安装ceph luminous版本就可以解决了这个问题
2018-06-24 19:21:41 -0600 asked a question nova-computer 和 ceph jewel 关于librbd1版本冲突的问题

当我在安装ceph（jewel版本）后再安装 nova-computer-kvm将会失败。追踪了问题，主要是ceph使用的librbd1版本是10.2.9-0ubuntu0.16.04.1，但是nova-computer-libvirt 使用12.2.2-0ubuntu2~cloud0。我不知道如何去处理现在（在我不想通过源码编译ceph的情况下）。

PS：正常情况下，直接安装nova-computer 和ceph是没有问题的。但是这过程中并不会帮助你安装nova-computer-kvm，默认安装的是nova-computer-vmware，并且如果配置了compute_driver=libvirt.LibvirtDriver，会出现很多问题。

谁能够帮助我解决这个问题？

I has worked well a long time after the first install. When i do a system update action ,this issue appear。

I hava check the source as well,which is correct.

I do a test like below ,and ... (more)
