In this case the source guest is always left unchanged. In this mode, the converted guest is created as a libvirt guest. You will see an error:. Typical output looks like this: It contains more detail for any errors caused by the oVirt GUI.

When using -o libvirtyou may need to run virt-v2v as root so that it can write to the libvirt system instance ie. Virt-v2v will read the ova manifest file and check the vmdk volumes for validity checksums as well as analyzing the vort-v2v file, and then convert the guest.

This version of virt-v2v does not attempt to install any new kernels. There is no way for virt-v2v to upload directly to Cinder https: Note I am running this command as non-root:.

This is the method used by virt-p2v 1 behind the scenes. For more information see virt-v2v-output-rhv 1. For -o openstack virt-v2v-output-openstack 1 only, set optional OpenStack authentication.

Older versions of virt-v2v could install these drivers for certain Linux guests. Typical output looks like this: Secondly use the option in conjunction with other options to make the regular program output more machine friendly.


It is required if you intend to use the –firstboot or –firstboot-command options with Windows guests.

In that case it is assumed that a third-party tool has created the target VM in the supported KVM-based hypervisor based on the source VM configuration and contents, but using virtual devices more appropriate for KVM e.



There is also a companion front-end called virt-p2v 1 which comes as an ISO, CD or PXE image that can be booted on physical machines to virtualize those machines physical to virtual, or p2v. When using this output mode, you can also specify the –qemu-boot option which boots the guest under qemu immediately.

Importing VMs to KVM with virt-v2v

You can mount the Export Storage Domain yourself, vitt-v2v point -os to the mountpoint. Glance and sparseness Glance image upload doesn’t appear to correctly handle sparseness. This is not necessary for Linux guests, as virt-v2v is able to remove VMware tools. If the guest has multiple disks, then the first assumed to be the system disk will have the name of the guest, and the second and subsequent data disks will be called ” guestname-disk2″” guestname-disk3″ etc.

If the output of the program is redirected to a file, ANSI colour sequences are disabled unless you use this option. Tagged as centoslibguestfsrhelrpmv2vvirt-toolsvirt-v2vvirtualization. When using this output mode, you can also specify the –qemu-boot option which boots the guest under qemu immediately.

If this directory is present, then virtio drivers for Windows guests will be found from this directory and installed in the guest during conversion. Migrate the guest to this volume using -o local. For some older Linux distributions, this means installing a kernel from the table below:. Remote libvirt connections will not work.


Although this is not strictly necessary, and the guest will still be able to run, if you don’t do this then the converted guest will complain on every boot. To do this, virt-v2v issues a non-destructive fstrim 8 operation. Virt-v2v can be run in a virtual machine.

You can mount the Export Storage Domain yourself, and point -os to the mountpoint. Guest network interface s are connected to the target network called “ovirtmgmt”. For -o libvirtthis is a libvirt directory pool see virsh pool-list or pool UUID.

You can specify the -oa preallocated option, where virt-v2v will try to ask the target hypervisor to fully preallocate the target disks of the guest. The NFS export must be mountable and writable by the user and cirt-v2v running virt-v2v, since the virt-v2v program has to actually mount it when it runs.

Virt-v2v should be able to copy guest data at gigabit ethernet speeds or greater.
