	virt-alignment-scan [--options]
	DESCRIPTION	DESCRIÇÃO
	When older operating systems install themselves, the partitioning tools place partitions at a sector misaligned with the underlying storage (commonly the first partition starts on sector C<63>). Misaligned partitions can result in an operating system issuing more I/O than should be necessary.
	The virt-alignment-scan tool checks the alignment of partitions in virtual machines and disk images and warns you if there are alignment problems.
	Currently there is no virt tool for fixing alignment problems. You can only reinstall the guest operating system. The following NetApp document summarises the problem and possible solutions: L<http://media.netapp.com/documents/tr-3747.pdf>
	OUTPUT	SAÍDA
	To run this tool on a disk image directly, use the I<-a> option:
	$ virt-alignment-scan -a winxp.img /dev/sda1 32256 512 bad (alignment < 4K)
	$ virt-alignment-scan -a fedora16.img /dev/sda1 1048576 1024K ok /dev/sda2 2097152 2048K ok /dev/sda3 526385152 2048K ok
	To run the tool on a guest known to libvirt, use the I<-d> option and possibly the I<-c> option:
	# virt-alignment-scan -d RHEL5 /dev/sda1 32256 512 bad (alignment < 4K) /dev/sda2 106928640 512 bad (alignment < 4K)
	$ virt-alignment-scan -c qemu:///system -d Win7TwoDisks /dev/sda1 1048576 1024K ok /dev/sda2 105906176 1024K ok /dev/sdb1 65536 64K ok
	Run virt-alignment-scan without any I<-a> or I<-d> options to scan all libvirt domains.
	# virt-alignment-scan F16x64:/dev/sda1 1048576 1024K ok F16x64:/dev/sda2 2097152 2048K ok F16x64:/dev/sda3 526385152 2048K ok
	The output consists of 4 or more whitespace-separated columns. Only the first 4 columns are significant if you want to parse this from a program. The columns are:
	col 1	col 1
	The device and partition name (eg. F</dev/sda1> meaning the first partition on the first block device).
	When listing all libvirt domains (no I<-a> or I<-d> option given) this column is prefixed by the libvirt name or UUID (if I<--uuid> is given). eg: C<WinXP:/dev/sda1>
	col 2	col 2
	the start of the partition in bytes
	col 3
	the alignment in bytes or Kbytes (eg. C<512> or C<4K>)
	col 4
	C<ok> if the alignment is best for performance, or C<bad> if the alignment can cause performance problems
	cols 5+
	optional free-text explanation.
	The exit code from the program changes depending on whether poorly aligned partitions were found. See L</EXIT STATUS> below.
	If you just want the exit code with no output, use the I<-q> option.
