[libvirt] [PATCHv3] phyp: adding support for IVM
Eric Blake
eblake at redhat.com
Wed Jun 16 22:04:41 UTC 2010
From: Eduardo Otubo <otubo at linux.vnet.ibm.com>
Use virBuffer* API to contionally keep the portion of the command
line specific to HMC, so that IVM can work.
---
This starts from Eduardo's patch, then converts everything away from
using double virAsprintf (in the HVM case) over to using virBuffer.
