rbd: failed to load rbd kernel module?

[athlon8048]

I have installed PVE on four Taishan Servers(CPU:Kunpeng 920 ),and update the system to version 8.3.2. When I created CT using cephpool, PVE displayed the ERROR messages as follow:
modinfo: ERROR: Module rbd not found.
modprobe: FATAL: Module rbd not found in directory /lib/modules/6.6.0-5-openeuler
rbd: failed to load rbd kernel module (1)
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: sysfs write failed

Then type the order : 'modprobe rbd' in shell, it displayed ' FATAL: Module rbd not found in directory /lib/modules/6.6.0.5-openeuler'
How can I solve it ? Thank you very much!
