OK, vvIoS2-fZTZ-99Ox-Ltzq-pr8U-SL2z-wbTU8g is the uuid of the VG that
engine says that it includes the LUN used by the hosted-engine SD as
detected by the engine.
Its name is 6b62cc06-fc44-4c38-af6d-bfd9cbe73246 which is also the uuid of
that storage domain.
Now we need to understand what's there.
Could you please check if an SD with uuid
6b62cc06-fc44-4c38-af6d-bfd9cbe73246 is visible in the engine?
Is adm-kvmh70 involved in hosted-engine? did you redeployed it?
In the past did you tried to manually import the hosted-engine SD or
something similar?
