Document URL: https://docs.openshift.com/container-platform/4.4/cnv/cnv_live_migration/cnv-live-migration.html Section Number and Name: Describe the issue: In order to use LiveMigration the VM has to be deployed with RWX volume. Defaults in openshift-cnv kubevirt-storage-class-defaults are configured to provide RWO volumes so LiveMigration doesn't work by default. Suggestions for improvement: We should explain this setting in our CNV documentation and mention that in order to override this default setting for the specific StorageClass they should update the config map, for an instance: $ export STORAGE_CLASS="nfs" $ oc patch -n openshift-cnv cm kubevirt-storage-class-defaults -p '{"data":{"'${STORAGE_CLASS}'.accessMode":"ReadWriteMany"}}' Additional information:
Check with the doc, already add change RWO to RWX for migration, move to verified.
I review the test build, no other comments and can move this to verified.
