Abstract

Virtual machine (VM) management using a group name. By associating VM registration information with a group name, all VMs running off a single physical machine image can be managed (e.g., blocked or unblocked) simultaneously. A service component captures registration information (e.g., IP address-VM name pair) between a virtual machine and a name server. The IP address-VM name pair is recorded (or stored) in the name server database. Based on the VM pair, a record component generates a group name, and stores the VM pair in association with the group name in the name server database. Blocking of the group name then blocks all VMs associated with the group name. Moreover, queries against the group name will then expose all operational VMs for that host. Updates to the group name record can be made based on registration and deregistration of VMs for a given host machine.

Claims

1. A computer-implemented system for virtual machine management, comprising:

a service component for capturing registration information between a first virtual machine and a name server, the first virtual machine hosted on a physical machine; and

a record component for generating a group name, and storing the registration information in association with the group name.

2. The system of claim 1, wherein the service component executes on the address server or the physical machine.

3. The system of claim 2, wherein the address server is a dynamic host configuration protocol (DHCP) server.

4. The system of claim 1, wherein the registration information captured by the service component is for registering the first virtual machine to the name server.

5. The system of claim 1, wherein the registration information captured by the service component is for deregistering the first virtual machine from the name server.

6. The system of claim 1, wherein the first virtual machine executes according to a first operating system and a second virtual machine of the physical machine executes according to a same or different operating system, the record component generates the group name in association with both the first virtual machine and the second virtual machine.

7. The system of claim 1, wherein the first virtual machine executes according to a first operating system and a second virtual machine of the physical machine executes according to a second operating system, the record component generates the group name in association with the first virtual machine and a second group name in association with the second virtual machine.

8. The system of claim 1, wherein the address server is a DHCP server that registers the group name with a domain name server (DNS).

9. The system of claim 1, wherein the registration information includes a virtual machine name mapped to an IP address, and a host machine name mapped to the group name in a DNS.

10. A computer-implemented method of managing virtual machines, comprising:

intercepting name-address information of virtual machines of a host machine;

generating a network-level group name for the host machine;

storing the group name on a name service;

associating the host machine and the virtual machines with the group name; and

managing the virtual machines based on the group name.

11. The method of claim 10, further comprising storing a host machine identifier and corresponding identifiers for the virtual machines in association with the group name.

12. The method of claim 11, further comprising automatically updating the identifiers of the virtual machines associated with the stored group name based on a change in status of one of the virtual machines.

13. The method of claim 10, further comprising querying the group name based on a group-name/IP mapping.

14. The method of claim 10, further comprising blocking one or more of the virtual machines based on the group name.

15. The method of claim 10, further comprising generating a service locator resource record on the name server that includes VM group names for the host name and optionally VM names for a VM group name.

16. The method of claim 15, further comprising querying the service locator resource record to learn of registered VM group names and VM names.

17. The method of claim 10, further comprising generating an address record on the name server that maps the group name to one or more IPv4 or IPv6 addresses.

18. The method of claim 17, further comprising searching the address record to determine the virtual machines associated with the host machine.

19. The method of claim 10, further comprising blocking one or more of the virtual machines based on a common operating system image.

20. A computer-implemented system, comprising:

computer-implemented means for intercepting name-address information of virtual machines on a host machine;

computer-implemented means for generating a network-level group name for the host machine;

computer-implemented means for registering the group name with a name service; and

computer-implemented means for associating the host machine and the virtual machines with the group name.
