Hi

 

   I set up virtual machine with OpenNebula2.2 + NFS(NAS Huawei Symantec).
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.
