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
