KubeVirt VirtualMachineInstanceMigration spec.vmiName field identifies the VMI documentation
💡 Result:
In KubeVirt, the spec.vmiName field within a VirtualMachineInstanceMigration (VMIM) resource is a required string field that specifies the name of the VirtualMachineInstance (VMI) to be migrated [1]. This field acts as the primary identifier used by the KubeVirt controller to associate the migration request with the correct running virtual machine instance [2]. By creating a VirtualMachineInstanceMigration object and setting spec.vmiName to the name of the target VMI, a cluster administrator or user initiates the live migration process [3][4][5]. Key characteristics include: - Purpose: It identifies the specific VMI instance that is intended to be moved from its current node to a new target node [1]. - Requirement: It is a required field under the spec object of the VirtualMachineInstanceMigration resource [1]. - Usage: It is used in both standard live migration workflows [3][5] and more advanced configurations such as decentralized live migration [6]. For official technical specifications, you can refer to the KubeVirt OpenAPI documentation [1] or the KubeVirt User Guide on Live Migration [3].

Make the stuck-sync check VM-aware.
VmimPhase reads .items[0].status.phase from the namespace-wide VMIM list. When vmCount > 1, this can return another VM’s phase. Select the VMIM by spec.vmiName or its owning VM label.
The loop returns after the first VM with Synchronization == Running, so later VMs are not checked. Use per-VM timers and reset each timer when its VM leaves Running.
DumpDiagnostics writes the full namespace VMIM list to every per-VM file. Filter each list by VM or write one namespace-level VMIM file.

KubeVirt masquerade binding connect to VM IP from virt-launcher compute container
💡 Result:
In KubeVirt's masquerade binding mode, virtual machines (VMs) are connected to the pod network through a Linux bridge and Network Address Translation (NAT) managed within the virt-launcher pod [1][2][3]. Because this mode hides the VM behind the pod's IP address, accessing the VM directly from the virt-launcher container or other cluster workloads requires specific configuration [4][5]. Key Mechanisms and Connectivity: 1. NAT and Pod Network: When masquerade mode is used, KubeVirt configures the virt-launcher pod to act as a NAT gateway for the VM [1][2]. The VM receives an internal IP address (e.g., in the 10.0.2.0/24 range by default) assigned via an internal DHCP server running inside the pod [1][2][5]. Outgoing traffic from the VM is source-NAT'd to the pod's IP address [4][5]. 2. Connecting to the VM: To access the VM from outside the virt-launcher pod (i.e., from other cluster workloads or the external network), you should target the pod's IP address or use a Kubernetes Service [4][5]. Since the VM is hidden behind the pod's network namespace, you must configure port forwarding in the VM definition to allow traffic to reach specific ports inside the guest [4][3]. 3. Configuring Ports: If you need to access specific services running in the VM (e.g., SSH on port 22 or HTTP on port 80), you must explicitly add these to the ports section of the interface configuration in your VirtualMachine manifest [4][6]: spec: template: spec: domain: devices: interfaces: - name: default masquerade: {} ports: - port: 80 - port: 22 4. Limitations on "Self" Access: A known limitation is that a VM in masquerade mode generally cannot access itself by reaching out to the pod's IP address [7]. This is because the traffic path is designed for external-to-VM or VM-to-external communication, and self-referential NAT loops are typically not supported or intended [7]. If a guest needs to reach its own services, it should be configured to resolve to its loopback address (127.0.0.1) [7]. For general connectivity, ensure that the virt-launcher pod is running correctly and that no local host or guest firewalls are blocking the traffic you are attempting to route [8][6]. Connectivity to the VM from outside the cluster is best managed by creating a Kubernetes Service that selects the virt-launcher pod using the appropriate labels (e.g., kubevirt.io/domain) [4][5].

site:github.com/kubevirt/kubevirt masquerade virt-launcher connect to own VM IP hairpin NAT
💡 Result:
When using KubeVirt masquerade binding, a Virtual Machine (VM) running inside a virt-launcher pod cannot connect to its own pod IP or external ClusterIP because of how the underlying NAT rules are structured [1]. In this networking mode, the virt-launcher pod creates a virtual gateway to the VM, and all traffic is SNAT'd/DNAT'd through this gateway [2]. This architecture does not inherently support "hairpin" connectivity where the VM attempts to communicate with its own external-facing pod IP address [1]. Key Technical Details: - The masquerade binding mechanism works by setting up an in-pod bridge (often associated with an interface like k6t-eth0) and using nftables (formerly iptables) to route traffic [2][3][4]. - When a VM attempts to connect to its own pod IP, the packets are often dropped or ignored because the NAT rules are primarily designed for ingress/egress communication between the VM and external entities, rather than loopback-style communication to the pod's primary IP [1]. - Official recommendations and community workarounds include resolving the address at the guest level to localhost (127.0.0.1) instead of the pod IP [1]. - For advanced use cases, some users have experimented with manual nftables rule injections to reverse the source and destination of these packets, though this is considered an edge case and is difficult to maintain [1]. - If you require specific port access or more complex networking behavior, consider newer binding mechanisms such as passt, which may offer different connectivity characteristics [5]. In summary, the inability to connect to the VM's own pod IP is a known limitation of the masquerade binding design [1]. For most applications, the best practice is to configure the guest OS to treat its own services as running on localhost [1]. If this is not feasible, creating a custom network binding plugin or utilizing newer binding types like passt is the recommended path forward [1][5].

Skip the SSH probe when vmCount == 1. The current index selects the same virt-launcher pod, so the default configuration performs a self-probe instead of a cross-VM probe. This can record a misleading JUnit failure while || true keeps the step green.

Restrict the unverified path to valid release-X.Y tags.
Every value that does not start with v and a digit enters the rolling-tag branch. Empty and malformed values then skip checksum verification and can reach extraction without a trusted digest. Reject values unless they match a full immutable vX.Y.Z pattern or a full rolling release-X.Y pattern.
