64bit VM Performance issues
Hey all,
I have this weird and unfortunately, quite urgent, issue with one of my VM's
First, let me give you a full overview of our setup:
2x HP DL380 G5 (2x 2,83Ghz Quad-core and 32GB RAM each) connected to an HP MSA2012i iSCSI SAN via Software iSCSI.
On these machines, I have about 10 VM's running without any problems. They are all running RHEL5.2 32bit.
Yesterday, I installed my first RHEL5.2 64bit machine. Allocated it 2 logical CPU's, 8GB of memory. Turned on VT in the BIOS of the hosts, started install and I had no issues during installation.
Now, however, I notice that performance in this VM is extremely bad, even when doing practically nothing. For example: untarring the VMware tools (35MB) took 2 full minutes! (No other VM's were present on the same host at the time of testing. This should have only taken seconds. I tried it again, this time with a top open and CPU skyrocketed to 100%.
Anybody, please. Help. 
Best regards,
Koen

Now, as far as multipathing is concerned, the SAN is an active/active array but only configured on 1 NIC at the moment because it's a preliminary setup before we move all servers to the datacenter. Could this be the problem? I filled in all 4 IP's for the SAN in the dynamic discovery tab of the software iSCSI initator and it should be able to find them all, as the SAN is fully patched to the switch. (this will of course be 2 switches in the final configuration).
