Hello. Could someone help to write a config to emulate a VM workload? The goal is to test a storage for VM. Each file on the VM is a disk of a VM. I tried to test the case by the following config: ioengine=posixaio randrepeat=1 norandommap=1 runtime=86400 group_reporting bs=32k time_based=1 iodepth=16 numjobs=1 rw=randrw rwmixread=50 rwmixwrite=50 size=2g [workload] filename=/storage/vm_disk But it seems the above config is not a VM workload. For the second test I created a FS on the file and mounted it. The config was almost the same, except: numjobs=20 size=85m I think the second config is more like a VM workload, than the first. Is it possible to do the same only by FIO?
