Just shutdown the VM, change the amount of memory and start again.

However, the changes are only applied after the VM has been rebooted.

I found the following information from the document of XenServer. "All writable VM parameter values can be changed while the VM is running, but the new parameters are not applied dynamically and will not be applied until the VM is rebooted." Does it mean changing VM settings using comman line？If I change the CPU and memory settings of XenServer virtual machines using the API, do I have to reboot the VM to make the settings work？ Looking forward to your reply.Please contact with me through email: kongshoubin@gmail.com Thank you very much.

Is there a way that the VMs ( lets say Win Server or RHEL) can start up with Xentools.iso ? I want to automate monitoring the IP that the machine gets through DHCP and the VM memory which can be done through Xentools.iso installation but this needs to be separate . I have tried installing xentools and converting it into a template and then instantiating a VM but this process doesn't work. Can this be done through API ? Thoughts ? Thanks Madhurranjan Good article!!
