That's right. That's the Linux guest side implementation. For windows we use the vmchannel option in qemu (qemu/hw/hypercall) interface. It is a qemu device from the host side that can be connected to tcp/unix socket. The guest sees it as a pci device. Both ends can define any protocol over the channel. So our windows guest passes balloon inflate/deflate commands/acks. What's your motivation of ballooning? If it's important I can add the pci interface + push it upstream. > >So we cannot balloon up/down a guest from host machine? > >I will try to see if it works. > >Thanks, >Jun ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
