Re: [Xen-devel] RAMDISK-Boot: Not enough RAM for domain 0 allocation.

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

Xen wants to allocate smallest power-of-two sized memory block which will
fit both kernel and initrd. This will be 2GB on your system, and there is no
such 2GB aligned block. Either this restriction of the domain builder needs
to be lifted (a bit of a pain and not really on anyone's todo list), or you
could just reduce your initrd size by 100MB and cross your fingers -- it's
likely that Xen will be able to find an aligned 1GB memory block.
