* If your {product-title} cluster uses OVN-Kubernetes as the default Container Network Interface (CNI) provider, you cannot attach a Linux bridge or bonding device to a host's default interface because of a change in the host network topology of OVN-Kubernetes. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1885605[*BZ#1885605*])
** As a workaround, you can use a secondary network interface connected to your host, or switch to the OpenShift SDN default CNI provider.

* {VirtProductName} links a service account token in use by a pod to that specific pod. {VirtProductName} implements a service account volume by creating a disk image that contains a token. If you migrate a VM, then the service account volume becomes invalid. (link:https://bugzilla.redhat.com/show_bug.cgi?id=2037611[*BZ#2037611*])
** As a workaround, use user accounts rather than service accounts because user account tokens are not bound to a specific pod.

* If you configure the `HyperConverged` custom resource (CR) to enable mediated devices before drivers are installed, enablement of mediated devices does not occur. This issue can be triggered by updates. For example, if `virt-handler` is updated before `daemonset`, which installs NVIDIA drivers, then nodes cannot provide virtual machine GPUs.
