(I also needed the other patch when testing from your branch: "remote_daemon: Validate tcp_min_ssf value only if found in config"). So compiled with: $> git describe v7.9.0-94-gc39356148c Still works fine for me. Two quick tests: (1) With only <domain type='qemu'>, libvirt now uses `-accel tcg` unconditionally. (As opposed to `-machine accel`) (2) And adding the `tb-cache` bit: <features> <tcg> <tb-cache unit='KiB'>65536</tb-cache> </tcg> </features> ... results in QEMU command-line: `-accel tcg,tb-size=64` Series: Tested-by: Kashyap Chamarthy <kchamart@xxxxxxxxxx> Thanks for the quick work! -- /kashyap
