None of VMs I tried to install can't reach internet. I have Xensever 6.2 installed on a server with single NIC, which can be accessed via 2 public IPs. XenServer can ping google.com and seems to be configured correctly.
Here's ifconfig output

I installed vm with network attached to it and it can't access internet. Do I need to configure the guest vm the special way, and if so how it can be done.

The problem was that Hetzner dropped any packets coming from my randomly assigned mac addresses. So it did't work unless I assigned real macs to my VM.
