Re: [libvirt] [PATCH 3/6] Deal with CPU models in []

Qemu committed a patch which list some CPU names in [] when asked for supported CPUs (qemu -cpu ?). Yet, it needs such CPUs to be passed without those square braces. When probing for supported CPU models, we can just strip the square braces and pretend we have never seen them. --- src/qemu/qemu_conf.c | 17 +++++++++++++---- 1 files changed, 13 insertions(+), 4 deletions(-) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index 0cbedf2..8577ff1 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -628,7 +628,9 @@ typedef int const char ***retcpus); /* Format: - * <arch> <model> + * <arch> <model> + * recent qemu encloses some model names in []:
