Subject: [PATCH] qemu: Drop QEMU_CAPS_ENABLE_KVM
|
|
|
0a7476 |
|
|
|
0a7476 |
It was already available in 1.5.0.
|
|
|
0a7476 |
|
|
|
0a7476 |
Moreover, we're not even formatting it on the QEMU command
|
|
|
0a7476 |
line, ever: we just use it as part of some logic that decides
|
|
|
0a7476 |
whether KVM support should be advertised, and as it turns out
|
|
|
0a7476 |
that logic is actually buggy and dropping this capability
|
|
|
0a7476 |
fixes it.
