The libvirt XML specifies memory in kilobytes, which means 512 rounds to zero. The fact that you can create a Xen guest is probably just because of a lack of verification. The QEMU command line takes memory in megabytes, so anything less than that isn't really valid. This was changed (fixed) in my recent patch to make the providers honor AllocationUnits in the MemRASD on DefineSystem(). DK> This value is *not sufficient* for creating a *KVM* guest, but is DK> *just enough* for *Xen, XenFV* guests. Perhaps just enough to create the guest, but not start it. Not even MS-DOS can run in 512 bytes of memory...

Indeed, which is why I wrote the (still unreviewed) test for AllocationUnits last week.

My test exercises all of the AllocationUnits paths. 40_RSC_start isn't the proper place for that, IMHO.

I think you should change the default VirtualQuantity to 32, and the AllocationUnits to "MegaBytes" for this case.
