H A Dtest_mem_addr_space.py28 access up to a maximum of 64GiB of memory. Memory hotplug region begins
29 at 4 GiB boundary when "above_4g_mem_size" is 0 (this would be true when
30 we have 0.5 GiB of VM memory, see pc_q35_init()). This means total
31 hotpluggable memory size is 60 GiB. Per slot, we reserve 1 GiB of memory
33 actual memory size of 59 GiB. If the VM is started with 0.5 GiB of
34 memory, maxmem should be set to a maximum value of 59.5 GiB to ensure
55 access up to a maximum of 64GiB of memory. Rest is the same as the case
121 so it can access physical address up to 4 GiB. Setting maxmem to
122 4 GiB should make QEMU fail to start with "phys-bits too low"
124 above 4 GiB due to the PCI hole and simplicity.
