[Spacewalk-list] Was: Re: Spacewalk Issue - CentOS kickstarting

[John Holland]

  I just discovered something - maybe everyone on the list already knows 
- it appears that CentosOS and Fedora guests in KVM booting off of PXE 
from Spacewalk work a lot better with "IDE" virtual disks than with 
"Virtio". I'm used to Satellite and RedHat where VirtIO is preferred. 
Have I reached a correct conclusion, that IDE is better for Spacewalk?
