oVirt uses VDSM to build the VM/s configuration file (Domain XML).
The only way to control its content from 'outside' is though the hooks:
http://www.ovirt.org/develop/developer-guide/vdsm/hooks/
You could use some usage examples from the code base.

You should only use the management to keep changes.
We added network filtering options in 4.0.
There is also a option of VDSM hook for things that are not supported via
the manager.

Re: [ovirt-users] xml config file being used in ovirt different from virsh?

[Bill Bill]

It seems like when starting the VM through the oVirt dashboard, it’s either 
overwriting or removing those values.

Subject: xml config file being used in ovirt different from virsh?

I have a VM with network filtering enabled, specifically the clean-traffic 
filter.

Through virsh, I modify the configuration to reflect changes like this:

 


  

This only allows those two specified IP’s to communicate on the VM. I’ve 
defined the xml through virsh.

Now, if I start the VM directly through virsh, those rules apply and work 
correctly. I can add any other random IP from the same subnet and it does not 
work, as expected. Only the two Ip’s specified above will respond.

This unfortunately, makes the VM appear to be down from with the ovirt 
dashboard if it’s started manually through virsh.

If I edit the machine through virsh but do not start it and then go onto oVirt 
to start the VM, it seems the configuration is not loaded – does oVirt load a 
different configuration file other than /etc/libvirt/qemu/machine.xml?

[ovirt-users] xml config file being used in ovirt different from virsh?

[Bill Bill]

I have a VM with network filtering enabled, specifically the clean-traffic 
filter.

Through virsh, I modify the configuration to reflect changes like this:

 


  

This only allows those two specified IP’s to communicate on the VM. I’ve 
defined the xml through virsh.

Now, if I start the VM directly through virsh, those rules apply and work 
correctly. I can add any other random IP from the same subnet and it does not 
work, as expected. Only the two Ip’s specified above will respond.

This unfortunately, makes the VM appear to be down from with the ovirt 
dashboard if it’s started manually through virsh.

If I edit the machine through virsh but do not start it and then go onto oVirt 
to start the VM, it seems the configuration is not loaded – does oVirt load a 
different configuration file other than /etc/libvirt/qemu/machine.xml?
