Virtualization: Containers and VMs with Proxmox VE 7.0

table of contents

Proxmox is unquestionably popular – but how do the Viennese manage to compete against virtualization heavyweights such as VMware, Microsoft and Red Hat? The regular and reliable updates – after all, the new Virtual Environment (VE) 7.0 appeared just two months after version 6.4 – are only part of the answer. Rather, the attractiveness of the package is to be sought in its flexibility.

Proxmox Virtual Environment, Proxmox VE for short, is a cluster and HA (high availability) platform for the simultaneous provision of kernel-based VMs via KVM / QEMU and containers via LXC. The entire administration – even entire clusters – takes place via a central web interface or the command line. The new version 7.0 offers all storage options that are also available under Debian GNU / Linux. LVM groups, ZFS pools or simple directories on any file system can be used locally, iSCSI targets or LUNs, CIFS / SMB or NFS shares, but also GlusterFS or Ceph can be used in the network. All virtual machines and containers can be created and used on local and network-based storage devices.

If the images of the virtual machines are in the network, virtual machines can be migrated live, i.e. with almost no downtime, within the cluster. A local migration also works live, local ZFS accelerates this even more. The internal DRDB storage plug-in was removed in version 7.0 because it is out of date – the manufacturer Linbit offers its own Linstor implementation directly. There are many small improvements in the storage area of ​​the web GUI, such as the option to completely delete drives or ISO- und Appliance-Images directly via the admin workstation from a URL to the storage system.
