[Libvir] OpenVZ driver enhancements

Hi, I'm glad to make available patches for the OpenVZ driver that provide the following features: * virDomainDefineXML - Defines an OpenVZ domain and does not start it. Takes XML description of the domain as input. * virDomainCreateLinux - Starts a domain based on the provided XML description. There is no way to start a domain in OpenVZ without defining it. So, it is defined anyway, as of now. :-( There may be a way to get around this. We are looking into it. As of now, treat this as define + start. * virDomainUndefine - removes domain from OpenVZ management. Since OpenVZ manages the domain's root file system, it is also lost. This behaviour is different from Xen. The XML Format for OpenVZ: -------------------------- <domain type='openvz'> <name>108</name> <uuid>8dea22b31d52d8f32516782e98ab8fa0</uuid> <container> <filesystem> <template>fedora-core-3-i386-minimal</template> <quota level = 'first'>123</quota> <quota level = 'second' uid = '500'>534</quota> </filesystem> <network> <ipaddress>192.168.1.108</ipaddress> <hostname>fedora-minimal</hostname> <gateway>192.168.1.1</gateway> <nameserver>192.168.1.1</nameserver> <netmask>255.255.255.0</netmask> </network> <profile>vps.basic</profile> </container> </domain> The name is the VPS "ID". The VPS ID is not temporary in OpenVZ as in Xen. The "<template>" tag in the "<filesystem>" section tells libvirt which OS template cache to use to create the VPS file system. Quota is not implemented as yet. First and second level quotas are intended to be supported. The "<profile>" tag must be a valid profile name from which VPS parameter are inherited. Other things, I guess are self explanatory. Other issues: ------------- * Moved some static declarations from the header to the .c files. * Fixed a small bug that cause libvirtd to crash on remote client exit. Patches are against CVS head.
