I suspect that's because the last entry in the list of packages to be installed is xen-tools.Here as well, some more information is required. What command are you using to install xen-tools? What is the output of the command?I think that it's possible to get around the problem by installing the xen-tools packages individually, but haven't done this yet.I don't understand this. As far as I know, xen-tools isn't a meta package, so how would you install the content of xen-tools individually?PaulHi Frank,I echo Paul`s questions, but would also just ask you to confirm whether I understand your setup and exactly what the problem is.So, I created a virtual Debian image and follow the steps one by one.I assumed that the the dom0 is the Debian, since I'm thinking that it's what starts the hypervisor. I didn't see anything in the tutorial about doing something different.First, am I right to think you`re trying to set up a complete xen environment, including dom0 (i.e. the hypervisor itself - the virtualization host) within a VirtualBox virtual machine? So it`s virtualization within virtualization?I've also tried to follow the tutorial using an old laptop. At some point I ran into what I've been calling the apt recursion problem.If so, I haven't tried it but conceptually I wonder whether it would be possible. Xen is a bare metal hypervisor. I think it may expect to be working with bare metal. I'm sure there are others more knowledgeable than me on this list who could say more definitively.Mostly the network is fine either way. It's just that apt-get doesn't work properly. Since I've been able to reproduce the problem now even on "bare metal" (a laptop ) I don't think that running second level is the problem. However, running a virtual machine makes it easier for me to transfer log files. (I now run everything I do as root under script, and keep the typescript output files.)Assuming it might be possible though, I get the sense you've installed a Linux environment (Debian if you're following the instructions) and are now trying to edit /etc/network/interfaces to match the text in the Beginner's Guide - i.e. to set up a bridge. When you do and then restart networking it no longer works - is that right? If you revert to the original interfaces file networking is fine?Paul: some more information is required. What are the two versions (o.k., not o.k.) of /etc/network/interfaces? What does ip a show in either case? Did you test connectivity (e.g. ping, DNS, etc.)? ----------------------------------------------------------------------------------------If that's it, I can see that the virtualized network card presented by VirtualBox may not mimic a hardware NIC completely enough to support the bridge.If so, it`s conceivable that there's a way around it using an alternative to the bridge like NAT, but it would be helpful if you would confirm whether the above does describe the problem. Even then, in the best case it may only get a network connection going, not the rest of xen.If I've misunderstood something, then maybe the answers to Paul's questions will help clarify.## Old version : New version source /etc/network/interfaces.d : = (unchanged) : = auto lo : = iface lo inet loopback : = : = allow-hotplug enp0s3 : = iface enp0s3 inet dhcp : iface enp0s3 inet manual : : auto xenbr0 : iface xenbr0 inet dhcp : bridge_ports enp0s3Paul: Here as well, some more information is required.

First, and I can't remember why, but I'm sure I had problems with apt-get too. Have you tried using apt instead? The commands are quite similar. I will check it out on my xen installation tomorrow, but I have used apt in place of apt-get for enough years that I've forgotten the precise details. Try that and let us know whether you have any more success. Second, the Beginner's Guide is okay at a fundamental level, but does have some quite old fashioned advice ("burn a CD") and cries out for a re-write. I'm not sure for example whether pygrub (as opposed to pvgrub) still works. (I haven't run up an installation from scratch in some time.) The Guide is quite out of date on pvgrub - it is fully functional and is preferred to pygrub - too bad the spelling is so similar. The section on PVH drivers is similarly out of date. Paul Leiber may have some specific notes on this. You may wonder at this state of affairs. There was an initiative last year to completely overhaul the xen documentation but it seems to have gone a bit dormant lately: https://xen-project.gitlab.io/people/agvallejo/xen-userguide/index.htmlIn the meantime we have been muddling along with the documentation as it is. I'm tempted to try to polish up the Guide as it stands since its content might inform the re-write even though the plan is to replace it completely in the near future. In any case, your feedback about trying out the Guide as it stands and any problems you run into will be helpful to either. Regards, David
