The security group is configured per VM, the rules are configured by the
system on the node the VM is running on.
From the user perspective you need to configure a security group policy
and then associate the VM with the relevant policy, there is also a
default policy to which all VMs are associated by default.
To use this feature you need to use the oVirt-Neutron integration -

How can I set more than one custom device property?
For example in my case when I had to use extnet I lose the security groups
one...
before
[root@tekkaman ovirt-engine]# engine-config -g CustomDeviceProperties
CustomDeviceProperties: version: 3.0
CustomDeviceProperties: version: 3.1
CustomDeviceProperties: version: 3.2
CustomDeviceProperties: version: 3.3
CustomDeviceProperties: {type=interface;prop={ SecurityGroups=^(?:(?:[0-9a-
fA-F]{8}-(?:[0-9a-fA-F]{4}-){ 3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA- F]{4}-){3}[0-9a-fA-F]{12}|)$}} version: 3.4
then
[root@tekkaman ovirt-engine]# engine-config -s CustomDeviceProperties='{type=
interface;prop={extnet=^[a-zA- Z0-9_ ---]+$}}'
Please select a version:
1. 3.0
2. 3.1
3. 3.2
4. 3.3
5. 3.4
5
after:
[root@tekkaman ovirt-engine]# engine-config -g CustomDeviceProperties
CustomDeviceProperties: version: 3.0
CustomDeviceProperties: version: 3.1
CustomDeviceProperties: version: 3.2
CustomDeviceProperties: version: 3.3
CustomDeviceProperties: {type=interface;prop={extnet=^ [a-zA-Z0-9_ ---]+$}}
version: 3.4
# systemctl restart ovirt-engine
What is the syntax to add extnet without deleting security groups one?
See example on [1], modified a bit to fit you goal:
1. sudo engine-config -g CustomDeviceProperties --cver 3.4
2. Copy the SecurityGroups into variable PREVIOUS_PROPERTIES
i.e.
PREVIOUS_PROPERTIES="SecurityGroups=^(?:(?:[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12},
*)*[0-9a-fA-F]{8}-(?:[0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}|)$"
3. sudo engine-config -s
"CustomDeviceProperties={type=interface;prop={$PREVIOUS_PROPERTIES;extnet=^
[a-zA-Z0-9_ ---]+$}}" --cver=3.4
4. Verify: sudo engine-config -g CustomDeviceProperties --cver 3.4
5. Restart ovirt-engine for changes to reload.
