The libvirtd service can respond with significant delays.
CloudBoot compute resources
1. Speed up migration by adding the following entry to custom config (/etc/hosts) on all of your CloudBoot compute resources:
# echo -e $(ip -4 addr show dev mgt scope global | awk '$1 ~ /inet/
')'\t'$(hostname) >> /etc/hosts
2. Restart libvirtd service:
# systemctl restart libvirtd
Delays in libvirtd service response may appear when the hostname of a CloudBoot compute resource is not resolvable.
