Description

My setup: KVM, Ceph datastore. 4.12

When attempting to attach block devices to the running instance the attachment fails when Device prefix is not selected or when "hd" is chosen, however, it works when either "vd" or "sd" are specified. This should default to either vd or sd when left blank so that attachment still works.

When not specifying a device prefix. or specifying "hd I get the following error:

Message received: LOG I 656 Command execution fail: /var/tmp/one/vmm/kvm/attach_disk 'one-656' '/var/lib/one//datastores/0/656/disk.9' 'hdb' '1'
