Re: [Xen-users] Reserved Memory release

I had temporarily started a VM, and it has allocated the memory for it. I have realised that after turning it down, the memory allocated to it, has remained reserved. Now, I need it for Dom0. So, how do I release the RAM that is reserved for VM, and make it available to Dom0? Is reboot the only option?

Changing the config won't affect a running DomU. Just a reboot won't help either - it needs to be a shutdown and then start it again.

But for memory, you can use xm mem-set to reduce memory usage in a running guest using the balloon driver.
