--- features: - | 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. __ https://libvirt.org/formatdomain.html#hypervisor-features
