[ovirt-users] About Windows guest agent

Hi, I am new in oVirt and I'd like to get the clarification about the packages which support the function of Window guest agent from 4.2 release and how to build it. I looked through the document from ovirt.org, such as https://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-... It mentioned: "With the release of oVirt 3.5 we have introduced the oVirt WGT (Windows Guest Tools). The oVirt WGT provides an ISO with all the tools and drivers one needs to install on a Windows VM, with an easy to use installer to install it all in one step. So manual compilation and installation of oVirt Guest Agent is no longer necessary. The oVirt WGT ISO is included in ovirt-guest-tools-iso-3.5-7.noarch.rpm package." Now, ovirt-guest-tools-iso is up to 4.2.4. I found the src rpm from https://resources.ovirt.org/pub/ovirt-4.2/rpm/el7/SRPMS/ovirt-guest-tools..., but I could not find ovirt-guest-tools-iso from github, only found ovirt-wgt. After clone the ovirt-wgt, I got the SPICE-tools-0.141.iso built. My question is : 1. Is ovirt-wgt used for Windows guest? 2. If so, how can I build ovirt-guest-tools-iso package or ovirt-tools-setup.iso Thanks, Jingjie
