To restore individual files and folders from file systems other than Microsoft Windows, you can use the multi-OS File-Level Restore wizard. To restore files from VM guest OS, Veeam Backup & Replication uses a proxy appliance. The proxy appliance is a helper VM running a stripped down Linux kernel that has a minimal set of components. When the appliance is booting up you may open a console and see the following message:
Unable to obtain settings by DHCP for interface eth0: ... No such device
This is a bug in the Linux kernel of the appliance that occurs only in Hyper-V 2008 R2.
This is known issue which will be fixed in the next version of Veeam Backup & Replication.
There are two possible workarounds currently :
Update your Hyper-V server to Windows 2012 R2
Use Instant Recovery, connect VM to an isolated network and retrieve needed files in any convenient way
