I am using proxmox beta 4 in my HP DL 380 server with KVM. I configured Intel P3700 NVME - nvme0n1 as Virtio and on windows server 2008 r2 with virtio-scsi driver.
I am getting 100 K random IOPS when iothread is enabled.it works fine. (the max capacity of the drive is 460 K , and in win2k8 bare metal it gets 350 K random iops!).
But I learned that "vhost-scsi" makes 200k IOPS and lower latency. I am making the disk "SCSI" and "scsi controller" = "Virtio Scsi" , it works in the win2k8 guest as Redhat Virtio SCSI Passthrough, but it only gets 78k IOPS and cpu is overloaded.
I enabled CONFIG_VHOST_SCSI=m in vpe kernel config, but I don't know it is enough to do this.
How can I use vhost-scsi in proxmox? How to enable, how to setup the disks, which drivers to use etc?
