HI guys,
I have got a problem with the IO performance of my kvm nodes.
One kvm node is setup up on a kvmhost. This host has got an nfs mount from the
mgmt node.
If I do a throughput test on this nfs share, I get ~ 112 MB/s. But within the
kvm node I just get 11 MB/s.
I saw some possibilitys to set the vmstorageformat but xcat complains about not
knowing this option (fresh installed xcat, newest version). Also tabedit vm
shows no such option (Also storagecache etc).
Thought I can switch from qcow2 to raw or something equal.
Anny suggestions on the missing option or the whole problem?
Thanks a lot!
