Oh, i see what you mean. Existing naming practice would suggest naming it -no-xenhv or just -no-xen All these '-no-XXX' args are getting a little silly though. I'd rather tell QEMU what I *do* want, than what I don't want. A generic arg '-accelerator none|xen|kvm|kqemu' might be worth considering in the future. That can be a separate discussion from these patches though - we should just follow the -no-XXX naming for now to minimize diffs Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
