Boost your cloud performance with Atmosphere's latest releases: v1.13.11 for OpenStack Zed, v2.2.11 for Antelope, v3.2.12 for Bobcat, and v4.2.12 for Caracal. These updates bring seamless operations, improved resource management, and fortified security to your cloud environment.
Ensuring that the cloud infrastructure benefits from the latest software developments and optimizations is a top priority for VEXXHOST, reflecting our commitment to the ongoing enhancement and reliability of Atmosphere cloud services. In line with this, we have crafted four new releases that introduce improvements and fixes to keep services running smoothly and efficiently for all users.
We proudly introduce Atmosphere v1.13.11 for OpenStack Zed, v2.2.11 for Antelope, v3.2.12 for Bobcat, and v4.2.12 for Caracal.
This blog post takes a closer look at the tangible improvements in these releases, which bring a suite of new features, upgrades, and bug fixes to enhance the functionality and stability of the cloud infrastructure.
The integration of liveness probes for the ovn-northd service represents a significant reliability enhancement in all these latest releases. By implementing these probes, Atmosphere can now automatically detect and restart any ovn-northd processes that become unresponsive, thereby maintaining the integrity of the virtual network configuration and ensuring uninterrupted network policy enforcement. This proactive monitoring and self-healing capability is a testament to our commitment to delivering a robust and dependable cloud platform.
New features
- Liveness Probes for
OVN-Northd
The ovn-northd service, critical for managing the virtual network's high-level configuration, now has liveness probes enabled by default. This ensures any process that is not responding correctly will be automatically restarted, thus enhancing the reliability of the network management. - Neutron's Enhanced DHCP Support
Neutron, the networking component of OpenStack, now supports the use of the built-in DHCP agent in conjunction with OVN. This is especially important for configurations that require a DHCP relay, further extending Neutron's versatility.
Bug Fixes
- Privileged Operations Configuration
Previously, the [privsep_osbrick]/helper_command configuration was not set in the Cinder and Nova services, leading to the incorrect execution of some CLI commands using plain sudo. This issue has been rectified by adding the necessary helper command configuration to both services. Dmidecode Package Inclusion
The dmidecode package, essential for certain storage operations, was previously missing from some images. Its inclusion now prevents NVMe-oF discovery problems, ensuring smoother storage management. This dependency has now been addressed by including the package in all relevant images. Nova-SSH Image Configuration
The nova-ssh image was missing a critical SHELL build argument for the nova user, causing migration failures. With the argument now added, live and cold migrations should proceed without issues.- Kernel Option for Asynchronous I/O
A new kernel option has been introduced to handle a higher volume of asynchronous I/O events, which prevents VM startup failures due to reaching AIO limits. - Magnum Cluster API Driver Update
The Cluster API driver for Magnum has been updated to use internal endpoints by default. This adjustment avoids the need for ingress routing and takes advantage of client-side load balancing, streamlining the operation of the service.
Upgrade Notes
Available for Atmosphere v2.2.11, v3.2.12 & v4.2.12.
- OVN Upgrade
The OVN version has been upgraded from 24.03.1-44 to a more recent version, which includes important improvements and bug fixes that enhance network virtualization capabilities and overall infrastructure performance.
These updates work towards a more reliable and efficient cloud infrastructure, reducing potential downtimes and improving the overall user experience.
With each new version, we roll out enhancements that refine performance, streamline operations, and shore up security, ensuring your infrastructure is not just keeping up, but setting the pace.
As usual, we encourage our users to follow the progress of Atmosphere to leverage the full potential of these updates.
