Recently our hospital went online KVM virtualization, distributed storage with Openvstorage, found on the above running LIS business ioPS is very low, Lis is mainly to store and read some small files, how to optimize can improve its IOPS reading and writing performance! We had to migrate the VM to the local disk, which is normal on the local disk.

Can you share some more details of your setup? Which version are you running? How is KVM configured to access the volumes (files in the fuse mountpoint or using the OVS qemu plugin)?
