Hi, I always encounter this problem.
root@controller:~# nova live-migration --block-migrate instance_test compute2 ERROR: The instance requires a newer hypervisor version than has been provided. (HTTP 400) (Request-ID: req-24bff011-72e0-48b8-9bcb-0f3b82529c0b) I am using Ubuntu Server. And I already applied these configurations. 1. Edit /etc/libvirt/libvirtd.conf listen_tls = 0 listen_tcp = 1 auth_tcp = “none” 1. Edit /etc/default/libvirt-bin libvirtd_opts=" -d -l" 1. Edit /etc/nova/nova.conf, add the line: live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE 1. Restart services. service nova-compute restart stop libvirt-bin && start libvirt-bin *Thanks for the help.*
