"The most significant addition in KubeVirt v1.8 is a Hypervisor Abstraction Layer (HAL) that allows the project to use backends other than KVM, enhancing flexibility for users."
"KubeVirt targets organizations that have adopted Kubernetes but still carry VM-based workloads that cannot easily be rewritten as containers, providing a unified control plane."
"The release also improves Confidential Computing by adding support for Intel TDX Attestation, enabling VMs to cryptographically certify their operation on confidential hardware."
"With the new release, KubeVirt adds PCIe NUMA topology awareness and other resource improvements aimed at AI and HPC workloads, achieving near-native performance."
KubeVirt v1.8 was announced at KubeCon + CloudNativeCon Europe 2026, aligning with Kubernetes v1.35. The release features a Hypervisor Abstraction Layer (HAL) for integrating alternative backends. KubeVirt extends Kubernetes to run traditional VMs alongside containerized workloads, targeting organizations with VM-based workloads. The new HAL allows users to maintain KVM defaults while exploring other virtual machine managers. Additionally, improvements in Confidential Computing support Intel TDX Attestation for secure workloads, and enhancements in PCIe NUMA topology awareness benefit AI and HPC workloads.
