Note that “allow_resize_to_same_host” doesn’t force it to stay on the same host, it only allows it to happen. It’s still up to the scheduler as to where it goes. Because we use shared storage at Overstock, we had to work around this by disabling all the hypervisors except the one it’s on before doing a resize.
We also would love to see a way to prevent copying the disk when the size doesn’t change. It’s annoying when you just want to make a CPU or RAM change and have to wait for the disk copy. The other downside of resizing is that it changes your nice, sparsely-provisioned copy-on-write disk image into a full size image divorced from the qcow source disk.
