## What this PR does Temporary revert. v1.5.0 restored persistent EFI/TPM state for the `windows.11` / `windows.2k22` / `windows.2k25` profiles. With persistence on, KubeVirt creates a backend-storage PVC (`persistent-state-for-<vm>`) which, on the default `replicated` StorageClass, is **ReadWriteOnce** — it pins the VM to its node and **blocks live-migration and node drains**. With `evictionStrategy: LiveMigrate` this can stall cluster upgrades. See #3005. This strips persistent EFI/TPM from the preferences again — but via `yq del` instead of the original `sed -d`, so an emptied `preferredTPM` stays `{}` (the v1.8 CRD rejects `null`, which is the bug the original strip caused). **Secure Boot and the vTPM remain present, just non-persistent** — Windows VMs still boot; they just don't persist EFI/TPM across reboots. ⚠️ **Temporary stopgap** until vm-state can request an RWX backend — either RWX-Block via the upstream KubeVirt change (kubevirt/kubevirt#18215), or an RWX-Filesystem `vmStateStorageClass`. Once that lands, persistence can be re-enabled with live-migration intact. ### Screenshots No UI changes. ### Release note ```release-note fix(kubevirt-instancetypes): temporarily disable persistent EFI/TPM state to unblock live-migration of Windows VMs. Persistence created a ReadWriteOnce backend-storage PVC on the default storage class, pinning the VM to its node. Secure Boot and vTPM remain available (non-persistent); to be re-enabled once vm-state can use RWX storage. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Updated Windows virtual machine preferences to enable live migration and drain operations * Fixed compatibility issues with KubeVirt v1.8 virtual machine preference configurations * Removed persistent settings from TPM and EFI configurations to prevent blocking behaviors on Windows 11 and Windows Server 2022/2025 variants <!-- end of auto-generated comment: release notes by coderabbit.ai -->
