Network Access Control Policy for Virtual Machine Migration
First Claim
1. A method comprising:
- at a first device in a network, receiving a message from a second device comprising information configured to request a migration of a virtual machine to the first device;
sending a message to the second device comprising information configured to request information about the operating conditions of the virtual machine;
receiving a response to the request comprising information about operating conditions of the virtual machine;
determining whether the information in the response complies with a network access control policy; and
in response to determining that the information complies with the network access control policy, permitting the virtual machine to migrate, or otherwise denying the virtual machine migration request.

Abstract
Techniques are provided to apply a network access control policy to a virtual machine (VM) migration before allowing the VM to migrate from one server to another server. At a first device in a network, a message is received from a second device, the message comprising information configured to request a migration of a virtual machine to the first device. A request is sent to the second device configured to request information about the operating conditions of the VM. A response to the request is received comprising information about the VM'"'"'s operating conditions. A determination is made as to whether the information in the response complies with a network access control policy. In response to determining that the information complies with the network access control policy, the virtual machine is permitted to migrate, or otherwise the virtual machine migration request is denied.

12. A method comprising:
-
sending a message to a first device from a second device, the message comprising information configured to request migration of a virtual machine to the first device; receiving a request message from the first device comprising information configured to request information about the operating conditions of the virtual machine; sending a response to the request message, the response comprising information about operating conditions of the virtual machine; receiving a message from the first device comprising information configured to grant or deny the virtual machine migration request; in response to receiving a grant message, migrating the virtual machine to the first device; and in response to receiving a denial message, canceling migration of the virtual machine to the first device. - View Dependent Claims (13, 14, 15)
