It'd be great to be able to create a virtual machine on my local computer (Ubuntu as guest OS) and start off running it there. Then, when I need more power, upload it to a VM hosting provider and run it there.
With Mac computers, is there any combination of e.g. VMWare Fusion, Parallels, Linode, & AWS that'd enable this? E.g., download a Linode and run it locally.
EDIT: Amazon apparently supports this "You can import VMware ESX VMDK images, Citrix Xen VHD images and Microsoft Hyper-V VHD images for Microsoft Windows Server 2003 R2 and 2008 R1 and R2. You can export previously imported EC2 instances to VMware ESX VMDK, VMware ESX OVA, Microsoft Hyper-V VHD or Citrix Xen VHD file formats."
So now the question is, what desktop software (for Mac) supports these images?
