-|**5.**| Network connectivity | VM NIC change operation times out after 3 hours, which blocks other VM update operations. On Microsoft Kubernetes clusters, Persistent Volume (PV) dependent pods get stuck. The issue occurs when multiple NICs within a VM are being transferred from a VLAN virtual network to a non-VLAN virtual network. The transfer involves asynchronous calls that are processed in the same thread. If one NIC transfer is made while the other NIC transfer is still processing, a deadlock could occur due to the shared API activity ID in one thread. To mitigate this issue, the API activity ID would be uniquely generated even within one thread, ensuring that the parallel calls are independent and don't affect each other. After the fix, the VM NIC change operation times out quickly and the VM update won't be blocked. |
