Hey @mfaridi1394 - Do you mind sharing the output of virt-host-validate and free?

It sounds like kvm2 can't allocate memory on your host, but I'm not sure why. It needs about 2GB of free RAM to setup a VM, but I'm not convinced that it's running low on memory here.

Thanks @tstromberg, how I set kvm2 use 1GB of RAM ?
I have RAM limitation

I have the same question. After searching, I think this issue may be helpful for you.

If you run into this issue, you have run out of system memory. You can try setting --memory for a lower number, but I suspect you can't get much lower than 1.9GB and still have a usable cluster.
