Description of problem:
I see random failures when trying to install RHEL 6.0 Beta 2 inside a KVM guest running on Fedora 13 x86_64 host.

Version-Release number of selected component (if applicable):
6.0 Beta 2

How reproducible:
25% to 40% of test installs fail

Steps to Reproduce:
1. install F13 x86_64 on IBM LS21
2. fully update F13
3. create a LV for the KVM guest (either by allowing virt-install on the first test run to create an LV or vie virt-manager) and use that LV for all future tests
4. configure bridged networking (doubtful this is related, but both on my tests at home yesterday and the tests on LS21 today, I do use bridged networking)
5. virt-install -n 512test -r 512 --vcpus=1 --location=ftp://myserver/pub/RHEL-6.0-Beta-2/Server/x86_64/os -x "console=ttyS0,115200 ks=http://myserver/kickstart/pcfe/RHEL60-beta2-minimaltesting-x86_64-ks.cfg" --os-type=linux --os-variant=rhel6 --nographics --hvm --disk vol=vg_bcblade02/KVM_512_test --network bridge=br0
6. if install went through fine, disconnect from console
7. virsh destroy 512test ; virsh undefine 512test
8. repeat steps 5 through 7 a few times (I did 10 testruns)
  
Actual results:
between 25% and 40% of the installs fail

Expected results:
deterministic install results

Additional info: (please do not mind the odd formatting, gnome sticky notes on my notebook is acting up and was refusing me to copy from th enote directly, so I extraced my failure notes from it's file)
