This problem has nothing to do with apt-get install but is instead somehow related to the bridged adapter update earlier in the Wiki. Reverting that change to /etc/network/interfaces removes the problem (and also makes apt-get run a lot faster.) -------------------------------------- Earlier message: Hi, (I'm not really a Xen user yet, I'm just going through the beginner's installation guide on the Wiki: https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide) I can't install Debian xen-tools because it doesn't complete, it just starts over again. I suspect that's because the last entry in the list of packages to be installed is xen-tools. I think that it's possible to get around the problem by installing the xen-tools packages individually, but haven't done this yet.

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? 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. 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? 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.

As David Hill asked first, are you sure you really want to do *this*? While running a hypervisor on a hypervisor is possible in theory, x86 makes this *extremely* difficult. Starting by running Linux on Xen and letting Domain 0 take the entire machine is likely similar to the environment you're thinking of.

This sounds like you're trying to install Xen from source, yet you're starting from a Debian Linux installation. Are you sure this is what you desire? I suspect you might instead want to start looking at Debian's wiki: https://wiki.debian.org/Xen I though would suggest starting by running: `apt install xen-system grub-xen-host` (the Debian wiki's recommendation of `apt install xen-hypervisor` leaves the utilities uninstalled and that isn't too helpful) Once you're a bit futher along, https://wiki.debian.org/PvGrub is rather valuable (this is why I suggest grub-xen-host). -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sigmsg@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445 From xen-users-bounces@lists.xenproject.org Tue Apr 15 09:36:43 2025 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Tue, 15 Apr 2025 09:36:43 +0000 Received: from list by lists.xenproject.org with outflank-mailman.952359.1347832 (Exim 4.92) (envelope-from ) id 1u4ci2-0007qE-MI; Tue, 15 Apr 2025 09:36:02 +0000 X-Outflank-Mailman: Message body and most headers restored to incoming version Received: by outflank-mailman (output) from mailman id 952359.1347832; Tue, 15 Apr 2025 09:36:02 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4ci2-0007q2-JL; Tue, 15 Apr 2025 09:36:02 +0000 Received: by outflank-mailman (input) for mailman id 952359; Tue, 15 Apr 2025 09:36:01 +0000 Received: from se1-gles-sth1-in.inumbo.com ([159.253.27.254] helo=se1-gles-sth1.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4ci1-0007pw-LT for xen-users@lists.xenproject.org; Tue, 15 Apr 2025 09:36:01 +0000 Received: from mx2.isp.ktk.de (mx2.isp.ktk.de [82.115.96.229]) by se1-gles-sth1.inumbo.com (Halon) with ESMTPS id 0a8018e0-19dd-11f0-9eae-5ba50f476ded; Tue, 15 Apr 2025 11:36:00 +0200 (CEST) Received: from mail.ktk.de (tmo-123-63.customers.d1-online.com [80.187.123.63]) by mx2.isp.ktk.de (Postfix) with ESMTPA id 4ZcJtk5lVbz4db for ; Tue, 15 Apr 2025 11:35:58 +0200 (CEST) Received: from [192.168.42.2] (worknm [192.168.42.2]) by donald.local (Postfix) with ESMTP id 3B9BFA0358 for ; Tue, 15 Apr 2025 11:35:44 +0200 (CEST) X-BeenThere: xen-users@lists.xenproject.org List-Id: Xen user discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Errors-To: xen-users-bounces@lists.xenproject.org Precedence: list Sender: "Xen-users" X-Inumbo-ID: 0a8018e0-19dd-11f0-9eae-5ba50f476ded Subject: Re: apt-get install xen-tools recursion Cc: xen-users@lists.xenproject.org References: <50901fa5-d0d6-4f82-ab17-baf30141ce84@gmail.com> From: "Manfred Haertel, DB3HM" Message-ID: Date: Tue, 15 Apr 2025 11:35:45 +0200 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0 SeaMonkey/2.53.20 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Elliott Mitchell schrieb: >> I should have mentioned that I'm testing the installation procedure using a >> VirtualBox virtual machine. > > As David Hill asked first, are you sure you really want to do *this*? > > While running a hypervisor on a hypervisor is possible in theory, x86 > makes this *extremely* difficult.

Proper hypervisor on hypervisor should be indistinguishable from hypervisor on "bare metal". Similarly an OS running on a hypervisor *shouldn't* be able to tell the hypervisor is there. x86 makes this extremely difficult since many instructions behave differently in the different modes. Certainly there are workarounds, but those glitches shouldn't be present in the first place. Compare PowerPC which has a very carefully designed model and full virtualization is easy. You still want psuedo-devices which don't behave anything like actual storage devices, but you can readily hide the processor bits of virtualization. ARM is a bit in-between. It doesn't have all the hard to simulate quirks of x86, but does have hard borders between EL0-EL2. As such there are information leaks, but not nearly as many as x86. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sigmsg@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445 From xen-users-bounces@lists.xenproject.org Wed Apr 16 03:31:35 2025 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 16 Apr 2025 03:31:35 +0000 Received: from list by lists.xenproject.org with outflank-mailman.954808.1348761 (Exim 4.92) (envelope-from ) id 1u4tTa-0004Vf-99; Wed, 16 Apr 2025 03:30:14 +0000 X-Outflank-Mailman: Message body and most headers restored to incoming version Received: by outflank-mailman (output) from mailman id 954808.1348761; Wed, 16 Apr 2025 03:30:14 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4tTa-0004VY-4v; Wed, 16 Apr 2025 03:30:14 +0000 Received: by outflank-mailman (input) for mailman id 954808; Wed, 16 Apr 2025 03:30:13 +0000 Received: from se1-gles-flk1-in.inumbo.com ([94.247.172.50] helo=se1-gles-flk1.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4tTZ-0004VR-4S for xen-users@lists.xenproject.org; Wed, 16 Apr 2025 03:30:13 +0000 Received: from mx1.isp.ktk.de (mx1.isp.ktk.de [82.115.96.228]) by se1-gles-flk1.inumbo.com (Halon) with ESMTPS id 1806b27e-1a73-11f0-9ffb-bf95429c2676; Wed, 16 Apr 2025 05:30:07 +0200 (CEST) Received: from mail.ktk.de (tmo-085-147.customers.d1-online.com [80.187.85.147]) by mx1.isp.ktk.de (Postfix) with ESMTPA id 4Zcmk6202Lz248k for ; Wed, 16 Apr 2025 05:30:06 +0200 (CEST) Received: from [192.168.42.2] (worknm [192.168.42.2]) by donald.local (Postfix) with ESMTP id 12844A035B for ; Wed, 16 Apr 2025 05:20:16 +0200 (CEST) X-BeenThere: xen-users@lists.xenproject.org List-Id: Xen user discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Errors-To: xen-users-bounces@lists.xenproject.org Precedence: list Sender: "Xen-users" X-Inumbo-ID: 1806b27e-1a73-11f0-9ffb-bf95429c2676 Subject: Re: apt-get install xen-tools recursion Cc: xen-users@lists.xenproject.org References: <50901fa5-d0d6-4f82-ab17-baf30141ce84@gmail.com> From: "Manfred Haertel, DB3HM" Message-ID: Date: Wed, 16 Apr 2025 05:20:15 +0200 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0 SeaMonkey/2.53.20 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Elliott Mitchell schrieb: >> Recursive virtualization is actually supported under Xen and it works with >> some possible glitches.

"Hardware virtualization" is actually "hardware ASSISTED virtualization". Inside a VM, the processor generates traps into the hypervisor on certain instructions, so that the hypervisor can do its work. When using recursive virtualization, the virtualization instructions like VMLAUNCH, VMRESUME on the x86 generate a trap which must be handled by the hypervisor. This is how recursive virtualization works, handling these instructions. So recursive virtualization can never be indistinguishable from normal virtualization. The glitches exist mainly because recursive virtualization isn't as widely used as normal virtualization and thus it is also not as thoroughly tested as normal virtualization. Using Xen, it works quite good under the given circumstances. -- Manfred Härtel, DB3HM mailto:Manfred.Haertel@rz-online.de http://rz-home.de/mhaertel From xen-users-bounces@lists.xenproject.org Wed Apr 16 03:57:36 2025 Return-path: Envelope-to: archives@lists.xen.org Delivery-date: Wed, 16 Apr 2025 03:57:36 +0000 Received: from list by lists.xenproject.org with outflank-mailman.954863.1348787 (Exim 4.92) (envelope-from ) id 1u4ttK-0000vy-I9; Wed, 16 Apr 2025 03:56:50 +0000 X-Outflank-Mailman: Message body and most headers restored to incoming version Received: by outflank-mailman (output) from mailman id 954863.1348787; Wed, 16 Apr 2025 03:56:50 +0000 Received: from localhost ([127.0.0.1] helo=lists.xenproject.org) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4ttK-0000vr-Es; Wed, 16 Apr 2025 03:56:50 +0000 Received: by outflank-mailman (input) for mailman id 954863; Wed, 16 Apr 2025 03:56:49 +0000 Received: from se1-gles-flk1-in.inumbo.com ([94.247.172.50] helo=se1-gles-flk1.inumbo.com) by lists.xenproject.org with esmtp (Exim 4.92) (envelope-from ) id 1u4ttJ-0000vj-I8 for xen-users@lists.xenproject.org; Wed, 16 Apr 2025 03:56:49 +0000 Received: from mail-qt1-x82a.google.com (mail-qt1-x82a.google.com [2607:f8b0:4864:20::82a]) by se1-gles-flk1.inumbo.com (Halon) with ESMTPS id cf48bfe2-1a76-11f0-9ffb-bf95429c2676; Wed, 16 Apr 2025 05:56:44 +0200 (CEST) Received: by mail-qt1-x82a.google.com with SMTP id d75a77b69052e-47688ae873fso62615371cf.0 for ; Tue, 15 Apr 2025 20:56:44 -0700 (PDT) Received: from [192.168.50.240] (syn-067-243-068-214.res.spectrum.com.

In my first message should have started with something like "Welcome to the world of xen. I hope we'll be able to help you get it working in your environment." This is not because I'm any kind of a xen expert at all - much more just a hobbyist - but I have done the kind of thing you're doing several times so may have some thoughts that might help. 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.html In 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.

So, probably nothing to do with your problem. I notice that the apt-get output you supplied includes "Ign:" at the beginning of each line, meaning I think that the correct versions of those packages couldn't be found at the repositories in /etc/apt/sources.list. (https://askubuntu.com/questions/984534/updating-ubuntu-understanding-errors-thrown-by-apt) How does sources.list look? Are those repositories accessible from the machine you're trying this on?

It turns out that networking is totally kaput when using the Xen virtual bridge configuration. With that active, it turns out that I can't even ping xenproject.org. I should've tried some other network access than apt, but didn't. All my other virtual machines use static IP, so I'll probably have to figure out how to use Xen's virtual bridge on top of that. The problem isn't limited to running under VirtualBox, though. I ran into a similar problem running on my laptop, but don't remember exactly which step in the beginner's guide made it happen.

Just a suggestion, but you might try temporarily disabling NetworkManager in dom0. I found it was knocking out networking in my environment which is very similar to yours. That was some time ago but it's a pretty simple step if remember right. On 2025-04-17 2:57 p.m., Frank Eskesen wrote: > I think you've found the problem.
