This was discussed here before so I'll just link to that earlier discussion: http://www.mail-archive.com/kvm@xxxxxxxxxxxxxxx/msg19890.html The attached patch is a bit of a hack, but at least it stops qemu-kvm from segfaulting when hardware virtualization isn't available.

Regression was introduced by this commit: http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commitdiff;h=b8083e930efc1ee85a7ad7e700dbd0f52ebb32dd Upstream discussion: http://www.mail-archive.com/kvm@xxxxxxxxxxxxxxx/msg19890.html Note: NOT UPSTREAM and this is something of a hack. Upstream are still debating how they really want to fix this. --- exec.c | 3 --- 1 files changed, 0 insertions(+), 3 deletions(-) diff --git a/exec.c b/exec.c index 705bcf2..2091516 100644 --- a/exec.c +++ b/exec.c @@ -422,9 +422,6 @@ static uint8_t static_code_gen_buffer[DEFAULT_CODE_GEN_BUFFER_SIZE]; static void code_gen_alloc(unsigned long tb_size) { - if (kvm_enabled()) - return; - #ifdef USE_STATIC_CODE_GEN_BUFFER code_gen_buffer = static_code_gen_buffer; code_gen_buffer_size = DEFAULT_CODE_GEN_BUFFER_SIZE; -- 1.6.4
