Hi, thanks for your response.
Having said that, there is probably a bug in Horizon since it's
defaulting to vda for the device name when booting from volume.
I think so, too. I'm quite new to Openstack and not 100% sure about my
statements, but I think my question is not a support issue. I'm trying
to find the cause for the faulty results when launching instances from
volume via dashboard.
The libvirt driver in nova ignores the requested device name in boot
from volume / volume attach requests
Yes, I see that, too, in default_device_names_for_instance() the
bdm.device_name is nulled out. But there is also a "root_device_name",
which keeps the value provided by a user (CLI or Horizon) and this
value is applied when trying to boot from that volume, which leads to
an error. Shouldn't the root_device_name also be nulled out?
Sorry, if this is not the right channel to address this issue, I
thought it was. So if it's not, what is the way to go here?
Regards,
Eugen

Hi Eugen!

The libvirt driver in nova ignores the requested device name in boot
from volume / volume attach requests since Liberty [1]. It's best to
let the virt driver in nova pick the device name, you can get the
mountpoint via the volume attachment later after the volume's status
is 'in-use'.
