There haven’t been too many updates around here for a while, and that’s for a very good reason: I’ve been “heads down” writing the new versions of virt-v2v and virt-p2v, our tools for converting VMware and Xen virtual machines, or physical machines, to run on KVM.
The new virt-v2v [manual page] can slurp in a guest from a local disk image, local Xen, VMware vCenter, or (soon) an OVA file — convert it to run on KVM — and write it out to RHEV-M, OpenStack Glance, local libvirt or as a plain disk image.
It’s easy to use too. Unlike the old virt-v2v there are no hairy configuration files to edit or complicated preparations. You simply do:
$ virt-v2v -i disk xen_disk.img -o local -os /tmp
That command (which doesn’t need root, naturally) takes the Xen disk image, which could be any supported Windows or Enterprise Linux distro, converts it to run on KVM (eg. installing virtio drivers, adjusting dozens of configuration files), and writes it out to
To connect to a VMware vCenter server, change the
-i options to:
$ virt-v2v -ic vpx://vcenter/Datacenter/esxi "esx guest name" [-o ...]
To output the converted disk image to OpenStack glance, change the
-o options to:
$ virt-v2v [-i ...] -o glance [-on glance_image_name]
Coming up: The new technology we’ve used to make virt-v2v much faster.
