the libvirt and Qemu versions on Ubuntu 14.04 cannot meet some functional requirements. I want to upgrade them to a newer version, for example, I use the version on 18.04, but I don"t want to upgrade the whole system. What should I do?

support for new versions of application software can usually be achieved by upgrading the kernel.
it is recommended that you test whether it is feasible on a virtual machine before actual operation.
the simplest instruction set that I always use for kernel upgrade / downgrade is a post by the ubuntuforums.org user's name lykwydchykyn:
here: http://kernel.ubuntu.com/~ker.
download 3 (maybe 4) deb installation package to a folder:
linux-headers-VERSION-NUMBER_all.deb
linux-headers-VERSION-NUMBER_amd64.deb
linux-image-VERSION-NUMBER_amd64.deb
linux-image-extra-VERSION-NUMBER_amd64.deb-sharp if available
install the debit package (gdebi is still available) with any package manager used, or use the following command:
cd / path/to/folder/where/you/put/the/debs
sudo dpkg-I * .deb
after the kernel upgrade is complete, you can install the corresponding new version of the software.
