3.3. Converting a virtual machine
Once you have prepared to convert the virtual machines, use
virt-v2vto perform the actual conversions. This section provides the steps to convert the virtual machines, and the command syntax for
Note that conversions are resource intensive processes that require copying the whole disk image for a virtual machine. In typical environments, converting a single virtual machine takes approximately 5-10 minutes. In Example 3.4, “Typical virt-v2v conversion time” a virtual machine with a single 8GB disk is copied over SSH on a 1GigE network on three-year-old consumer hardware:
Example 3.4. Typical virt-v2v conversion time
win2k3r2-pv-32.img: 100% [===========================================]D 0h02m57s virt-v2v: win2k3r2-pv-32 configured with virtio drivers.
The size of the disk to be copied is the major factor in determining conversion time. For a virtual machine on average hardware with a single disk of 20GB or less, a conversion usually takes less than 10 minutes.
3.3.1. Converting a local virtual machine using virt-v2v
virt-v2vconverts virtual machines from a foreign hypervisor to run on KVM, managed by libvirt. The general command syntax for converting machines to run on KVM, managed by libvirt is:
virt-v2v -i libvirtxml -op pool --bridge bridge_name guest_name.xml virt-v2v -op pool --network netname guest_name virt-v2v -ic esx://esx.example.com/?no_verify=1 -op pool --bridge bridge_name guest_name
