Public bug reported: Description ===========
Evacuation takes a long time if the destination host a large number of network interfaces. Steps to reproduce ================== 1. Have a host down, or force it down. 2. Evacuate instances to a host with a large number of network interfaces. Expected result =============== Evacuation completes in a reasonable time frame. Actual result ============= Evacuation takes too long. Additional info =============== This was initially reported against OSP10/Newton [1]. In that case, based on the included sosreports, the compute host has 1324 network interfaces, and 109 instances are being evacuated. That means in total, there's 109 * 1324 = 144316 iterations over the loop in get_machine_ips().
