Hello, snapshot are meant to be backups. I would not install software on a machine, and then use the snapshot as a glance image to start many new instances. you could just create machines with a clean glance image and install the necessary software with ansible/puppet if the installation time at boot is too long, you could create glance images with the software you need with the diskimage-builder creating a new dib. Look at this example of a ubuntu glance image with zeppelin and spark preinstalled: https://github.com/switch-ch/diskimage-builder/tree/SWITCHengines/elements/zeppelin Saverio 2016-11-22 7:44 GMT+01:00 Jack Gao <jack.gao.ch at gmail.com>: > Hi everyone， > > I am using a virtual machine to create a snapshot, and then use this > snapshot to create other virtual machines.Will encounter residual data > didn't clean the problem, this will lead to network card information is > inaccurate, puppet certificate conflict etc. > > The current practice is to use the sys-virtprep tools manual cleaning, > within the opesntack system, whether to have a better solution? > > Regards. > > _______________________________________________ > OpenStack-operators mailing list > OpenStack-operators at lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators >
