Hi,
I am running a research project at my university. Primary goal is the comparison of different virtualization systems (Hyper-V, OpenVZ, Xen and VmWare). For disk (iscsi) and network performance I am using a slightly modified IOMeter benchmark (client server modification to eliminate possible timing issues in the virtual machine). At any rate, IOMeter tries accessing "/proc/partitions", which fails for obvious reasons. Is there a way around this? I'd appreciate any help. Below is the full terminal output:
root@1234:/home/tests# ./dynamo -i 192.168.234.1 -n 1234 -m 192.168.234.5
Fail to open kstat device file. You can ignore this warning
unless you are running dynamo on XSCALE CPU.
Command line parameter(s):
Looking for Iometer on "192.168.234.1"
New manager name is "1234"
Sending login request...
1234
192.168.234.5 (port 45695)
Successful PortTCP::Connect
- port name: 192.168.234.1
*** If dynamo and iometer hangs here, please make sure
*** you use a correct -m <manager_computer_name> that
*** can ping from iometer machine. use IP if need.
