Did you see any improvement with the change to the logger.conf? ----- Original Message ----- From: "Daniel Helgenberger" <daniel.helgenberger@m-box.de> To: users@ovirt.org Sent: Tuesday, July 1, 2014 2:38:18 PM Subject: Re: [ovirt-users] Spam Re: Spam Latency 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?

I noticed that the following operations take way, way too long:
Any type of import/export (VM, template. etc.) Disk migration Snapshot deletion
These operations take over 60 minutes, most of the time pushing 90 minutes. I know I don't have the fastest storage disks but wow, up to 90 minutes?. My NFS storage is on a 4 disk RAID 5. 7200rpm disks. 2GBps network connection.
Specs: Cluster of 4 Dell R420 Dual 6 core Xeon 32 GB Ram per server 4 500GB 7200 rpm disks RAID 5
