Hi,
just to be sure, if you run
kvm -vnc :1 -m 1.5G
kvm -vnc :1 -m 1.5G --no-hpet
do those also crash?
Can you please show the contents of
/var/log/libvirt/qemu/u1510-1.log
** Package changed: kvm (Ubuntu) => qemu (Ubuntu)
** Also affects: qemu
Importance: Undecided
Status: New
** Changed in: qemu (Ubuntu)
Status: New => Incomplete

I mean vm hang when memory >= 1100G (1024G when enable ide cdrom)
instead of 1.5G.
If disable hpet, the vm will hang at
acpi_ex_system_memory_space_handler when memory >= 1100G
If disable kvm, vm is good when memory <= 1020G, but also hang when
memory >= 1024G.
There is no critical information in vm.log:

After I changed PHYS_ADDR_MASK, qemu vm can start when memory >=1024G ,
but kvm vm still hang.
-# define PHYS_ADDR_MASK 0xffffffffffLL

I only saw this because it expired now :-/
Anyone affected by this might want to take a look at bug 1776189 where
Ubuntu added a special machine type to more easily set "host-phys-bits"
which is the qemu flag to have more (usually the host has more)
available (at the cost of migratability). That allows <1TB as the
default bits in qemu are chosen on the base of TCG (to be able to
emulate what is virtualized) and that is limited to 1TB.
