Hello,

I tried to setup UserDefinedVMProperties to disable macspoofing for a vm that has to work as hypervisor.

Then I remembered suggestion of Simone about creating vnic profile as an alternate method and set there the filter.

I think I have done something wrong because if I create now a new vm and try to power on it I get

VM test is down with error. Exit message: Hook Error: ('',).

Perhaps I failed the syntax to reset the value of UserDefinedVMProperties ?

I used

[root@ovirt ~]# engine-config -s "UserDefinedVMProperties="

Please select a version:

1. 4.1

2. 3.6

3. 4.0

4. 4.2

[root@ovirt ~]# engine-config -g UserDefinedVMProperties

UserDefinedVMProperties: version: 4.1

UserDefinedVMProperties: version: 3.6

UserDefinedVMProperties: version: 4.0

UserDefinedVMProperties: version: 4.2

[root@ovirt ~]# systemctl restart ovirt-engine

[root@ovirt ~]#

What could be wrong?

Old created VMs start without problem. In the middle I updated the engine from 4.2.5.2 to 4.2.5.3 and also hypervisor packages, where vdsm has remained at level

Aug 03 23:55:09 Updated: vdsm-4.20.35-1.el7.x86_64

In particular:

[root@ovirt01 ~]# rpm -qa|grep vdsm

I found this, but it doesn't seem related:
