OpenStack实现热迁移(live-migration)

[root@vmcom1-mn ~]#service nova-api stop
[root@vmcom1-mn ~]#service libvirt-bin stop
[root@vmcom1-mn ~]#find / -uid 106 -exec chown nova {} \; # note the 106 here is the old nova uid before the change
[root@vmcom1-mn ~]# find / -gid 107 -exec chgrp nova {} \; #note the 107 here is the old nova uid before the change
[root@vmcom1-mn ~]#service nova-api restart
[root@vmcom1-mn ~]#service libvirt-bin restart

2.修改各个节点的nova.conf
vncserver_proxyclient_address=本机ip
vncserver_listen=0.0.0.0
3.控制节点，配置nfs
apt-get install nfs-kernel-server portmap
在/etc/exports中加入/var/lib/nova/instances *(rw,sync,fsid=0,no_root_squash)
重新启动nfs服务,portmap服务
