Well, I guess it's there, mostly because they didn't have to do anything new, it's part of KVM/libvirt and more inherited than added. The main reason I "don't see it coming" is that may create more problems than it solves. To my understanding K8 is all about truly elastic workloads, including "mobility" to avoid constraints (including memory overcommit). Mobility in quotes, because I don't even know if it migrates containers or just shuts instances down in one place and launches them in another: migration itself has a significant cost after all. But if it were to migrate them (e.g. via CRIU for containers and "vMotion" for VMs) it would then to also have to understand (via KubeVirt), which devices are tied, because they use a device that has too big a state (e.g. a multi-gig CUDA workloads), a hard physical dependence (e.g. USB with connected devices) or something that could move with the VM (e.g. SR-IOV FC/NIC/INF with a fabric that can be re-configured to match or is also virtualized). A proper negotiation between the not-so-dynamic physically available assets of the DC and the much more dynamic resources required by the application are the full scope of a virt-stack/k8 hybrid, encompassing a DC/Cloud-OS (infrastructure) and K8 (platform) aspects. While I'd love to have that, I can see how that won't be maintained by anyone as a full free-to-use open-souce turn-key solution. _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/OPAKEXBS4LZSG2HIU3AWGJJCLT22FFGF/
