向托管公司(Fasthosts)提供MAC地址的KVM

Question

为了允许流量通过我的KVM网络被路由，我的托管公司想知道MAC地址。设置它的方式是我的VM使用了与主机不同的IP。我有网桥和虚拟机(使用我从托管公司获得的第二个IP )，它们似乎都有mac地址。那么MAC地址主机公司会看到什么(通过主机从我的VM中出来)。第二个IP只设置在VM上，现在是其他IP。

他们还想知道IP，我在VM上设置的二级IP？

主机是CentOS，客人是Ubuntu16.04。

法西斯主义者的支持有点卢布，所以不能得到他们的帮助。

我的VM有一个MAC地址，has有以下内容：

Answer 1

这是我需要给他们的VM的MAC。实际上他们比正常人更有帮助。
