Proxmox team launched the latest version of its virtualization management platform Proxmox VE 6.2. It’s built on Debian Buster 10.4 and a 5.4 longterm Linux kernel, QEMU 5.0, LXC 4.0, ZFS 0.8.3, Ceph 14.2.9 (Nautilus), and ZFS 0.8.3. Proxmox VE 6.2 brings a built-in validation of domains for Let’s Encrypt TLS certificates via the DNS-based challenge mechanism. It also offers full support for up to eight corosync network links, support for Zstandard for Backup/Restore, and a new LDAP sync for users and groups and full support for API tokens. The ISO file can be downloaded here.
