 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

VDO，特别是它的内核模块，是专门为相关的RHEL/CentOS内核构建的。但是，您的服务器有OpenVZ，它使用自定义内核。此时，不支持在自定义内核中使用VDO。

为了安装这个程序，您需要获得kmod的源RPM，然后根据您希望它使用的特定it内核重新构建RPM。而且您可能也需要自定义它，因为它期望的是kernel而不是vzkernel。对于每个内核更新，您都需要重复这个过程。

看起来就像yum中的一个bug，防止安装，而且由于兼容性问题，它可能无法工作。寻找解决办法。
