned.conf file” it is pointed again
that the default location for the tuned.conf file is /etc/tuned.conf.
In section “2.5.2 Tuned-adm” in the first paragraph it is written “Fedora 17
includes a number of predefined profiles for typical use cases...”. Just to be
precise it is good to be mentioned that these profiles are not installed by
default with “yum install tuned” command (tuned-2.0.1-1.fc17 package), but can
be found in tuned-profile-compat-2.0.1-1.fc17 package (I found it in Gnome
Package Manager).
Another thing in this section is in the last third of the page where it is
written:
“All the profiles are stored in separate subdirectories under
/etc/tune-profiles. So /etc/tune-profiles/desktop-powersave contains all the
necessary files and settings for that profile. Each of these directories
contains up to four files:”
There /etc/tune-profiles directory does not exist. Instead I found the profiles
stored in /run/lib/tuned.
Each directory for the corresponding profile typically contains only 2 files -
script.sh and tuned.conf. The presence of script.sh is not mentioned in the
directories contains description – it is mentioned ktune.sh insetad.
That's all. I hope this is helpful.
Best regards
Vasil Draganov
Fedora 17 3.4.0-1.fc17.x86_64
P.S. “Power Management Guide” is great. It's really useful. The moment i run
tuned service i noticed how quieter my laptop became (less heat – less fan
needed :) ). The first thing I noticed about new Fedora installation was that
the laptop was noisier in comparison to Win7 (I dual-boot with Win7). Tuned
just fixed that :)
Many thanks to the creators of Fedora Documentation!!!
