Hypervisors (Input)¶

VMware ESXi

Must be managed by VMware vCenter ≥ 5.0 unless VDDK is available.

OVA exported from VMware

OVAs from other hypervisors will not work.

VMX from VMware

VMX files generated by other hypervisors will not work.

RHEL 5 Xen

SUSE Xen

Citrix Xen

Citrix Xen has not been recently tested.

Hyper-V

Not recently tested. Requires that you export the disk or use virt-p2v(1) on Hyper-V.

Direct from disk images

Only disk images exported from supported hypervisors, and using container formats supported by qemu.

Physical machines

Using the virt-p2v(1) tool.

Hypervisors (Output)¶

QEMU and KVM only.

Virtualization management systems (Output)¶

OpenStack

Red Hat Virtualization (RHV) 4.1 and up

Local libvirt

And hence virsh(1), virt-manager(1), and similar tools.

Local disk

Guests¶

Red Hat Enterprise Linux 3, 4, 5, 6, 7

CentOS 3, 4, 5, 6, 7

Scientific Linux 3, 4, 5, 6, 7

Oracle Linux

Fedora

SLES 10 and up

OpenSUSE 10 and up

Debian 6 and up

Ubuntu 10.04, 12.04, 14.04, 16.04, and up

Windows XP to Windows 10 / Windows Server 2016

We use Windows internal version numbers, see https://en.wikipedia.org/wiki/List_of_Microsoft_Windows_versions

Currently NT 5.2 to NT 6.3 are supported.

See "WINDOWS" below for additional notes on converting Windows guests.

Guest firmware¶

BIOS is supported for all guest types and hypervisors.

VMware allows you to present UEFI firmware to guests (instead of the ordinary PC BIOS). Virt-v2v can convert these guests, but requires that UEFI is supported by the target hypervisor.

Currently KVM supports OVMF, an open source UEFI firmware, and can run these guests.

Since OVMF support was only recently added to KVM (in 2014/2015), not all target environments support UEFI guests yet:

UEFI on libvirt, qemu

Supported. Virt-v2v will generate the correct libvirt XML (metadata) automatically, but note that the same version of OVMF must be installed on the conversion host as is installed on the target hypervisor, else you will have to adjust paths in the metadata.

UEFI on OpenStack

Not supported.

UEFI on oVirt or RHV

Supported since oVirt/RHV ≥ 4.2 and virt-v2v ≥ 1.39.12.
