1: This issue just happened on 32bit dom0.(the xen VMM is 64bit).
i have test on [VMM: xen4.4 (64bit) dom0 kernel 3.10 (64bit)], this issue can reproduce.
2: xen VMM e820 info:
(XEN) 0000000000000000 - 000000000009ac00 (usable)
.....................
(XEN) 0000000000100000 - 000000007df7f000 (usable)
.........................
(XEN) 0000000100000000 - 0000000880000000 (usable)
3: 32bit dom0 get host e820 info by XENMEM_machine_memory_map
[ 0.000000] Xen: 0000000000000000 - 000000000009a000 (usable
......
[ 0.000000] Xen: 0000000000100000 - 000000007df7f000 (usable)
.....
so the dom0 last_pfn = 0x7df7f
domo info:
[root@devserver-173 ~]# xl info | grep xen_commandline
xen_commandline : mem=1024G lowmem_emergency_pool=1M crashkernel=64M@32M loglvl=all guest_loglvl=all dom0_mem=3072M,max:3072M

Swap: 2096476 0 2096476
My Debug:
using the XENMEM_memory_map to get pseudo-e820 map on dom0, the dom0 mem can work correctly.
but the dom0 console is blank.

Hi ALL,
Environment
VMM: Xen-4.1.6.1
dom0: 3.0.101
Quesition:
Set dom0 mem using the kernel cmdline: dom0_mem=3072M,max:3072M, after booting, the dom0 mem is 1914M.
the others (3072M-1914M) has returned to xen vmm. maybe it is the e820 hole issue.
can you help me to fix this issue.
Thanks a lot
pls,
