Hi Mike,

we do have such a thing and in principle this is possible. None the less, if I remember right, Reinhard has a something similar in preparation for another project. @Reinhard: Any news? I also think that compile-time shouldn't be an issue - worst case the package is published an hour later. If you've got a system up and running we should probably use that. Anyway the next two or three weeks are very busy for me, therefore I'd like to avoid doing this unless it is absolutely necessary until then.

Cheers.
Morty

Hi Morty, Reinhard, Arw,

Morty mentioned recently (I think in a Jabber session) that there is a build-server available at Uni Erlangen. Will it be possible to install qemubuilder on that system and use it for building X2go packages? I volunteer to do that, the qemubuilder can be used for other build jobs as well...

I have looked at the different systems available for package building and I liked qemubuilder best. However, qemubuilder does only build in kvm-mode on native systems (that is: not on already virtualized systems). In Intel-based kvm-VMs it can not access the VT technology of the CPU (so-called VT nesting).

However, AMD Pacifica CPUs support KVM nesting (never tried it out, though). @Morty: if you run VMs on an AMD CPU that would also be great and functional for our needs.

Anyone else: if you can provide such a build server, please let me know that, too. I currently use my notebook for building X2go packages (it is a really fast one, but still, it is a notebook). The server behind code.x2go.org also runs a similar qemubuilder setup, but it only falls back to slow qemu software emulation as it already as a virtual machine...

Any help is appreciated,
Thanks a lot Mike
