oVirt 4 einrichten

Im folgenden Teil wird erklärt wie oVirt  eingerichtet werden kann.

Zunächst muss die Paketquelle hinzugefügt werden:

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm

Danach müssen die benötigten Softwarepakete installiert werden:

# yum install ovirt-engine -y

Im Anschluss kann mit engine-setup das Installationsprogramm gestartet werden.

# engine-setup

          In order to configure firewalld, copy the files from
              /etc/ovirt-engine/firewalld to /etc/firewalld/services
              and execute the following commands:
              firewall-cmd --permanent --add-service ovirt-postgres

Wenn die Firewall aktiviert ist muss man noch die oben aufgelisteten Aktionen durchführen.

Wenn SPICE von extern verwendet werden können soll muss noch folgende Regel hinzugefügt werden:

# firewall-cmd --permanent --add-port 5634-6166/tcp

Danach kann man sich am Webportal über die 2 ausgegebenen Adressen verbinden und einloggen.

Zunächst muss der lokale Host hinzu gefügt werden:
“System -> Data Centers -> Default -> Clusters -> Default -> Hosts -> New”

Die erfolgt über die Angabe von Namen IP und root Passwort.
Der Installationsprozess kann eine weile dauern.

NFS Exports erstellen:

# vi /etc/exports
/mnt/raid6/exports/isos         vmnode1(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
/mnt/raid6/exports/data         vmnode1(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

Nach müssen die shares neu geladen werden und die Berechtigungen für oVirt angepasst werden:

# exportfs -a
# chown -R vdsm:kvm /mnt/raid6/exports
# chown -R vdsm:kvm /mnt/raid6/exports

Im Anschluss kann der NFS Server aktiviert und gestartet werden:

# systemctl start {nfs-server,nfs-lock,nfs-idmap}
# systemctl enable {nfs-server,nfs-lock,nfs-idmap}
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

Da oVirt noch NFS3 als Standard Version verwendet empfiehlt es sich NFS in der /etc/nfsmount.conf wie folgt zu konfigurieren:

[ NFSMount_Global_Options ]
# This statically named section defines global mount
# options that can be applied on all NFS mount.
#
# Protocol Version [2,3,4]
# This defines the default protocol version which will
# be used to start the negotiation with the server.
Defaultvers=3
#
# Setting this option makes it mandatory the server supports the
# given version. The mount will fail if the given version is
# not support by the server.
Nfsvers=3

Nach dem die Speicherplätze verfügbar sind können diese in oVirt eingehangen werden:
„System -> Data Centers -> Default -> Storage -> New Domain“:

Danach sollte es so aussehen:

Nun ist oVirt bereit für die Verwendung
