[Qemu-devel] [PATCH 6/9] vhost-scsi: new device supporting the tcm_vhost Linux kernel module

[Libaiqing]

Hi asias,
   I'm testing vhost-blk,for comparimg the performance with virtio-blk.
   I got the kernel patch from this mail: https://lkml.org/lkml/2012/12/1/174
   And I got the userspace code for qemu from this git: 
https://github.com/asias/qemu/tree/blk.vhost-blk;
   Used vhost-blk device as non-bootable device,the configuration is :   
        Qemu-kvm -enable-kvm -name win7 -M pc-0.15 -m 1024 -smp 2 -boot c 
-device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive 
file=/home/fedora188.img,if=virtio,index=0,format=raw  -drive 
file=/home/fedora18.img,if=virtio,index=1,format=raw,id=hd,vhost=on   -monitor 
stdio   -vga qxl  -vnc :1  -device usb-tablet,id=input0

   On fedora17 host,I used kernel 3.6.3 for building vhos_blk module,but the vm 
will hang when vm starting.

   1 Is there any new patch for kernel 3.8 3.10?
   2 which version of the kernel is suitable for the current kernel patch?

   Could you give me some advise to debug this problem ? I can provide more 
information if need.
   Or could you give me some advise to run vhost-blk,such as RHEL 
version,kernel version and so on?

Thanks
Baiqing.
