<br>We have chosen to use libvirt in order to deal, in a generalized way, with the<br>process of starting virtual machines, stopping them, executing remote commands and creating shared folders.<br>As we saw that libvirt cannot handle with executing remote commands without any manual configuration by us (setting up consoles, through ssh, etc.), we will basically use a shared folder to store scripts that are to be executed by the guest, and the guest would have a running daemon that monitors this shared folder and executes everything in it.<br>
<br>Do you know how could I share a folder with a VBox guest through actual Libvirt code?<br>We are also trying to do this through the Java binding, but it won't work either. As you said, it's not supported yet.<br>
We will eventually have to do this for all other hypervisors supported by Libvirt, so I'd like to know: which hypervisors have this shared folder funcionality supported by Libvirt?<br><br>We are very thankful for your answers and willing to see new feature in the next version!<br>

</div>VirtualBox shared folders don't support setting an access mode. The<br>
target dir will map to the name of the shared folder in the guest.<br>
Also the template type is OpenVZ specific. A shared folder will<br>
probably just map to this XML snippet:<br>
<br>
<filesystem type='mount'><br>
<source dir='/home/guilhermesgb/Desktop/SharedFolder'/><br>
<target dir='myshare1'/><br>

You might also specify the <readonly/> option.<br>

</div>As I said libvirt just doesn't support this yet, but I'll look at it.<br>
