Hello, Nicolas,

I have not found a solution. 

The problem ist SATA-controllers own BIOS and his initialization in XEN-gue= st. So I refuse from Sata-controller.

XEN had bad disk performance in guest. I tried KVM with guest-image-file on= SSD (mounted in Host system and through mainboard controller), here was be= st disk performance. But I needed graphic card in guest and I could not ins= tall the graphics card driver in KVM.
As You know XEN, as KVM  based on Qemu. So I tried Qemu. This solution= I have left me.

Following I attach my CrystalDiskMark tests.
