[CentOS] Installation of CentOS 6 on KVM - Hangs

Greetings-

I'm attempting to install CentOS-6 x86_64 to a virtual machine running via KVM on a Proxmox 1.9 system. The specs are 4x CPUs, 4GB RAM, and 160GB HDD. Installation proceeds fine using either minimal or netinstall CDs until installation of the selinux or qla2xx-firmware RPMs. At this point, the installation hangs, and never completes. I'm unable to see what is going on 'under the hood' on another TTY as the console does not appear to be accepting my CTL-ALT-Fx commands either.

I have also tried installing using the full bin DVD1, but the initial installation errors out immediately noting the yum package cannot be read from source disk/etc. And yes, I have checked the MD5s on all downloaded ISOs.

I can readily duplicate this. Any thoughts or pointers on the cause and/or solution?

Thanks!
