Thanks for testing! Let me know when it works for you. Xen 4.2 is only in experimental at the moment and I'd rather keep the list of deps from experimental short until wheezy is released.` Cheers, -- Guido > > Cheers, > Xiao-Long Chen -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

But if you look at the source code: http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/libxl/libxl_driver.c;h=a8c4cae0e509a09e76ea344e3c0826cea04bfd71;hb=HEAD#l971 On line 971, libvirt will run "/usr/sbin/xend status" to check if xend is running. If so, libxl falls back to xend. Of course, just because something is in the source doesn't mean it works correctly :) I'll test it to make sure.

No. Libvirt doesn't setup the hypervisor it "only" looks for available ones.

As far as I know, libvirt will automaticallyfall back to the current xen driver if xend is running. It will only use xl ifxend is not started. Am I correct to assume that any existing libvirt configuration for xen wouldhave xend started automatically as it is required? Cheers,Xiao-Long Chen

We need to offer a migration path for existing configurations. Do you want to work on that?
