Report InstanceID for vSphere Cloud Provider as UUID obtained from product_serial file **What this PR does / why we need it**: vSphere Cloud Provider is not able to find the nodes for VMs created on vSphere v1.6.5. Kubelet fetches SystemUUID from file ```/sys/class/dmi/id/product_uuid```. vSphere Cloud Provider uses this uuid as VM identifier to get node information from vCenter. vCenter v1.6.5 doesn't recognize this uuids, as a result, nodes are not found. UUID present in file ```/sys/class/dmi/id/product_serial``` is recognized by vCenter. Yet, Kubelet doesn't report this. Therefore, in this PR InstanceID is reported as UUID which is fetched from file ```/sys/class/dmi/id/product_serial```. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes https://github.com/kubernetes/kubernetes/issues/58927 **Special notes for your reviewer**: Internally review here: https://github.com/vmware/kubernetes/pull/452 Tested: Launched K8s cluster using kubeadm (Used Ubuntu VM compatible with vSphere version 6.5.) _**Note: Installed Ubuntu from ISO**_ Observed following: ``` Master > cat /sys/class/dmi/id/product_uuid 743F0E42-84EA-A2F9-7736-6106BB5DBF6B > cat /sys/class/dmi/id/product_serial VMware-42 0e 3f 74 ea 84 f9 a2-77 36 61 06 bb 5d bf 6b Node > cat /sys/class/dmi/id/product_uuid 956E0E42-CC9D-3D89-9757-F27CEB539B76 > cat /sys/class/dmi/id/product_serial VMware-42 0e 6e 95 9d cc 89 3d-97 57 f2 7c eb 53 9b 76 ``` With this fix controller manager was able to find the nodes. **controller manager logs** ``` {"log":"I0205 22:43:00.106416 1 nodemanager.go:183] Found node ubuntu-node as vm=VirtualMachine:vm-95 in vc=10.161.120.115 and datacenter=vcqaDC\n","stream":"stderr","time":"2018-02-05T22:43:00.421010375Z"} ``` **Release note**: ```release-note vSphere Cloud Provider supports VMs provisioned on vSphere v1.6.5 ```
