vCPU Hot(un)plug in libvirt
In scalable cloud virtualized environments, we often increase/decrease the number of virtual CPUs (vCPUs) of a guest virtual machine (VM) to handle dynamic work load requirements to save resources and reduce costs. This article delves into how libvirt performs these operations behind the scenes for a running guest VM.
Realtime and cgroups—a cautionary tale
Realtime cgroups for Linux can provide advantages, as discussed in this Realtime and cgroups blog. By grouping critical realtime tasks, an application's performance can receive a notable boost and budgeting the realtime quota among the tasks—can make it easier to manage the CPU cycle allocations. However, elevating CPU-intensive tasks to realtime or over/under allocating the realtime budget, can lead to system stall or slowdowns. Proper tuning of the realtime global and cgroup settings can cater to specialized applications and to general systems, providing them with benefits of realtime and cgroups. |
