You generally shouldn't install multiple hypervisors on the same
system. I have seen fairly sternly worded warnings against having
VirtualBox and KVM/QEMU installed simultaneously on the same host.
(They probably can _coexist_, but trying to _run_ both at the same
time may well cause issues.) There should be no problems with using
different front-ends for the same hypervisor, however; I regularly use
both virt-manager and the command-line utilities (including
virt-install and virsh) depending on what I need.

I think you can use `qemu-img convert -f vdi -O qcow2` to convert from
a VDI disk image to a QCOW2 or raw disk image, which QEMU/KVM in turn
can use. (qemu-img convert can also convert to and from many other
formats; see the output of qemu-img --help.) Compared to raw disk
images, QCOW2 adds a number of nice features, not least of which disk
snapshots.

In Debian, qemu-img is packaged in qemu-utils (in Bookworm, at least).

Apparently, a OVA is just a tarball of a hard disk image and a XML
file describing the VM. It shouldn't be too difficult to convert the
disk image and then create a similar KVM VM using the information in
the XML file. It looks like there's a tool named virt-v2v which can do
the conversion, although I have never had a need to try it.
