Why VM live migration is failing with error "netplugin failed: /var/lib/cni/bin/cnv-bridge: /lib64/libc.so.6: version `GLIBC_2.32' not found"?

Issue

• The VM live migration was failing when the worker pool was upgraded during the EUS upgrade from 4.12 to 4.14. Destination virt launcher pod fails to start and logged below message:
