Why can't a CentOS 7 virtual machine go online?

Good afternoon.
There is a Windows Server 2012R2, Hyper-V is raised on it.
The iron server has two network cards that are combined into a Nic-Team using Windows Server'a
. The firewall is turned off.
A virtual machine has been created on which CentOS 7 is installed and when you try to "yum update" or "ping 8.8.8.8" - nothing happens, i.e. such a feeling that "there is no Internet." Although the rest of the virtual machines located nearby everything is fine with the grid.
IPTables is disabled (everything is allowed).
If to do with virtual CentOS "ping 192.168.???.???", where ??? any address of the local network - then pings go. Also, the CentOS virtual machine itself is pinged from LAN and from the Internet.
Tell me, what could be the reason?
Thanks in advance.

Everyone figured out the reason. The reason is simple - the fool himself))
Everything turned out to be corny - the virtual centos received an IP address from a group of IP addresses that are prohibited from accessing the Internet)))

@firedragon

what type of connection?
I have something like this:
The default switch is connected only to the microtick virtual router The local switch is connected to virtual machines
. This made it possible not to lose connection when raising the VPN
