Virtuozzo Hybrid Infrastructure 5.3 Update 1 (5.3.1-38)¶
Issue date: 2022-12-13
Applies to: Virtuozzo Hybrid Infrastructure 5.3
Virtuozzo Advisory ID: VZA-2022-035
This update provides new features for security, monitoring, and the compute service, as well as bug fixes and improvements.
2. New Features¶
[Security] Data-in-transit encryption. To protect networks against eavesdropping attacks and traffic hijacking, Virtuozzo Hybrid Infrastructure supports data-in-transit encryption between cluster nodes. Data transmitted over a network is encrypted by using the AES-128 standard.
[Compute service] Added support for Oracle Linux 7 as a guest operating system.
[Monitoring] Added a set of metrics for monitoring backup storage migration.
[Monitoring] Added metrics and alerts for monitoring backup storage certificates.
3. Bug Fixes¶
It is impossible to start a cluster update after an eligibility check failure. (VSTOR-60452)
A stability fix for Windows 2016/2019 virtual machines on specific CPUs. (VSTOR-60459)
Fixes the false-positive alerts ‘Docker service is down,’ ‘Node is offline,’ and ‘Master metadata service changes too often’ that appear during an update. (VSTOR-60448)
Added dashboards and metrics for the load balancer and Kubernetes API status. (VSTOR-60387)
The Neutron, Cinder, and Nova dashboards may show ‘No data.’ (VSTOR-59696)
Reconfiguration of the compute cluster during an update should be prohibited, to avoid possible issues. (VSTOR-59751)
Fixes autodetection of the image type while uploading images via vinfra. (VSTOR-59617)
If the object storage is deleted, the critical alert ‘Object storage has failed’ should not be raised. (VSTOR-59562)
Fixes the false-positive alert ‘Volume mismatch’ for detached ISO volumes. (VSTOR-59433)
Cannot manage a virtual machine due to temporary snapshot leftovers after live migration. (VSTOR-48706)
An error message is not displayed when a node release from the compute cluster conflicts with another operation. (VSTOR-60304)
Important stability and performance improvements. (VSTOR-51731, VSTOR-59728, VSTOR-59315, VSTOR-54550, VSTOR-56757, VSTOR-59985, VSTOR-60626, VSTOR-60551, VSTOR-60529, VSTOR-60315, VSTOR-60134, VSTOR-59933, VSTOR-59646)
