Description of problem:
live migrating more then 45 VM from 2 nodes(each with 22-27 vms) generates below error
Error migrating VirtualMachine Internal error occurred: Internal error occurred: failed calling webhook "migration-create-validator.kubevirt.io": failed to call webhook: Post "https://virt-api.openshift-cnv.svc:443/migration-validate-create?timeout=10s": context deadline exceeded
Version-Release number of selected component (if applicable):
openshift-cnv kubevirt-hyperconverged-operator.v4.18.8 OpenShift Virtualization 4.18.8 kubevirt-hyperconverged-operator.v4.18.3 Succeeded openshift-ovirt-infra node-healthcheck-operator.v0.9.0 Node Health Check Operator 0.9.0 node-healthcheck-operator.v0.8.2 Succeeded
How reproducible:
virtctl migrate "$vm_name" -n "$NAMESPACE"and pass in list of 45 vm names from 2 nodes
Steps to Reproduce:
1.migrate 45 or more vms from 2 nodes
2.for ((i=0; i<COUNT && i<${#all_vms[@]}; i++)); do
vm="${all_vms[$i]}"
migrate_vm "$vm" & # virtctl migrate "$vm_name" -n "$NAMESPACE" done
to migrate vm in parallel
3.Got below error Error migrating VirtualMachine Internal error occurred: Internal error occurred: failed calling webhook "migration-create-validator.kubevirt.io": failed to call webhook: Post "https://virt-api.openshift-cnv.svc:443/migration-validate-create?timeout=10s": context deadline exceeded
Actual results:
