Folks, I am running openstack queens and hypervisor is kvm, my live migration working fine. but somehow it stuck to 8 Mb network speed and taking long time to migrate 1G instance. I have 10Gbps network and i have tried to copy 10G file between two compute node and it did copy in 2 minute, so i am not seeing any network issue also.
it seem live_migration has some bandwidth limit, I have tried following option in nova.conf but it didn't work live_migration_bandwidth = 500 My nova.conf look like following: live_migration_uri = "qemu+ssh://nova@%s/system?no_verify=1&keyfile=/var/lib/nova/.ssh/id_rsa" live_migration_tunnelled = True live_migration_bandwidth = 500 hw_disk_discard = unmap disk_cachemodes = network=writeback _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
