I want to have a KVM virtualized server with few VMs (with different Guest OSs) in production. Now when I want to install kernel/package updates for the host machine, how to restart the hypervisor without corrupting any VM data? (when there are some SQL/disk write is happening on the VMs)
I know this is a very simple question but I mainly want to know if KernelCare should be the best option for the host to keep updated. I am looking at no data corruption/any such serious issues but minimum interruption for the VMs are OK (in application hosting server environment).
