[libvirt] OpenVZ: Still the same macs for host and domain veth devices.

Hi, guys.
During domain creation from xml like this:
<domain type="openvz" id="3005">
<name>3005</name>
<memory>131072</memory>
<currentMemory>131072</currentMemory>
<vcpu>1</vcpu>
<os>
<type>exe</type>
</os>
<devices>
<filesystem type="template">
<source name="altlinux-4.0"/>
<target dir="/"/>
</filesystem>
<interface type="bridge">
<source bridge="vzrb0"/>
<target dev="veth3005.0"/>
</interface>
</devices>
i get veth3005.0 on a HW node connected to virtual bridge vzbr0 and eth0 inside a container. So that annoying bug with confused <source> and <target> tags seems to be fixed. Thanks for that!
But mac generation still seems to be an issue, caz mac of eth0 and veth3005.0 are the same:
[root at alt-03 ~]# cat /etc/vz/conf/3005.conf | grep NETIF
NETIF="ifname=eth0,bridge=vzbr0,mac=52:54:00:97:72:8E,host_ifname=veth3005.0,host_mac=52:54:00:97:72:8E"
So when i connect two containers via bridge they cannot "talk" to each other due to macs conflict. Can something be done to improve mac generation behaviour?
Version I use at the moment:
[root at alt-03 ~]# rpm -qa | grep libvirt
libvirt-python-0.5.0-alt1
libvirt-0.5.0-alt1
libvirt-devel-0.5.0-alt1
And one more not an OpenVZ-specific question: I am working on a project using python and python API bindings in libvirt. I don't see a python method for virNetworkCreateXML:
>>> dir(libvirt.virConnect.networkCreateXML)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: class virConnect has no attribute 'networkCreateXML'
There are two methods for virNetworkDefineXML and virNetworkCreate separately:
>>> dir(libvirt.virConnect.networkDefineXML)
['__call__', '__class__', '__cmp__', '__delattr__', '__doc__', '__get__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__str__', 'im_class', 'im_func', 'im_self']
>>> dir(libvirt.virNetwork.create)
['__call__', '__class__', '__cmp__', '__delattr__', '__doc__', '__get__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__str__', 'im_class', 'im_func', 'im_self']
Is networkCreateXML missed?
