Hi all,
In current latest chageset (xen-ia64-unstable.hg cs:14762), PV-on-HVM
VNIF driver was broken by balloon driver introduced.
So, I'll submit temporary patch to resolve this issue, until we'll be
able to support balloon driver on HVM domain for IPF.
* vnif-wo-balloon.patch
- add dummy functions of balloon driver.
- Actually, current VNIF doesn't use balloon driver for PV-on-HVM,
but it calls balloon in the codes for flipping-receiver mode.
In our simple test, VNIF works in correct.
Thanks,
- Tsunehisa Doi
