You know the workload associated with virtualisation host patching is tremendous.

It may not be a problem if you only have 2 or 3 machines, but when it comes to 10+ hosts, the process can take at least several hours (depending on the actual load on each node and network conditions). QEMUCare Live Patching applies security updates to running VMs and eliminates the need for a live migration process.

*But if you don’t mind the workload, enjoy TuxCare comprehensive guide to QEMU patching.

You have to ensure uninterrupted performance of the infrastructure for the developers running VMs on QEMU or KVM on the hosts.

This is on top of keeping the infrastructure safe from vulnerabilities by making sure your developers follow best security practices when interacting with your systems.

QEMUCare will let you shift your focus from patching and securing the virtualisation platform to other areas, knowing that the hosts will no longer be at risk from known exploits.
