Resized VM won't power on - hotplug error from VMware

Hi there,

A customer has deployed a VM via OpenNebula, they powered down the VM after approx 1 month while building the VM to increase the memory.

They performed the resize, increasing the memory to 6GB while the VM was powered off, powering on fails with a hotplug error.

– deploy failed, back to powered off –

By default hot plugging is disabled on VMs in VMware, strange how this is a hotplug task when the VM is powered off.

Does anyone have experience with this issue or suggest and areas to check?

I will be doing a screenshare to understand their steps and reproduce.

Thanks in advance,
Derek

Just updating this to mention the issue was due the customers RedHat cluster configuration.

Something to do with their cluster vCenter fencing was booting the VM again, explaining the hotplug error - the VM was actually running again by the time the resize was occurring.
