Hello Everybody!

I'd like to find a way to pass information between a machine & a virtual machine managed by libvirt (like we can with VirtualBox or VMware thanks to guest tools for instance ). I thought that I would have been able to write a comment section or something like that within the xml description of the right domain, but every new comments or xml tags are erased once I save them... Maybe somebody's got an idea to help me :D...

There isn't any explicit direct way to pass information into the guest. Some other options though - Add an extra NIC, but don't connect it to the main host OS public network. So host can talk to guest via the NIC & vica-verca, but outside world can't see it. - Create a ISO / floppy disk image put files in it and add this disk to the guest - For Linux only, if you're booting off kenrel+initrd, you can pass a limited amount of info via the 'cmdline' args parameter 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 :|
