Create an iSCSI storage pool

Import lib1_conn = libvirt. open ('qemu: // system') # conn = libvirt. open ('qemu: // system ') /dev/Disk/by-pathxmldesc = ''' <pool type = 'iscsi '> <Name> iSCSI </Name> <source>  
 
Logical concept correspondence:
 
When a storage pool is created and an iqn In The iSCSI server is used as the device, the iqn can understand a pool, and the Lun in the iqn corresponds to the volume in libvirt, if multiple iqn storage pools are created, the storage pool concept should correspond to the iSCSI server more accurately, and the volume should correspond to the Lun.
