Subject: qemu: command: Drop obsolete comment
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=388b356e5d27e571d603558c5eb8588a453fa448;p=libvirt.git

qemu: command: Drop obsolete comment

The change that made qemu not add the memballoon by default happened
prior to 0.12.0. Additionaly the comment was misleading due to the code
that was added below. Since we always need to add a balloon on the
commandline drop the comment.
