Hi,
I'd like to know if there is a way to communicate the VM's guest OS
from the hypervisor node which hosts the VM.
As you know, Xen provide xenstore command to do it, I can use it to
pass some parameters into guest OS, is there a similar way in KVM?
Thanks in advance!
Regards,
Qian

There's an option to qemu that you could use, -net channel, to create a
vmchannel from the host userspace to the guest.
