[ovirt-devel] compile vdsm and attach it to a engine

Thu Jul 3 02:16:15 UTC 2014

Hi,

Thank you for your great job on ovirt and vdsm. Now I devote myself to
compile vdsm on centos 6.3 host and attach it to a ovirt engine. But when I
attach the host which contains a compiled vdsm to a ovirt engine , the
status of the host is always ‘Non Responsive’(step 11 below). I reference
the links below:

http://www.ovirt.org/Vdsm_Developers

http://www.ovirt.org/Installing_VDSM_from_rpm

The steps( 1-9 ) are executed on centos6.3 host, and the steps(10--11) are
executed on ovirt engine. So I would be very grateful if you can give me
some clues that if I've missed anything or I done something wrong.

The attachment is the same as the bellow which makes it easier for you to
read.
1 Deployment platform

 Centos6.3

x86_64 x86_64 x86_64 GNU/Linux

 Ip ： 10.1.8.252

 2 Apply all updates # yum  -y update  3 Installing required packages

RHEL 6 users must add EPEL yum repository for installing python-ordereddict
and pyton-pthreading. The rpm bellow will install the epel yum repo and
required gpg keys.

# yum install http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

RHEL 6 users must install a newer pep8 version than the one shipped in
EPEL6. Older pep8 versions have a bug that's tickled by vdsm. You can use
`pip`, or

yum install http://danken.fedorapeople.org/python-pep8-1.4.5-2.el6.noarch.rpm

oVirt repo:

yum install http://resources.ovirt.org/releases/ovirt-release.noarch.rpm

RHEL 6 users must add the glusterfs repository, providing newer glusterfs
not available on RHEL 6. Optionally install 'wget' if not present

rpm -q wget 2> /dev/null || yum install wget

wget -O /etc/yum.repos.d/glusterfs-epel.repo
*http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo*
<http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo>

Fedora and RHEL 6 users must verify the following packages are installed
before attempting to build:

 yum install make autoconf automake pyflakes logrotate gcc python-pep8
libvirt-python python-devel \

 python-nose rpm-build sanlock-python genisoimage python-ordereddict
python-pthreading libselinux-python\

 python-ethtool m2crypto python-dmidecode python-netaddr
python-inotify python-argparse git \

python-cpopen bridge-utils libguestfs-tools-c pyparted openssl libnl
libtool gettext-devel python-ioprocess  libvirt libvirt-client
libvirt-lock-sanlock

4 Getting the source

cd /root

git clone *http://gerrit.ovirt.org/p/vdsm.git*
<http://gerrit.ovirt.org/p/vdsm.git>

cd vdsm

  5 Building a Vdsm RPM

./autogen.sh –system

./configure --prefix=/usr --sysconfdir=/etc    --localstatedir=/var
--libdir=/usr/lib   --enable-hooks

make rpm NOSE_EXCLUDE=.*
6 Basic installation and start

When building from source, you should enable the ovirt-beta repository, to
satisfy dependencies that are not available yet in the release repository.

# cd ~/rpmbuild/RPMS

# yum install  --skip-broken
--enablerepo=ovirt-master-snapshot-static x86_64/* noarch/vdsm-xml*
noarch/vdsm-cli* noarch/vdsm-python-zombiereaper*
noarch/vdsm-*jsonrpc*

Before starting vdsmd service for the first time vdsm requires some
configuration procedures for external services that being used by vdsmd. To
ease this process vdsm provides a utility (vdsm-tool). To perform full
reconfiguration of external services perform:

# vdsm-tool configure --force

(for more information read "vdsm-tool --help")

7 Finally start the vdsmd service

# service vdsmd start

8  Yum install -y bridge-utils

Configuring the bridge Interface as below

Disable the network manager service by executing as root:

systemctl stop NetworkManager.service

systemctl disable NetworkManager.service

service network start

chkconfig network on

Add the following content into a new file named:
*/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt*:

DEVICE=ovirtmgmt

TYPE=Bridge

ONBOOT=yes

DELAY=0

BOOTPROTO=static

IPADDR=10.1.8.252

NETMASK=255.255.255.0

GATEWAY=10.1.8.254

Add the following line into the configuration file of your out going
interface (usually em1/eth0) the file is located at:
*/etc/sysconfig/network-scripts/ifcfg-em1* (assuming the device is em1)

BRIDGE=ovirtmgmt

and remove the IPADDR, NETMASK and BOOTPROTO keys, since the interface
should not have an IP address of its own. Full Example

DEVICE=em1

ONBOOT=yes

BRIDGE=ovirtmgmt

Restart the network service by executing:

service network restart

*Note that if any other bridge (from ovirtmgmt) is present at the time of
host installation, the bridge creation operation is skipped and you have to
change the bridge settings to correspond to above shown configuration
manually.*

*9 Configuring VDSM*

Add the following content into the file: */etc/vdsm/vdsm.conf* (you may
need to create that file):

[vars]

ssl = false

Restart the vdsmd service by executing:

service vdsmd restart

If Vdsm was started earlier with ssl=true, it would refuse to start and you
may need to use the undocumented verb

service vdsmd reconfigure

service vdsmd start

which edits */etc/libvirt/qemu.conf* and changes *spice_tls=1* to
*spice_tls=0*.

10  Connect to overt-engine

*ref:  OVirt_-_connecting_development_vdsm_to_ovirt_engine
<http://www.ovirt.org/OVirt_-_connecting_development_vdsm_to_ovirt_engine>.*

*su - postgres -c "psql engine -c \"UPDATE vdc_options set option_value =
'true' where option_name = 'InstallVds'\""*

*service  overt-engine restart*
11 Attach the host to the engine

 I login the engine Administration Portal , and attach the centos host to a
cluster. But it failed.
