I don't know how well QEMU/KVM/libvirt handle other disk images, like
from VMware.
I have done it.

Converting OVA for use with KVM / QCOW2
The OVA file is nothing more than a TAR archive, containing the .OVF and
.VMDK files. Easy!
Using Evergreen ILS for example:
~ $ file Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ova: POSIX tar archive (GNU)
I'ts possible to use the tar command to list the contents
~ $ tar -tf Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ovf
Evergreen_trunk_Squeeze-disk1.vmdk
Simply extract those things...
~ $ tar -xvf Evergreen_trunk_Squeeze.ova
Evergreen_trunk_Squeeze.ovf
Evergreen_trunk_Squeeze-disk1.vmdk
Now take a look at the created files The OVF XML file describes the
image, it makes for some interesting reading about the expectations of
the running environment.
~ $ file Evergreen_trunk_Squeeze*
Evergreen_trunk_Squeeze-disk1.vmdk: VMware4 disk image
Evergreen_trunk_Squeeze.ova: POSIX tar archive (GNU)
Evergreen_trunk_Squeeze.ovf: XML document text
Recent versions of qemu are able to run directly from the VMDK file, buy
why do that? Use QCOW2, it's better. Execute: qemu-img -h and the last
line of output shows the supported formats.
~ $ qemu-img -h |tail -n1
Supported formats: raw cow qcow vdi vmdk cloop dmg bochs vpc vvfat qcow2
parallels nbd blkdebug sheepdog host_cdrom host_floppy host_device file
Now actually convert it, this may take some time.
~ $ qemu-img convert -O qcow2 Evergreen_trunk_Squeeze-disk1.vmdk
Evergreen_trunk_Squeeze.qcow2
