[Qemu-devel] [PATCH v2] xenfv: set has_acpi_build to false |

Xen's toolstack is in charge of building ACPI tables. Skip ACPI table
building and loading in QEMU by setting has_acpi_build to false for
xenfv machine.
This issue is discovered due to direct kernel boot on Xen doesn't boot
anymore, because the new ACPI tables cause the guest to exceed its
memory allocation limit.
