Thank you. I will send you the result tomorrow. I wonder if nfs is widely used in opennebula cloud ? and is the vm running speed acceptable ?

And the virtualization environment is rhel6.1 + kvm. But the vm is running very slow. In the vm system, gunzip a gz file takes very long time. the nfs server(NAS) is suse10 with nfs version 3. the nfs client is rhel6.1 mount -t nfs -o timeo=10,noatime,intr,hard,retrans=5 172.16.14.115:/vx/B1ALL /one_images I tried to install two img systems at the same time on the nfs, the %CPU is high. and the installation progress takes very long too. So I wonder if the nfs can provide better performance for the vm ? How can I tune the nfs server and client parameters to enhance nfs performance ? Thank you very much. ---------------------------------------------------------------------------- ----------------------- Confidentiality Notice: The information contained in this e-mail and any accompanying attachment(s) is intended only for the use of the intended recipient and may be confidential and/or privileged of Neusoft Corporation, its subsidiaries and/or its affiliates.
