Hello all,

We are once again looking to increase the minimum and next minimum
versions of libvirt and QEMU in the libvirt virt driver.

These were previously increased late in the Victoria cycle:

MIN_LIBVIRT_VERSION = (5, 0, 0)
MIN_QEMU_VERSION = (4, 0, 0)

NEXT_MIN_LIBVIRT_VERSION = (6, 0, 0)
NEXT_MIN_QEMU_VERSION = (4, 2, 0)

libvirt: Bump MIN_{LIBVIRT,QEMU}_VERSION and NEXT_MIN_{LIBVIRT,QEMU}_VERSION
https://review.opendev.org/c/openstack/nova/+/746981

I am now proposing the following updates to these versions in Wallaby:

MIN_LIBVIRT_VERSION = (6, 0, 0)
MIN_QEMU_VERSION = (4, 2, 0)

NEXT_MIN_LIBVIRT_VERSION = (7, 0, 0)
NEXT_MIN_QEMU_VERSION = (5, 2, 0)

libvirt: Bump MIN_{LIBVIRT,QEMU}_VERSION and NEXT_MIN_{LIBVIRT,QEMU}_VERSION
https://review.opendev.org/c/openstack/nova/+/754700

libvirt v6.0.0 and QEMU 4.2.0 being supported by the three LTS releases
supported by the Wallaby release of OpenStack [1][2].

libvirt v7.0.0 and QEMU 5.2.0 being slightly aspirational for the next
minimum versions at this point but given current releases for both
projects they seem appropriate for the time being.

Please let me know ideally in the review if there are any issues with
this increase.
