If you are familiar with a standard RHEL based OS install, it usually creates two partitions on the OS disk. One for /boot and the other an LVM partition with /root, or whatever LVM layout you provide. I have noticed a behavior in converter where it is splitting these partitions into separate disk disks during a conversion. The v2v'ed host converts successfully, but I would prefer that converter would make a single vdisk with two partitions.
I have found a work around by resizing the disk /boot is on, creating a second partition of type LVM, extending the VG. Then mirroring the volumes, creaking the mirror and removing the second disk. This is mainly to keep with consistency. When you have over 500+ VMs that look one way, and you see an odd ball like this, it can throw you off. And possibly send you chasing a red herring to figure out why this host is different.
Anyway, If someone has seen this and found a more elegant solution, I would appreciate the feedback. If you are just going to ask if this is really an issue, the short answer is, no. I could really do without any pithy statements that don't address my question.
