comment Very high I/O wait time on KVM virtual machine
Guys, it does use VirtIo emulation already, since first start. It never used sata emulation. I posted a screenshot there from virt-manager, where you can see hdd settings of that virtual machine.

comment Very high I/O wait time on KVM virtual machine
I was checking md1 with cat /proc/mdstat and with some command like echo check > /sys/block/md1/md/sync_action, it does once every month and no disk was removed from array.

HDD size is 24GB, 11G free, used is 54% of filesystem. It works on ext4. No LVM at the virtual machine. Disk cache mode is same as on different virtual machines. Virtio, format qcow2, mode cache : default, io mode: default. Running on debian wheezy, host machine also debian wheezy.
