Proxmox VE is an open source server virtualization environment, based on Debian, with a modified version of the Ubuntu LTS Kernel.
It was unveiled on lRelease of the new version of Proxmox Virtual Environment 7.3, version in which a large number of changes have been implemented, of which template updates, support improvements, bug fixes and more stand out.
For those who are unaware of Proxmox VE, they should know that this distribution provides the means to implement an industrial grade virtual server system with web-based management, designed to manage hundreds or even thousands of virtual machines.
Among the features of the web interface: support for a secure VNC console; role-based access control to all available objects (VM, storage, nodes, etc.); support for various authentication mechanisms (MS ADS, LDAP, Linux PAM, Proxmox VE authentication).
Main new features of Proxmox Virtual Environment 7.3
This new version of Proxmox VE 7.3 arrives synchronized with the Debian 11.5 base packages. By default, the Linux kernel 5.15.74 is proposed, but the user is also offered the possibility of being able to upgrade directly to version 5.19 optionally.
Another of the changes that stands out in the new version is that the ability to connect hot-plugged USB devices to virtual machines, In addition to being added support for forwarding up to 14 USB devices to a virtual machine. By default, virtual machines use the qemu-xhci USB driver. Improved handling of forwarding PCIe devices to virtual machines.
In addition to this, it is also noted that the sInitial support for Cluster Resource Scheduling (CRS), which searches for new nodes required for high availability and uses the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) to select the most optimal candidates, taking into account memory and vCPU requirements.
We can also find that the utility proxmox-offline-mirror has been implemented to create local mirrors from the Proxmox and Debian package repositories, which can be used to update systems on an internal network that does not have access to the Internet, or completely isolated systems (by mirroring a USB drive).
La web interface now has the ability to bind tags to guest systems to simplify their search and grouping. Improved interface for viewing certificates.
Were added new container templates for AlmaLinux 9, Alpine 3.16, Centos 9 Stream, Fedora 36, Fedora 37, OpenSUSE 15.4, Rocky Linux 9, and Ubuntu 22.10, as well as updated templates for Gentoo and ArchLinux.
Of the other changes that stand out:
- Provided the ability to add a local storage (zpool with the same name) to multiple nodes. Improved display of complex formats in api-viewer.
- ZFS supports dRAID (Distributed Spare RAID) technology.
- Updated QEMU 7.1, LXC 5.0.0, ZFS 2.1.6, Ceph 17.2.5 (“Quincy”), and Ceph 16.2.10 (“Pacific”).
- Simplified binding of processor cores to virtual machines (using task set).
- The Proxmox Mobile app has been updated to use the Flutter 3.0 framework and is compatible with Android 13.
- New major version of LXC 5.0.0
More robust cgroup mode detection, by explicitly checking the type of /sys/fs/cgroup - Binding mounts are now also applied directly to a running container
- Fixed bug when cloning a locked container: no longer creates an empty configuration, but fails correctly
- Improvements to systemd version detection inside containers
- Volumes are now always deactivated when successful
move_volume, not only if the source volume is to be deleted: dangling krbd allocations are prevented. - Improvements to the naming of WebAuthn parameters in the GUI.
- Increase OpenID code size: Support for Azure AD as an OpenID provider.
- Support for newer distribution versions:
- Fedora 37 and preparation for 38
- They return 12 Daedalus
- Preparation for Ubuntu 23.04
