The new proxmox ve 6.4 is based on debian gnu / linux 10.9 "bustler" with a linux kernel 5.4 (lts) or optional 5.11. Overview of webgui, the ha-maleval virtualization solution manages both virtual machines as well as linux containers.
The virtual machines provide a combination of qemu 5.2 with kvm available, with vms per "pinning" bind to certain qemu machine versions. Linux container, provided by lxc 4.0, allow improved cgroup v2 handling. Prefabricated application templates are available for alpine linux 3.13, fedora 34, ubuntu 21.04 and that from systemd released devuan 3 "beowulf".
The two ceph variants selectable during the installation and distributed proxmox clusters were added to 15.2.11 (ceph octopus, before 15.2.6) and 14.2.20 (ceph nautilus, before 14.2.15) updated. The integration of the placement group (pg) auto-scaler has been improved.
Vms and containers, mail and backups
One month ago, the developers already publately published the mail gateway 6.4. The mail proxy works between firewall and mail server and offers extensive spam and virus protection. An object-oriented rules defines filter rules according to usernames, domains, timeframe, type of content and the resulting action. Proxmox ve 6.4 and proxmox mail gateway 6.4 work seamlessly with proxmox backup server 1.1 together.
With proxmox ve 6.4 there is one "unified single-file restore" for vms and containers whose backups on the backup server 1.1. Individual files or directories can be restored as convenient via the webgui. With liverestore, proxmox is starting the vm already during the restore process, which according to the manufacturer mainly at vms with small core system but rough data areas is helpful.
Switch to openzfs 2.0
With the update just openzfs 2.0.4 feed and lost the previous zfs 0.8th.5 off. Openzfs 2.0 leads the previous three development branches of freebsd, gnu / linux and illumos. As with upgrades from freebsd 12.2 on freebsd 13, the transition from the respective system-specific zfs implementations to the common openzfs basis does not always go smoothly. In particular, pool upgrades should use users with consideration. Many improvements, especially in the arc and l2arc caches and compression with the zstard (zstd) developed on facebook, weigh any complications.
Vienna proxmox server solutions gmbh documents all innovations and planned developments in a roadmap. Proxmox ve 6.4 is available now and is under the gnu affero gpl v3. The open source software can be used free of charge without access to the enterprise repository, professional support including the latter cost 90 (previously 85) to 840 euros (net) per year and cpu socket.
