Description of problem:
Warm migrate vm from vSphere 8 with template settings:
pvcNameTemplate: {{.PlanName}}-{{.VmName}}-{{if eq .DiskIndex .RootDiskIndex}}root{{else}}data{{end}}-{{.DiskIndex}}
networkNameTemplate: {{if eq .NetworkType "pod"}}pod{{else}}multus-{{.NetworkNamespace}}-{{.NetworkName}}-{{.NetworkIndex}}{{end}}
volumeNameTemplate: pvc-{{.PVCName}}-disk-{{.VolumeIndex}}
VirtualMachineCreation phase, hit error:
admission webhook "virtualmachine-validator.kubevirt.io" denied the request: must be no more than 63 characters, must be no more than 63 characters, must be no more than 63 characters, must be no more than 63 characters
Version-Release number of selected component (if applicable):
MTV 2.8.0-29 (IIB: 937321) with CNV 4.18.1
How reproducible:
Always
Steps to Reproduce:
1) Create warm migration plan: mtv-warm-win2022 to migrate vm: mtv-function-win2022-test from vSphere 8 to OCP cluster
2) Set for the templates below and set the Preserve static IPs: on
pvcNameTemplate: {{.PlanName}}-{{.VmName}}-{{if eq .DiskIndex .RootDiskIndex}}root{{else}}data{{end}}-{{.DiskIndex}}
networkNameTemplate: {{if eq .NetworkType "pod"}}pod{{else}}multus-{{.NetworkNamespace}}-{{.NetworkName}}-{{.NetworkIndex}}{{end}}
volumeNameTemplate: pvc-{{.PVCName}}-disk-{{.VolumeIndex}}
3) Start the migration plan, it failed in VirtualMachineCreation phase, hit error:
admission webhook "virtualmachine-validator.kubevirt.io" denied the request: must be no more than 63 characters, must be no more than 63 characters, must be no more than 63 characters, must be no more than 63 characters

mtv-warm-win2022-mtv-function-win2022-test-root-0f99j4 mtv-warm-win2022-mtv-function-win2022-test-data-1nqhmj mtv-warm-win2022-mtv-function-win2022-test-data-22jzxv mtv-warm-win2022-mtv-function-win2022-test-data-3lh8p6
The PVC in VM yaml file will more than 63 characters
pvc-mtv-warm-win2022-mtv-function-win2022-test-root-0f99j4-disk(63 characters)-0random_number
Actual results:
In step3, the migration plan failed to create the VM
