The requirement to specify the parent class type makes the macro
harder to use and easy to misuse (silent bugs can be introduced
if the wrong struct type is specified).
Simplify the macro by just not declaring any class struct,
allowing us to remove the class_size field from the TypeInfo
This converts existing DECLARE_OBJ_CHECKERS usage to
OBJECT_DECLARE_TYPE when possible.

# Backpropagation
Whenever a partial VM configuration is submitted to libvirt, any missing
information is automatically filled in to obtain a configuration that's
complete enough to guarantee long-term guest ABI

How is the QEMU process isolated from the host and from other VMs?

# NUMA pinning
KubeVirt doesn't currently implement NUMA pinning due to Kubernetes
limitation.
## Kubernetes Topology Manager
Allows aligning CPU and peripheral device allocations by NUMA node.
Many limitations:

# CPU pinning
As is the case for many of KubeVirt's features, CPU pinning is
partially achieved using standard Kubernetes components: this both
reduces the amount of new code that has to be written and guarantees

# Components
This document describes the various components of the KubeVirt
architecture, how they fit together, and how they compare to the
traditional virtualization architecture (QEMU + libvirt).

Service meshes (such as [Istio][], [Linkerd][]) typically expect

separate user namespace. Network namespaces might be

# Hotplug
In Kubernetes, pods are defined to be immutable, so it's not possible
to perform hotplug of devices in the same way as with the traditional
virtualization stack.
This limitation is a result of KubeVirt's guiding

Hello there!
Several weeks ago, a group of Red Hatters working on the
virtualization stack (primarily QEMU and libvirt) started a
conversation with developers from the KubeVirt project with the goal
of better understanding and documenting the interactions between the
two.
Specifically, we were
