Please remove them and try again. What do you mean by "unsupported"? It's just OpenAFS from Squeeze backports: ii openafs-client 1.6.1-3~bpo60+1 ... ii openafs-modules-dkms 1.6.1-3~bpo60+1 ... Btw. we are running smaller cluster of 40 nodes with _same_ OpenAFS module without any problems (. The only difference is in QEMU, guest kernel and newer physical hardware: * host: ii qemu-kvm 1.0+dfsg-8~bpo60+1 ... * guest: ii linux-image-3.2.0-0.bpo.2-amd64 3.2.20-1~bpo60+1 ...
