As discussed in this VMware thread:Â http://communities.vmware.com/thread/413602
VMware converter 5 fails to recognize LVM slices on CentOS 6 or Red Hat 6.
Log files shows:
WARN storage.lvm ]: Failed to match lvs output line ‘Â lv_root|vg00|587034787840B|-wi-ao–|1
This issue is: -wi-ao–   converter is expecting: -wi-ao (no –)
Two fixes:
1. downgrade to:  lvm2-2.02.72
-or-
2. Wrap lvm with:
/sbin/lvm.wrapper $@ | sed -e ‘s/-wi-ao–/-wi-ao/’
