Hi,
I just tried to start a VM with libvirt with the following disk:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source protocol='rbd'
name='rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7'>
<host name='31.25.XX.XX' port='6789'/>
</source>
<target dev='vda' bus='virtio'/>
</disk>
That fails with: "Operation not supported"
I tried qemu-img:
qemu-img info
rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789
Same result.
I then tried:
qemu-img info
rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789:auth_supported=none
And that worked :)
This host does not have a local ceph.conf, all the parameters have to
come from the command line.
I know that recently auth_supported defaults to "cephx", but that now
break the libvirt integration since it doesn't set auth_supported to
explicitly none when no auth section is present.
Should this be something that gets fixed in librados or in libvirt?
Thought about it, this is something in libvirt :)
If it's libvirt, I'll write a patch for it :)
Just did so, very simple patch:
