一.為其他組分配instances：
1.進入192.168.77.51
2.如下操作：
查看images：
euca-describe-images
查看類型；
sudo nova-manage flavor list
選擇類型并啟動instances：
euca-run-instances ami-00000014 -t m1.hcType
獲取地址：
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
進入所在computer，查看VNC端口
ps -ef|grep instances | grep c8
VNC進入，修改防火墻和遠程鏈接，重啟instances：
euca-reboot-instances i-000000c8
------------------------------------------------
上傳模板：
glance add name="foranybackup" is_public=true < /home/testcloud/win-2003-x86_64.img --host=192.168.77.109
------------------------------------------------
卷相關：
sudo pvs
sudo vgs
sudo lvs
euca-describe-volumes
euca-attach-volume -i i-00000081 -d /dev/vdc vol-00000017
------------------------------------------------
自定義instance類型：
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啟動虛擬機：
創(chuàng)建鏡像：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節(jié)點所在機器
nova-manange service disable dev-compute* nova-compute
------------------------------------------------
多節(jié)點出現(xiàn)問題時候解決辦法：(重裝nova-computer服務)
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
----------------------------------------------
配置網(wǎng)橋
?brctl addbr br0
?brctl addif br0 eth0
增加網(wǎng)橋：
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
刪除網(wǎng)橋接口：
brctl delif? br0 eth0 eth1
刪除網(wǎng)橋：
brctl delbr? br0
關閉生成樹：
brctl stp br0 off
----------------------------------------------
1、創(chuàng)建網(wǎng)橋設備 br0：? brctl addbr br0
2、向br0中添加網(wǎng)卡 eth0? eth1
brctl addif eth0
brctl addif eth1
3、從網(wǎng)橋中刪除網(wǎng)卡 eth0 eth1
brctl delif eth0
brctl delif eth1
4、刪除網(wǎng)橋 br0 ：
brctl? delbr? br0
在網(wǎng)橋上設置ip地址的命令：
ifconfig? br0 xxx.xxx.xx.xxx? netmask? 255.255.xxx.xxx?? broadcast xxx.xxx.xx.xx
----------------------------------------------
添加磁盤：
1. 硬件
2. sudo fdisk -l
3. fdisk /dev/sdb?? ??? ??? ??? ??? ?(對新添加的硬盤（裸盤）做格式化:)
3. pvcreate /dev/sdc1?? ??? ??? ?(?? ?建PV?? ?前一步fdisk -l的設備名)
4. vgcreate vg_compute7RHEL6 /dev/sdb4 (建vg，前者為vg名，后者為設備名)
?? ?vgextend vg_compute3rhel6 /dev/sdc1?? ?(建vg?? ?vg名 卷名)
5. 創(chuàng)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?? ?(分區(qū)名[由df-lh得出]?? ?卷名)

附：幫助信息：
[root@compute7RHEL6 testcloud]# vgcreate --help
