[libvirt] [PATCH 1/5] S390: Override QEMU_CAPS_NO_ACPI for s390x

[Viktor Mihajlovski]

Starting a KVM guest on s390 fails immediately. This is because
"qemu --help" reports -no-acpi even for the s390(x) architecture but
-no-acpi isn't supported there.
Workaround is to remove QEMU_CAPS_NO_ACPI from the capability set
after the version/capability extraction.
