Hello Vinícius,Do you use OVMF or SeaBios?
If it is OVMF then Lev already nailed the problem.Only WHQL or UEFI
signed drivers will work with secure boot.

I got pretty much mixed results compering WS2008R2 vs WS2012R2 running on RHEL6.5, as well as WS2012R2 running on RHEL6.5 vs WS2012R2 on top of RHEL7.0.

After reading Martijns post I've done some speed test regarding the drive speeds and was looking for a way to compare the VMs on a more professional way. My tests showed, that on the same hardware, the Win2k8 R2 was faster in response and throughput on the disks. I found a utility that somehow measures the latency on a system and that also showed a significant difference. What is the correct way to do a performance test on a VM running in KVM ? Sven Hi Sven, Can you specify the type of disk on your system - ide, virtio-blk, or virtio-scsi? We usually use iometer for disk performance profiling. Sequential read/write, block size from 4K up to 256K, queue depth from 1 to 64.
