right now I have 6 Virtual Machines (VMs) running on Vmware ESXi 5.1 and attached to Storage SAN.
All these run Suse Linux 11 SP1 x64.
All of a sudden 1 of these VMs is running very slow making high CPU usage and I see al wait % kinda high 40-50%. Apparently since I don't own this virtual server the server was running fine and last change made was increasing memory
so I found out that test hard disk performance must be the issue
VM having issues. It so slow that I cancel the command but it's running at 2.7 MB
running dd command on any of the other VMs linux server is about 280MB - 310 MB/s
any idea what could be causing this issue or how to fix it?
It seems this can happen after a move of the VM.
Work-around: switch auto-move off for SuSE VMs. Manually move them, and reboot them if performance becomes bad and/or system load becomes high.
