I want to use QEMU command line options in a VM's XML configuration.
This requires me to add
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
in the beginning like this.
I'm wondering what this option does, since I am wary of adding it, considering it seems to contain a URL to an internet resource, and it is a HTTP link.
Is this a potential security risk? What does this download, if anything? Could it lead to compromise of the VM or host, if maliciously modified by a man-in-the-middle attack?
