I can confirm the parallelism, as I tried with 2 VMS, both with 3 disks: 20Gb+20Gb+90Gb the first VM1 and 20Gb+20Gb+80Gb the second one VM2. The source storage domain is based on iSCSI Equallogic with 10Gbit/s connection. The export domain is a vSphere VM (on 10Gb/s adapter) connected through the ovirtmgmt channel (that is based on 10Gb/s adapters in LACP) Going one by one I got Starting export Vm VM1 to xfer 11/4/21 12:14:49 PM Vm VM1 was exported successfully to xfer 11/4/21 12:21:54 PM --> total 7' 5" Starting export Vm VM2 to xfer 11/4/21 12:25:23 PM Vm VM2 was exported successfully to xfer 11/4/21 12:32:19 PM --> total 6' 56" Going then in parallel (delay of 7 seconds, not using the method of multi-select and export): Starting export Vm VM1 to xfer 11/4/21 3:15:29 PM Starting export Vm VM2 to xfer 11/4/21 3:15:36 PM Vm VM2 was exported successfully to xfer 11/4/21 3:26:32 PM Vm VM1 was exported successfully to xfer 11/4/21 3:26:46 PM ---> total 11' 17" So I got about a 20% gain. Next week I have to move some VMs with 900Gb of storage each, so I can get optimizations going in parallel Thanks, Gianluca
