Re: [libvirt] Adding VirtualBox support to libvirt

Hi, As mentioned in the earlier mail, I have started the work on adding Virtualbox support to libvirt. I have completed almost all the basic functionality. Currently I can start, shutdown, reboot, list and suspend/resume the domains. Now I am in the process writing code for creating/defining the domains and thats where i need some help. I am not familiar with the exact XML format required. I have gone through the docs at http://libvirt.org/formatdomain.html as well as the code and have few question regarding the same as below: Is the XML format for defining the Domains common to all the hypervisors? If not then how should I start about defining it for Virtualbox? What exactly does the tag <os_type>xen</os_type> exactly mean? how can xen, hvm, etc be an os type? why virDomainCreate doesn't actually create the domain but it just starts it? (virDomainCreateXML actually creates it) The rest of my question are more general and not related to XML def. In src/qemu_driver.c:qemudGetVersion() why does the qemu driver have to take the lock, i mean what can change while extracting the version info? is there any specific reason? (this is true for other drivers like openvz, uml, etc as well ) I am using dlopen() and friends to open the VirtualBox library at runtime, is it ok? cause I didn't see any driver doing something like this.
