4.3.2. Converting a virtual machine
Once you have prepared to convert the virtual machines, use
virt-v2v to 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 4.2, “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 4.2. 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.
virt-v2v converts virtual machines from a foreign hypervisor to run on Red Hat Enterprise Virtualization. The general command syntax for converting machines to run on Red Hat Enterprise Virtualization is:
virt-v2v -i libvirtxml -o rhev -os storage.example.com:/exportdomain --network rhevm guest_name.xml virt-v2v -o rhev -os storage.example.com:/exportdomain --network rhevm guest_name virt-v2v -ic esx://esx.example.com/?no_verify=1 -o rhev -os storage.example.com:/exportdomain --network rhevm guest_name
A full specification of the parameters which can be used with
virt-v2v is available in Section 7.1, “virt-v2v Parameters”.
virt-v2v does not support converting a virtual machine with more than four IDE disks to Red Hat Enterprise Virtualization. Attempting to convert a virtual machine with five or more disks will fail.
