Virtuozzo Hybrid Infrastructure 6.1 (6.1.0-238)

Issue date: 2024-03-28

Applies to: Virtuozzo Hybrid Infrastructure 6.1

Virtuozzo Advisory ID: VZA-2024-013

1. Overview

In this release, Virtuozzo Hybrid Infrastructure introduces a new service—Backup and Restore as a Service—as well as provides a range of new features that cover improvements in the compute services and object storage. Additionally, this release delivers stability and security improvements, and addresses issues found in previous releases.

2. New Features

  • [Compute service] Integrated Backup and Restore as a Service. The new backup service allows you to back up VM volumes, and then restore virtual machines and volumes from them. This helps to prevent data loss and mitigate issues with software or hardware. The service supports external and integrated storage (NFS and Object Storage) as a backup destination, thus eliminating the need for purchasing an external backup solution and decreasing the product TCO.

  • [Compute service] New features for load balancers. Added support for the HTTP headers, PROXY protocol, TLS, and certificate upload for the load balancing service.

  • [Compute service] External iSCSI storage support. Starting from this release, the compute service supports any external iSCSI storage system that has the OpenStack Cinder driver. You can find the list of available iSCSI drivers at

  • [Compute service] Support for new Kubernetes versions: 1.26, 1.27, 1.28. Starting from this release, the Kubernetes release support policy will be the following:

    • We support only the four latest minor versions. For example: 1.28, 1.27, 1.26, and 1.25.

    • We support only the latest patch for the supported minor version.

    • We provide support for a new minor version during a six-month period after the upstream release.

  • [Compute service] Baseline CPU model per node. To combine multiple generations of the same CPU vendor, you need to set the baseline CPU model based on the oldest generation, to make all CPUs compatible with each other. Previously available only for the entire compute cluster, the baseline CPU model now can be set on the per-node basis. Thus, you can have multiple sets of CPU generations in a single cluster covered by multiple CPU models.

  • [Compute service] Improved domain quota management. Now, you can set domain quotas for vCPUs, RAM, and storage policy space in the admin panel.

  • [Compute service] Improved monitoring for virtual machines. The new monitoring charts available in the admin and self-service panels show separate metrics for each VM volume and network interface.

  • [Compute service] SSL protocol support for Kafka connection. Added the possibility to configure the SSL protocol for Kafka connection, to secure message transfer between your cluster and metering solution. SSL can be configured for encryption and also serves as two-way authentication between the Kafka server and client.

  • [Compute service] New guest OS support. Added support for SUSE Linux Enterprise 15 (SP3, SP4, SP5) as a guest operating system.

  • [Object storage] Performance improvements. Added the possibility to place NS and OS journals on a faster storage tier than is used for data, to improve S3 storage performance.
