Hi, I think porterbox falla has been stable so far. Would it be possible to upgrade an actual buildd sto jessie oon, since at least package nss is waiting for this: https://buildd.debian.org/status/fetch.php?pkg=nss&arch=kfreebsd-amd64&ver=2%3A3.19.2-1&stamp=1434868643 Thanks, Regards, -- Steve

Also if either virtio-net is used, or booting from virtio-blk, Qemu 1.1.2+dfsg-6a+deb7u7 triggers a panic in atkbd driver on boot; Qemu 1:2.1+dfsg-12~bpo70+1 has fixed that however. I've completed test builds of glibc with ide and virtio-blk, which oddly showed no difference in build time. No sta

Hi, I've set up a clone of the buildds' KVM setup (without Ganeti), and with emulated IDE disks this is *crazy* slow. Do Linux buildd VMs also use if=ide, or is only kfreebsd using that? (Would make sense because, I don't think if=scsi is bootable, and if=virtio wasn't supported before kfreebsd-1
