Jan, After my most recent pull from qemu git master, I realized I can no longer use '-monitor stdio' together with '-enable-kvm'. They each work separately, but when used together, qemu dies with the following error:
$ bin/qemu-system-x86_64 -enable-kvm -monitor stdio failed to initialize KVM: Interrupted system call No accelerator found! I did a git bisect and the culprit appears to be commit ac4119c023c72b15f54238af43e4a178fcf41494 (chardev: Use timer instead of bottom-half to postpone open event) Thanks, --Gabriel
