Hello everyone,

I am new to OpenNebula System. I am having a problem with some settings that can only be done by command line, but cannot be done with the web interface (Sunstone).

Specifically, I cannot declare a variable with the following value:

`ONEAPP_VNF_LB0_IP = “<ETH0_EP0>”`

It’s always showing:

```auto
[one.template.update] Cannot update template. Parse error: XML Template malformed.

```

All variables with values ​​of the form “\< … \>” meet this problem. And it is more annoying because it affects the deployment (when I edit the template by command line, deploying it with Sunstone still fails).

Is there a way to resolve this issue?

Thanks a lot.
