Often in experimental state, but nevertheless. >We have the technology for VMs. Actually, we don't for PowerPC. Right now, you have two options for virt on ppc/ppc64: 1) kvm for PPC 440. Fedora doesn't support PPC 440 (it could, but it's an embedded CPU and would require yet another kernel.) 2) LPARs for ppc64. This is actually a bit more feasible, but it requires you to have a POWER machine with LPAR support configured. Most of the existing builders are blades, which generally don't do LPARs. josh -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
