A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.", "title": "Topic" }, { "category": "general", "text": "ovirt-ansible-repositories is an Ansible role used to set up the repositories required for oVirt engine or host installation.\n\nThe openvswitch package contains components for enabling Open vSwitch; a software-based Ethernet virtual switch. It also includes OVN (Open Virtual Network) components for supporting virtual network abstraction.\t\n\nThe Red Hat Virtualization Python SDK is a program that simplifies access to the Red Hat Virtualization API by providing an object-oriented view to developers.\n\nSecurity Fix(es):\n\n* dpdk: librte_vhost Interger overflow in vhost_user_set_log_base() (CVE-2020-10722)\n\n* dpdk: librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair() (CVE-2020-10723)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n\nBug Fix(es):\n\n* Previously, during RHHI-V deployment of 3 hosts using ovirt-ansible-hosted-engine-setup, the Self-Hosted Engine was added to the default cluster, but the additional 2 hosts were not added.\nIn this release, deployment with ovirt-ansible-hosted-engine-setup successfully adds all hosts to the cluster. (BZ#1855283)\n\n* Previously, when creating large numbers of virtual machines (~2300 VMs), the associated Data Centers became unresponsive, and the hosts did not have Storage Pool Managers (SPM).\nWith this release, large scale deployment of virtual machines succeeds without errors.
