Bug 1131609

+++ This bug was initially created as a clone of Bug #1093144 +++
Description of problem:

In RHEL7 beta I installed VMs with more than one drive using anaconda. When I do the same thing (the exact same anaconda configuration) but in RHEL7 RC1 it produces this:

ValueError: not enough free space in volume group

This seems to be regardless of the --size argument used. I gave it volume files as large as 50 GB and passed --size=12000, --size=1, --size=20000... nothing worked for RC1.

The anaconda file (well, the partition information segment) is this:

#----------------
zerombr
clearpart --all --initlabel --drives=sda,sdb

part raid.11 --size=500 --ondrive=sda
part raid.12 --size=1 --grow --ondrive=sda

part raid.21 --size=500 --ondrive=sdb
part raid.22 --size=12000 --grow --ondrive=sdb

raid /boot --fstype ext4 --device md1 --level=RAID1 raid.11 raid.21
raid pv.01 --device md0 --level=RAID1 raid.12 raid.22

volgroup sysvg pv.01
logvol / --vgname=sysvg --size=8000 --name=lv_root --fstype=ext4
logvol swap --vgname=sysvg --name=lv_swap --grow --size=1024 --maxsize=2048
logvol /mnt/edata --vgname=sysvg --size=1 --grow --name=mntedata
#----------------

Version-Release number of selected component (if applicable):

RHEL rc1

How reproducible:

Trying to install RHEL7 rc1 VMs using anaconda/qemu with two volumes rather than one (the latter worked fine for me). 

Please note again that the exact same configuration works fine for RHEL7 beta, I just tested it. Everything is the same - host, kickstart, IP, image file sizes, etc.

Steps to Reproduce:
1. Use two image files in kickstart rather than one as above.
2. Try to install
3. Get error message

Actual results:

ValueError: not enough free space in volume group

Expected results:

RHEL7 rc1 installs with two volumes.
