Subject: qemu: Modify the structure _virDomainBlockIoTuneInfo.
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e34ffa96fb4344f122d491ebdb4679dfbaaa8857;p=libvirt.git

qemu: Modify the structure _virDomainBlockIoTuneInfo.

Modify the structure _virDomainBlockIoTuneInfo to support these the new
options.
Change the initialization of the variable expectedInfo in qemumonitorjsontest.c
to avoid compiling problem.
Add documentation about the new xml options
