[ovirt-users] can't run VM

Hi, I created VM on ovirt-engine. But I can't run this VM. The message is : 2020-03-26 21:28:02,745+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-147) [] EVENT_ID: USER_FAILED_RUN_VM(54), Failed to run VM VirtMachine due to a failed validation: [Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host xxxxxxxxx did not satisfy internal filter Network because display network ovirtmgmt was missing.] (User: admin@internal-authz). Could you help me ? Thanks Anne
