QEMU后端存储设置之ISCSI前端

本篇是ISCSI服务端的续篇，操作前请确保已经安装好你的iscsi-target

2.1 Install essential software
    sudo apt-get install open-iscsi    

2.2 Modify configuration file
    vim /etc/iscsi/iscsid.conf

and change it to:

    node.session.auth.authmethod = CHAP
    # make sure user and password is same with iscsi-target
    node.session.auth.username =   
    node.session.auth.password =  

2.3 Attach iscsi-target volume
    sudo iscsiadm -m discovery -t sendtargets -p
    sudo iscsiadm -m node --login

other useful command:
    sudo iscsiadm -m node -o show
    sudo iscsiadm -m session -o show

Then, you could find the new patiition:


$ more /proc/partitions    

You could use it as a normal partition, create file system and formation, or provide it to QEMU or Libvirt.

2.4 Logout iscsi partition
    sudo iscsiadm -m node --logout
