[libvirt] OpenVZ capabilites in LibVIRT

Hello! I'm trying to link OpenVZ with LibVirt in my test environment. There are: [root@alt-03 /]# uname -r 2.6.18-ovz-smp-alt23.M40.3 [root@alt-03 /]# vzctl --version vzctl version 3.0.23 [root@alt-03 /]# rpm -qa | grep libvirt libvirt-0.4.6-alt1 libvirt-python-0.4.6-alt1 libvirt-devel-0.4.6-alt1 The task is to create several isolate virtual networks with several domains inside, like: ve-01 --- vzrb0 -- ve-02 | | ve-03 ve-11 --- vzbr1 -- ve-12 | | ve-13 and so on ... Here is XML definition for 1st network: <network> <name>Private</name> <bridge name="vzbr0" stp='off' forwardDelay='0'/> </network> and the following one for 1st domain: <domain type="openvz" id="3005"> <name>3005</name> <memory>131072</memory> <currentMemory>131072</currentMemory> <vcpu>1</vcpu> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <os> <type>exe</type> </os> <devices> <filesystem type="template"> <source name="altlinux-4.0"/> <target dir="/"/> <quota type="size" max="10000"/> <quota type="inodes" max="200000"/> </filesystem> <interface type='bridge'> <source bridge='vzbr0'/> </interface> </devices> </domain> I faced with several difficulties / misunderstandings and I hope someone could clarify me (at the moment I use 'virsh' for testing). 1) after creating network via 'virsh # net-create network.xml' i get vzbr0 bridge in down state and have to make ip up manually. Is there any way to automatically make it up? 2) there is a default network "Default" with enabled 'Autostart'. Is there any way to remove this network completely? 3) after creating domain via 'virsh # create ovz.xml' i get a new container, but it doesn't work as it should do: - at first, it has 'vzbr0' veth interface inside and its pair on a HW node is added into default bridge vmbr0. I believed tag <source bridge='vzbr0'/> should point to a bridge name on a HW node, but instead it created veth interface with such name. In openvz config file for created domain i see this: [root@alt-03 ~]# cat /etc/vz/conf/3005.conf | grep NETIF NETIF="ifname=vzbr0,mac=52:54:00:35:10:6D,host_ifname=veth3005.0,host_mac=52:54:00:35:10:6D" There is no any info about bridge. So by default veth3005.0 links with vmbr0. - secondly, if you look at that NETIF string, you will see, that 'host_mac' is equal to 'mac'. Because of this two domains cannot contact with each other via the same bridge. Is there any way to point veth interfaces to correct bridge, assign them corrects macs and names? 4) Is there any way to specify config file for created domain like it can be done via 'vzctl create <ID> --oostemplate <templname> --config <confname>'? 5) Is there any way to destroy domain completely like it can be done via 'vzctl destroy <ID>'? 6) Where does libvirt store info about already created domains? I can't create a new domain with ID 3005 after I completely destroy previous one via 'vzctl destroy 3005'. 7) Is there any way to publish domain's console on a host system so that I can connect via telnet to HW node on some TCP/4567 and get into domain's console? 8) Does libvirt use some OpenVZ bindings or simply executes vzctl and other stuff?
