 * {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://issues.redhat.com/browse/CNV-33835[*CNV-33835*])
 ** As a workaround, use user accounts rather than service accounts because user account tokens are not bound to a specific pod.

-// cnv-61957 - GPU devices should not be shown in UI
-* GPU devices appear in the *Hardware Devices* list for s390x VMs, but GPU support is not available for s390x architecture. You can disregard these list entries. (link:https://issues.redhat.com/browse/CNV-61957[CNV-61957])

 // ocpbugs-51113 - ballooning call traces
 * When you create a VM by using {op-system-base-full} container disk images for s390x architecture, call traces referencing `virtio_balloon` free page reporting print to the VM console. This is due to a kernel bug. (link:https://issues.redhat.com/browse/OCPBUGS-51113[OCPBUGS-51113])
 ** As a workaround, disable memory ballooning for the VM by adding the following parameter to the VM YAML configuration: `spec.domain.devices.autoattachMemBalloon: false`.
 +
 You can also disable free page reporting of memory ballooning for all new VMs. To do so, edit the `HyperConverged` CR and add the parameter `spec.virtualMachineOptions.disableFreePageReporting: true`.
 
-// cnv-56889 - boot mode
+// CNV-56889: Matan indicated this will remain in 4.20 but is targeted for 4.21
 * VMs based on s390x architecture can only use the *IPL* boot mode. However, in the {product-title} web console, the *Boot mode* list for s390x VMs incorrectly includes *BIOS*, *UEFI*, and *UEFI (secure)* boot modes. If you select one of these modes for an s390x-based VM, the operation fails. (link:https://issues.redhat.com/browse/CNV-56889[CNV-56889])
-
-// cnv-56890 - threads
-* In the {product-title} web console, it is erroneously possible to define multiple CPU threads for a VM based on s390x architecture. If you define multiple CPU threads, the VM enters a `CrashLoopBackOff` state with the `qemu-kvm: S390 does not support more than 1 threads` error.
