Glance INSTALL
 glance-api : 이미지검색, 저장등을 위해 이미지 API 호출을 받아들인다.
 glance-registry : 이미지에 대해 메타데이터를 받아 처리, 저장하며 메타데이터는 크기와 종류등의 항목을 포함합니다.

설치이후 glance 저장소 이미지를 관리하는데... qemu 명령어가 필요한경우가 있으니 필요에 따라서 아래 패키지도 설치
root@controller:~# apt-get -y install qemu-kvm kpartx

glance 데이타베이스 및 유저생성
root@controller:~# mysql -u root -pXXXXXXXXXXXXXXX
mysql> CREATE DATABASE glance;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'XXXXXXXXXXXXXXX';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'XXXXXXXXXXXXXXX';
Query OK, 0 rows affected (0.00 sec)

mysql> exit

이미지등록
OpenStack 메뉴얼상에서는 가장이미지 싸이즈가 적은 CIrros 이미지로 등록되는 방법으로 명시되어있습니다.
Cirros 는 클라우드서비스내에서 실행을 전문적으로 적은 용량에 OS 입니다.
