Manage Shared Block Device (RWX Block) for KubeVirt VMs

The Portworx RWX block volume is designed and qualified only for use with the KubeVirt VM use case. It isn't intended for use as a generic ReadWriteMany (RWX) block volume type in other scenarios. Contact support to confirm suitability for other use cases (outside of the KubeVirt VM) before deployment.

KubeVirt is an extension for Kubernetes that offers the flexibility to manage traditional VM-based workloads alongside modern containerized applications within a Kubernetes framework.

Portworx supports volumes for virtual machines (VMs) as storage disks in various configurations. To enable features such as live migration, these volumes must support the ReadWriteMany (RWX) access mode. Portworx supports the RWX block volume type, which offers improved performance in certain scenarios, and also supports the RWX file system (FS) volume type.

Portworx does not support the following configurations with shared raw block for KubeVirt VMs:

  • Synchronous disaster recovery
  • Asynchronous disaster recovery for virtual machines (VMs) on Portworx raw block volumes that were migrated from another environment, such as VMware
