Why does Fedora assign 99% to all phsical memory to Domain-0 ? Dom0 gets essentially 100% of all memory at boot time. XenD will use the balloon driver to take memory away from Dom0 when it is needed to launch a new guest. Of course this relies on you not actively using that memory in Dom0 but in general it just works. If balooning were failing though you would see a different error - one saying it was unable to balloon down the dom0. The 'cannot allocate memory' error suggests a more fundamental problem. > 2. Why does this memory allocation error happen with the Windows Guest? Running 'xm dmesg' shortly after creating the guest may be helpful in tracking down actual errors.
