Re: [libvirt] how to pass qemu options?

Ditto for other qemu options such as "-soundhw all". Is there a way? Not directly in the config. Usual trick is to create a wrapper script like this (for a serial console in that case) ... [root@xeni f8-32]# cat /root/bin/qemu-serial #!/bin/sh exec /usr/bin/qemu-kvm "$@" -serial telnet::9999,server,nowait,nodelay ... then edit the xml config to make the <emulator> tag point to the wrapper script instead of /usr/bin/qemu-kvm.

Hmm, maybe the emulator tag should get a args attribute, so one can do that kind of stuff without wrapper scripts, like this: <domain type='kvm'> [ ... ] <devices> <emulator args="-redir ...">/usr/bin/qemu-kvm</emulator> [ ... ]

The usual ones should be supported by libvirt directly of course. Serial console is in cvs meanwhile, I've seen also sound support patches. But for unusual configurations and debugging purposes it would be quite handy to have the additional args directly in the config and not hidden somewhere in a separate script ... comments?
