I have 3 domU running on a single server.
Domain "clas-0" is exporting a directory to
domain "dbn-0" via NFS.
Both "clas-0" and
"dbn-0" has time synchronisation from another external server.
Both "clas-0" and "dbn-0" each has HDD file size
of 50G.
I can ssh into both "clas-0' and
"dbn-0" normally ; login response is acceptable.
Each domU has only a single virtual bridge.
There is only one physical interface in the host machine, ie each domU
virtual interface is bridged into a single interface.
"/var/log/xen/xend.log" file does not indicate any
errors.
At time of writing right now, "dbn-0" is creating
an Oracle database instance of 30G.
My problem is that the domain "dbn-0" is
creating the oracle instance very slowly.
I
do not know where the problem lies.
Therefore I appreciate your advice on this, or any directions to
identify the bottlenecks.
Thanks.
