[Qemu-devel] [Bug 1562653] Re: Ubuntu 15.10: QEMU VM hang if memory >= 1T

2019-05-22 Thread Christian Ehrhardt  
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.

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:

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?
