The main docs we have are


They are basically more reference guides that howto/tutorials. Also
look at the 'virsh help' output for 'vol-XXX' and 'pool-XXX' commands.

As a simple example...

  - Create an XML definition for the iSCSI target you want to access,

      # cat > virt.xml <<EOF
      <pool type="iscsi">
          <host name="iscsi.example.com"/>
          <device path="demo-target"/>

  - Define the pool

     # virsh pool-define virt.xml

  - Activate the pool (this step logs into the server)

     # virsh pool-start virtimages

  - List the LUNs available

     # virsh vol-list virtimages

  - Query info about a LUN

     # virsh vol-info --pool virtimages  lun-3
     # virsh vol-dumpxml --pool virtimages  lun-3

There's many more pool-XXX and vol-XX commands available
