Hi yunhong, I agree with you of the taking I/O bandwidth as a resource, but it may be not so easy to implement. Your another thinking about the launch time may be not so terrible, only the first boot it will be affected. 2014-02-17 Wangpan 发件人:yunhong jiang 发送时间:2014-02-15 08:21 主题:Re

[openstack-dev] [nova] Should we limit the disk IO bandwidth in copy_image while creating new instance?

2014-02-13 Thread Wangpan
Currently nova doesn't limit the disk IO bandwidth in copy_image() method while creating a new instance, so the other instances on this host may be affected by this high disk IO consuming operation, and some time-sensitive business(e.g RDS instance with heartbeat) may be switched between master
