memory hot add oracle enterprise linux 5 update 5

Hello,

I trying to apply a memory hot add to a oracle enterprise linux 5 update 5 machine.

I checked the OS in the compatibility matrix and the memory hot add is supported.

I only can not seem to find a way to activated the added memory on the oel machine.

On a red hat linux machine it is no problem, that works, but I can not apply the same way of working on the oracle enterprise linux machine.

Does anyone have a solution on how to get this memory activated without rebooting the machine.

I tried to start the acpi_memhotplug module but I then get the error fatal: Module acpi_memhotplug not foud.

Thanks for the help.

Best regards,

JB

Is the CPU/Memory hot-add options been enabled in the settings of the VM?

yip. It is enabled.

And I can add memory to the virtual machine.

The thing I don't know is how to enable this added memory in my oracle enterprise linux 5.5 OS.

On a redhat system I use the following steps and it works great.

On the oracle enterprise linux system I can't apply these steps.

I increased the memory to the virtual machine.

how can I be sure that the memory is available to the guest?

What I don't have is this folder /sys/devices/system/memory

Under the system folder there isn't a memory folder.

Best regards,

JB
