Subject: [PATCH] hw/arm/virt: Reject gic-version=host for non-KVM
|
|
|
|
If you try to gic-version=host with TCG on a KVM aarch64 host,
|
|
qemu segfaults, since host requires KVM APIs.
|
|
|
|
Explicitly reject gic-version=host if KVM is not enabled
|
|
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1339977
|
|
(cherry picked from commit b1b3b0dd143b7995a7f4062966b80a2cf3e3c71e)
