--=-5mEvwVDwT1XAA2p5j2AH Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi Maurice, I have the same issue, and already read several other people noticing the same. IIRC (sadly I do not find the mails anymore, I keep the list only for one month) this may have something to do with log file noise, setting them to 'warning' may help, see below for an example. Since I observed high network IO with little no disk traffic, I suspect the disk image is converted to RAW and compressed again; making oVirt neartly unusable with multi terrabyte disk images (my test took about 3hs/TB). Can someone clarify the export / template creation process?
