Stephen Finucane 740e6f09bf libvirt: Enable 'vmcoreinfo' feature by default
The 'vmcoreinfo' feature flag enables the vmcoreinfo device, which will
"create a fw_cfg entry for a guest to store dump details, necessary to
process kernel dump with KASLR enabled and providing additional kernel
details." [1] It's supported since libvirt 3.10 and QEMU 2.11, both of
which are lower than our minimum versions.

When using the libvirt virt driver with the QEMU or KVM backends, instances
will now be created with the *vmcoreinfo* feature enabled by default. This
creates a fw_cfg entry for a guest to store dump details, necessary to
process kernel dump with KASLR enabled and providing additional kernel
details. For more information, refer to the `libvirt`__ documentation.
