If I recall correctly related issue was fixed in 4.9.

It's ugly.
I've reproduced the setup on my table, with the current master. It does
not work.
XEN allocated Dom0 memory properly:
    (XEN) *** LOADING DOMAIN 0 ***
    (XEN) Loading kernel from boot module @ 000000007a000000
    (XEN) Allocating 1:1 mappings totalling 2048MB for dom0:
    (XEN) BANK[0] 0x00000050000000-0x00000078000000 (640MB)
    (XEN) BANK[1] 0x00000600000000-0x00000640000000 (1024MB)
    (XEN) BANK[2] 0x00000718000000-0x00000730000000 (384MB)
    (XEN) Grant table range: 0x0000073fe00000-0x0000073fe64000

    (XEN) Loading dom0 DTB to 0x0000000058000000-0x000000005800fd09
    (XEN) Scrubbing Free RAM on 1 nodes using 4 CPUs
    (XEN) ........done.
    (XEN) Initial low memory virq threshold set at 0x4000 pages.

But my nfs-root is not mounted :(

Looking at the log, there is 640MB of RAM allocated below 4GB. So is it the same issue?

Also, which version of Xen are you comparing with?

Cheers,
