To workaround this issue, manually reconfigure the static settings on the new
virtual network adapter created in the parent partition.
To prevent this issue, it is recommended that you set static network settings
on the parent partition network adapters only after creating the required
virtual networks.
Remote Network Connection May be Lost When Creating a Hyper-V Virtual Network
When you bind an External Virtual Network is to a physical network adapter,
the remote network connections may be lost temporarily during the virtual
network creation process. The issue occurs if the remote network connection
to the Hyper-V host uses the physical network adapter on which the new
virtual network was bound to.
This feature is working as designed. In most cases, the remote connection is
automatically re-established. To workaround this issue, it is recommended
that you dedicate a specific network adapter in the parent partition strictly for
managing the system. You must not bind the Management network adapter to
any Hyper-V virtual network. Also, you must make remote connections, if any,
to the parent partition via the IP address of this Management NIC.
