Chapter 7: Migrating and Importing Virtual Machines

Use the VirtualCenter 2.5 Consolidation feature. The Consolidation feature of VirtualCenter 2.5 offers a simplified utility for creating a consolidation plan for small- and medium-sized businesses.

Master It Your company has 27 physical servers that it has identified as virtualization candidates. You need to provide a documented effort for determining which systems are ideal candidates and where on the four-node cluster the virtual machine should run.

Solution Use the VirtualCenter 2.5 Consolidation feature to monitor resource utilization on the 27 hosts. Once the confidence level is high, review the consolidation plan to see which servers are good candidates for virtual machines and which ESX Server hosts are best for running the converted system.

Perform physical-to-virtual migrations of running computers. A hot migration, or hot clone, is the conversion of a running computer into a virtual machine. The hot cloning process is ideal for systems with relatively static data sets to ensure time-consistent conversions of the target computer.

Master It Your company's business hours are 8:00 ~AM to 6:00 ~PM. There are four physical servers that function as domain controllers. You want to convert three of them to virtual machines running in your new three-node ESX Server cluster.

Solution Perform a hot clone of the three domain controllers during nonbusiness hours. Once the conversion is complete, power off the physical computers and power on the virtual machines.

Master It You have an existing virtual machine that has a 10GB C drive with only 1MB of space remaining. You need to provide an additional 20GB of space to the C drive.

Solution Use the VMware Converter to perform a virtual-to-virtual migration. During the migration process, add 20GB of space to the C:volume of the new virtual machine. After the migration, decommission the old virtual machine.

Perform physical-to-virtual migrations of computers that are powered off. A cold migration, or cold clone, is the conversion of a computer into a virtual machine while booted from the VMware Converter boot CD. The cold cloning process is ideal for systems that rely on frequently changing data sets, since the data cannot be modified during the conversion process.

Master It Your company has a computer that runs Microsoft SQL Server 2005. The IT staff has identified the system as a good target for becoming a virtual machine. You need to plan the conversion of the SQL Server 2005 computer into a virtual machine.

Solution Schedule a planned outage during nonbusiness hours to perform a cold clone of the SQL Server 2005 computer.

Import virtual appliances. The ability to import virtual appliances is a new feature of VirtualCenter 2.5. Appliances can be pulled directly from VMware or can be imported from a local file or URL.

Master It You need to deploy the remote command-line management tool as a virtual appliance in your VirtualCenter 2.5 inventory.

Solution Use the Import Virtual Appliance feature to import the virtual machine directly from the VMware website.
