Marc: Here's a template that works here. You'll need to do some steps to create the 'secret' and make the block devs and so on: <disk type="network" device="disk"> <driver name="qemu" type="raw" cache="writeback"/> <auth username="libvirt"> <secret type="ceph" uuid="3fc5de60-358e-e010-93c9-bacfc9636edf"/> </auth> <source protocol="rbd" name="yournamespace/yourblockdevname" index="1"> <host name="yourmon1" port="6789"/> <host name="yourmon2" port="6789"/> <host name="yourmon3" port="6789"/> <host name="yourmon4" port="6789"/> </source> <target dev="vda" bus="virtio"/> <alias name="virtio-disk0"/> <address type="pci" domain="0x0000" bus="0x00" slot="0x07" function="0x0"/> </disk> Glad I could contribute something. Sure would appreciate leads for the suggested sysctls/etc either apart or as tuned profiles.
