一.为其他组分配instances：
1.进入192.168.77.51
2.如下操作：
查看images：
euca-describe-images
查看类型；
sudo nova-manage flavor list
选择类型并启动instances：
euca-run-instances ami-00000014 -t m1.hcType
获取地址：
euca-allocate-address
分配地址：
euca-associate-address -i i-000000c8 192.168.77.241
查看instance：
euca-describe-instances | grep 192.168.77.241
进入所在computer，查看VNC端口
ps -ef|grep instances | grep c8
VNC进入，修改防火墙和远程链接，重启instances：
euca-reboot-instances i-000000c8
------------------------------------------------
上传模板：
glance add name="foranybackup" is_public=true < /home/testcloud/win-2003-x86_64.img --host=192.168.77.109
------------------------------------------------
卷相关：
sudo pvs
sudo vgs
sudo lvs
euca-describe-volumes
euca-attach-volume -i i-00000081 -d /dev/vdc vol-00000017
------------------------------------------------
自定义instance类型：
sudo nova-manage flavor create --name=m1.Hao500G --memory=8192 --cpu=8 --local_gb=500 --flavor=16 --swap=0 --rxtx_quota=0 --rxtx_cap=0
sudo nova-manage flavor create --name=m1.hcXCF --memory=4096 --cpu=2 --local_gb=50 --flavor=20 --swap=0 --rxtx_quota=0 --rxtx_cap=0
------------------------------------------------
直接使用img启动虚拟机：
创建镜像：sudo kvm-img create -f qcow2 RHEL6_x86_64.img 20G
sudo kvm -m 2048 -cdrom rhel-server-6.0-x86_64-dvd.iso -drive file=RHEL6_x86_64.img,if=virtio,index=0,boot=on -boot d -net nic -net user -nographic -vnc :25
sudo kvm -m 2048 -drive file=***.img -boot c -usbdevice tablet -nographic -vnc :*
------------------------------------------------
指定compute节点所在机器
nova-manange service disable dev-compute* nova-compute
------------------------------------------------
多节点出现问题时候解决办法：(重装nova-computer服务)
sudo apt-get autoremove nova-compute
sudo apt-get install -y nova-compute
virsh list
sudo service nova-compute restart
sudo service nova-compute start
sudo service nova-compute restart
virsh list
sudo apt-get autoremove nova-compute
sudo apt-get install -y nova-compute
euca-describe-availability-zones verbose
virsh list
----------------------------------------------
sudo kvm -m 2048 -drive file=win-2003-x86_64.img -boot c -usbdevice tablet -nographic -vnc :65
euca-attach-volume -i i-000000f0 -d /dev/vdc vol-00000025
----------------------------------------------
配置网桥
brctl addbr br0
brctl addif br0 eth0
增加网桥：
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig eth0 0.0.0.0 promisc
ifconfig eth1 0.0.0.0 promisc
brctl addif br0 eth0 eth1
brctl show
ifconfig br0 10.10.1.1 netmask 255.255.0.0 up
删除网桥接口：
brctl delif br0 eth0 eth1
删除网桥：
brctl delbr br0
关闭生成树：
brctl stp br0 off
----------------------------------------------
1、创建网桥设备 br0： brctl addbr br0
2、向br0中添加网卡 eth0 eth1
brctl addif eth0
brctl addif eth1
3、从网桥中删除网卡 eth0 eth1
brctl delif eth0
brctl delif eth1
4、删除网桥 br0 ：
brctl delbr br0
在网桥上设置ip地址的命令：
ifconfig br0 xxx.xxx.xx.xxx netmask 255.255.xxx.xxx broadcast xxx.xxx.xx.xx
----------------------------------------------
添加磁盘：
1. 硬件
2. sudo fdisk -l
3. fdisk /dev/sdb (对新添加的硬盘（裸盘）做格式化:)
3. pvcreate /dev/sdc1 ( 建PV 前一步fdisk -l的设备名)
4. vgcreate vg_compute7RHEL6 /dev/sdb4 (建vg，前者为vg名，后者为设备名)
vgextend vg_compute3rhel6 /dev/sdc1 (建vg vg名 卷名)
5. 创建lv：
[root@compute7RHEL6 testcloud]# vgdisplay vg_compute7RHEL6 | grep "Total PE"
Total PE 119102
[root@compute7RHEL6 testcloud]# lvcreate -l 119102 vg_compute7RHEL6 -n lv1_hc
Logical volume "lv1_hc" created
6. lvextend /dev/mapper/vg_compute3rhel6-LogVol01 /dev/sdc1 (分区名[由df-lh得出] 卷名)
附：帮助信息：
