[Users] Virtual Disk creation - really slow (config issue?) e.g 20GB disk created in 23 mins - NFS server/Gigabit switch - can anyone suggest why speed is so slow ? (at this rate it would take 1hr 40 mins to create a 100GB disk...)

Hi. After my many issues with spice I have finally sorted them out. Now I am having an issue with the speed of virtual disk creation - when I go to create a virtual disk it takes a long time (far to long to be usable) My setup is as following 3 servers:- 1 Frontend (ovirt engine) - Fedora 16 - external + local IP (91.215.xxx.xx + 10.0.0.10) 1 Ovirt node (using the node .iso) - external + local IP (ovirtmgmt (eth0) - 91.215.xxx.xxx and LAN (eth1) - 10.0.0.101) 1 NFS storage - external + local IP - I attached the storage using the Local IP (10.0.0.190) All servers are connected via a Gigabit switch (so speed should be better) I can scp between servers far faster - I'm almost sure its due to the node ovirtmgmt address being an external (internet ip) and not LAN ip. - therefore the traffic is not just going over the gigabit switch but via the core router in the DC... Can anyone suggest how I can 'debug' where the slowness is coming from On my NFS server I have it setup like (in /etc/exports) /storage1 *(rw,sync,no_subtree_check) I had previous tried setting up the node on a LAN IP previously and it caused spice to not work - as the node had no internet access / DNS - I also tried making the frontend server a gateway (and using - iptables -t nat -A POSTROUTING -j MASQUERADE ) - this also cause spice to not work (as it always tried to connect to the 10.0.0.x address from my desktop - and fail..) Any hints/help will be welcomed Cheers
