#tcp: [2],1 iqn.2000-01.com.synology:SynNAStestA.oVirtEngine.2776b78dce (non-flash)
#tcp: [3],1 iqn.2000-01.com.synology:SynNAStestA.oVirtData.2776b78dce (non-flash)
#tcp: [4],1 iqn.2000-01.com.synology:SynNAStestA.oVirtData.2776b78dce (non-flash)


For VNC Connections run this

hosted-engine --add-console-password


#To enable libvirt command line calls run the following command. If you ever use libvirt commands you can use the username/password below to access them.

saslpasswd2 -a libvirt myfavoriteusername


If you SSH into the  oVirtEngineVM as root, run the following config commands:

#this sets up VNC as the default console type and will allow console to run in web browser
engine-config -g ClientModeVncDefault
engine-config -s ClientModeVncDefault=NoVnc
engine-config -g ClientModeVncDefault


engine-config -s vdsConnectionTimeout=2
engine-config -s vdsRetries=0


Setup engine backup

vi /root/backup_my_engine.sh

#required for cronjob
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd $DIR

export TERM=xterm

BUDATE=date "+%Y-%m-%d-%H%M%S"

engine-backup --mode=backup --file="engine-backup${BUDATE}.bak" --log="engine-backup${BUDATE}.log"

cp /root/engine-backup${BUDATE}* /mnt/backups/engine/
rm /root/engine-backup${BUDATE}*

vi /etc/crontab
#add the following line at the bottom
38 17 * * * root /root/backup_my_engine.sh > /dev/null 2>&1
vi /etc/fstab
#add this line to the bottom of the file /mnt/backups nfs rw,async,hard,intr,noexec 0 0
mkdir /mnt/backups
mount /mnt/backups
mkdir /mnt/backups/engine

Set UI to never end session

engine-config -s UserSessionTimeOutInterval=-1
service ovirt-engine restart

Setup Notifier

vi /usr/share/ovirt-engine/services/ovirt-engine-notifier/ovirt-engine-notifier.conf
#Add this to the end of the file
systemctl daemon-reload
systemctl enable ovirt-engine-notifier.service
systemctl restart ovirt-engine-notifier.service
