Just in case someone is interested in mapping RBD device on XenServer manually, here is the way how to do it.

 

Patch lvm.conf on all xenservers in the pool

-    types= [ "nvme", 64, "mtip32xx", 64 ]
+    types= [ "nvme", 64, "mtip32xx", 64 , "rbd", 64 ]

Map RBD device

# modprobe rbd
# /bin/echo "<ceph_monitor_ip_adresses> name=admin,secret=<admin_keyring> <poolname> <imagename>" > /sys/bus/rbd/add

Create device link 

# ln -s /dev/rbd1 /dev/disk/by-id/<poolname>-<imagename>

Create XenServer SR

# xe sr-create content-type=user device-config:device=/dev/disk/by-id/<poolname>-<imagename> name-label=”RBDSR” shared=true type=lvm
