The problem with this is if I'm using TCG fallback mode, how can I specify the right gic-version? ie: -M virt,gic-version=host,accel=kvm:tcg Only qemu knows if KVM is going to be enabled. The same problem happens with '-cpu host' BTW. I really want a "make it work" option, as I've said on several previous occasions on this list eg: https://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg04173.html Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-p2v converts physical machines to virtual machines.
