Subject: [PATCH] configure: Add --disable-kvm-options
|
|
|
c5cd36 |
|
|
|
c5cd36 |
In Fedora, our qemu package is based on qemu-kvm, and we go to convoluted
|
|
|
c5cd36 |
lengths to provide a qemu-kvm binary with KVM on by default, but all
|
|
|
c5cd36 |
qemu-system-* with KVM off by default (using ./configure --disable-kvm)
|
|
|
c5cd36 |
|
|
|
c5cd36 |
For qemu-system*, what we really want is upstream qemu symantics of TCG
|
|
|
c5cd36 |
by default, but the opt in option for KVM. CONFIG_KVM_OPTIONS fits the
|
|
|
c5cd36 |
bill, so let's expose it through ./configure. This will also simplify
|
|
|
c5cd36 |
our packaging for non-x86 KVM.
