Subject: [PATCH] pc: fail memory hot-plug/unplug with -no-acpi and Q35 machine
|
||
|
|
type
|
||
|
|
|
||
|
|
When -no-acpi option is used with Q35 machine type, no guest ACPI is
|
||
|
|
built, but the ACPI device is still created, so only checking the
|
||
|
|
presence of ACPI device before memory plug/unplug is not enough in
|
||
|
|
such cases. Check whether ACPI is disabled globally in addition and
|
||
|
|
fail memory plug/unplug if it's disabled.
