I have experienced the same performance problem in creating new template or creating new stateful image from template. I have traced it to the use of qemu-img convert which is very very slow.
Currently a template creation on my setup, takes around 29m for a 45G image when a simple copy over NFS takes 1m26s over a 10G network which is expected since there is roughly as many read as write over the network (4Gbps) Adding --cache writeback to qemu-img improves from 29m to around 8m but according to a prior comment on this mailing list might not work on all platform. Hope that helps _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/XWUDXA47L72FUHT4DSHZTR634P5HMYIS/
