--_000_D86C48DF8800164BBE50B87623F7AC9585D0624Dln2wio001devtra_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable I'm trying to use the vhostmd vdsm host to access ovirt node metrics from w= ithin a VM. Vhostmd is running and updating the /dev/shm/vhostmd0 on the ov= irt node. The part I'm stuck on is: "This disk image is exported read-only to guests.= Guests can read the disk image to see metrics" from http://www.ovirt.org/d= evelop/developer-guide/vdsm/hook/vhostmd/ Does the hook do this by default? I don't see any new read-only device moun= ted in the guest. Is there additional work I need to do to mount this and a= ccess the data from within the guest?
