Live-patching QEMU with QEMUCare

Rebooting is a pain, and in some organizations, downright tedious. Shuffling virtual machines between hosts in a cluster is even more tedious, and when it's time to install patches, that's what many administrators are forced to do. In this video, I check out QEMUCare, which aims to live-patch QEMU to avoid VM shuffling. In particular, we'll look at installing ePortal (which deploys the patches) and also an example scenario. # Time codes 00:00 - Intro 03:29 - Test environment overview, and minimum requirements for eportal 05:25 - Installing ePortal on a VM (required for QEMUCare) 11:53 - Setting up a feed in ePortal 13:07 - Creating an activation key 14:15 - Installing KernelCare 17:24 - Registering a server with eportal 18:02 - Vulnerability patch example # Video-specific Links ?
