libvirt_storage_backend_rbd.so报错及解决方法

虚拟化服务libvirtd无法正常启动,报错:error : virModuleLoadFile:53 : internal error: Failed to load module ‘/usr/lib64/libvirt/storag  e-backend/libvirt_storage_backend_rbd.so’: /usr/lib64/libvirt/storage-backend/libvirt_storage_backend_rbd.so: undefined symbol: rbd_diff_iterate2 。

问题原因:older version of libvirt-daemon-driver-storage-rbd usually used in older RHEL 7.x version which is missing the librbd1 dependency。(动态链接库缺失)

具体可以通过如下方法查看:

[[email protected] storage-backend]# file libvirt_storage_backend_rbd.solibvirt_storage_backend_rbd.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=f0289019f4ff9a0c87c47c928457be3672448e47, stripped

缺失的链接库文件在librbd1包里,解决方法如下:

yum update librbd1systemctl restart libvirtd
