<div dir="ltr">I faced with several difficulties / misunderstandings and I hope someone could clarify me (at the moment I use 'virsh' for testing).</div>

<div dir="ltr">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?</div></font></div></blockquote>
</div><div>You can specify an IP address and a netmask like this:<br><a href="http://libvirt.org/formatnetwork.html#elementsAddress" target="_blank">http://libvirt.org/formatnetwork.html#elementsAddress</a><br>Such bridge will be automatically set up.<br>

<div dir="ltr">3) after creating domain via 'virsh # create ovz.xml' i get a new container, but it doesn't work as it should do:<br>
- 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:<br>
</div>
<div dir="ltr">[root@alt-03 ~]# cat /etc/vz/conf/3005.conf | grep NETIF<br>
NETIF="ifname=vzbr0,mac=52:54:00:35:10:6D,host_ifname=veth3005.0,host_mac=52:54:00:35:10:6D"</div></font></div></blockquote></div><div>Short answer: it doesn't work now. Wait for nex libvirt release (libvirt-4.6-alt2). I will try to make it as soon as possible.<br>
