Check your alignment

New in libguestfs 1.13.18 is a tool to check your guest partitions are aligned for best performance.

virt-alignment-scan manual page

I found that all guests RHEL ≤ 5 & Windows < 2008 have poor partition alignment.

  1. Richard, sorry to post off topic…have you had a chance to look at the bitstring construction issue mentioned here: http://groups.google.com/group/bitstring/browse_thread/thread/9c644c034e75178d

  2. Great tool!
    For RHEL5 kickstart deployments there is a workaround to get partitions aligned in creating partitions in the %pre section. A document in the redhat.com customer center has details.
    Have not checked yet the outcome of RHEL5 deployments with this %pre with virt-alignment-scan thou.
