via Red Hat Virtualization Manager for Windows Only? – InternetNews.com.
tl;dr – qumranet built it using WPF, redhat’s re-writing it but wanted to get RHEV out the door before thats done.
I’ve seen redhat’s closed-source aquisitions go fairly terribly (gfs/clustersuite, netscape directory server) so I gotta admit I have low hopes for this.
On the plus side, the comments learned me about “proxmox-ve”, gonna look at that more later.
