# 操作环境 #

Openstack icehouse

Centos 6.6x86\_64

# 操作说明 #

修改image文件属性

#glance image-update --property hw_scsi_model=scsi  centos-ceph
    #glance image-update --property hw_disk_bus=scsi  centos-ceph

查看image文件属性

启动新的instance，查看xml文件

硬盘设备，已经显示为sd设备，不在之前的vd设备：

scsi controller设备

进入instance，查看硬盘设备

[root@demo-ceph ~]# fdisk -l /dev/sda
    
    Disk /dev/sda: 21.5 GB, 21474836480 bytes
    255 heads, 63 sectors/track, 2610 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00024449
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1        2611    20970496   83  Linux

查看scsi controller，包含基于virtio-scsi的scsi controller
