Actually it seems those were "warnings" only.. xend does start automatically 
now on centos7. 
So it's not a problem really.

Actually I don't see libvirt rpms in the virt7-xen-44-testing repo. Which 
libvirt rpms should I be testing? 

Currently I have these installed:

virt-viewer-0.6.0-12.el7.x86_64
libvirt-daemon-1.2.8-16.el7_1.4.x86_64
virt-manager-common-1.1.0-12.el7.noarch
libvirt-client-1.2.8-16.el7_1.4.x86_64
libvirt-python-1.2.8-7.el7_1.1.x86_64
virt-manager-1.1.0-12.el7.noarch
libvirt-daemon-driver-network-1.2.8-16.el7_1.4.x86_64
libvirt-daemon-config-network-1.2.8-16.el7_1.4.x86_64
libvirt-glib-0.1.7-3.el7.x86_64

I'm currently in the process of testing these latest Xen 4.4.3 rpms on centos7.

That link seems broken.. this one works:

OK. I can now see the libvirt 1.2.15-3.el7 rpms in the virt7-xen-44-testing 
repo,
but it seems yum still doesn't pick them up:

# yum clean all
# yum --enablerepo=virt-xen-44-testing update
..
No packages marked for update

# rpm -qa | grep -i libvirt-daemon-1
libvirt-daemon-1.2.8-16.el7_1.4.x86_64


I guess I'll install those 1.2.15-3.el7 rpms manually.

It seems now the packages installed OK using yum aswell. I guess you or someone 
refreshed the repo :)

Anyway, here's something I noticed while testing xend bits:

# systemctl enable xend.service
xend.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig xend on
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).


"systemctl start xend.service" works OK though.. and after that xm works too.

[CentOS-virt] CentOS 7 Xen 4.4.3 packages available for in virt7-xen-44-testing

[George Dunlap]

Updated Xen 4.4.3 packages have passed my local smoke tests, and are
now available.

Full C7 release is still waiting on suitable testing for the libvirt packages.

If someone wants to step up to give the libvirt packages a decent
smoke test, that will speed the C7 release process significantly.
Otherwise it will have to wait until I get a chance to write some
automated smoke tests.

In the mean time, here's how to install the core Xen packages:

rpm -ivh 
http://cbs.centos.org/repos/virt7-xen-44-testing/x86_64/os/Packages/centos-release-xen-7-3.el7.x86_64.rpm

This will set up yum repositories for both the eventual release
repositories (enabled by default), and the community build system
repositories (disabled by default).

At the moment, all packages will be stored in the virt-xen-44-testing
repository.  You can either enable this by default by editing
/etc/yum.repos.d/VirtSIG-Xen.repo, or by adding
"--enablerepo=virt-xen-44-testing".

If you want, you can edit defaults /etc/sysconfig/xen-kernel

Next, run 'yum update' to get the new kernel:

yum --enablerepo=virt-xen-44-testing update kernel

Now install xen:

yum --enablerepo=virt-xen-44-testing install xen

This should grab both xen and the updated kernel package.  It should
also automatically:
* Add default commandline parameters for Xen and Linux when booting under Xen
* Arrange for xen to come up first in the grub
* Set the default boot entry to Xen.

That's it!  Reboot and you should be good to go.

Please report any problems or feedback to this list.

 -George
