I think we fixed this in the 3.1.1 point-release isos, but you still may hit it on an upgrade. fsmithred ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Do I understand correctly, that having configuration variant with QEMU /X11/vnc is required, since desktop guests configurations will be supported? My setup is headless and lean, pretty plain. There are several things I do not have - network and cpu load balancing, cpu numa node affinity, back up tooling and strategy and apparmor + logging + safety/firewall. I believe that these things are essential part of a toolkit for bare metal hypervisor, plus administration scripts or webUI (nginx + lua?) + apt. The only good thing I have is that my set up is running from packages out of box, which should be good for maintainers, i guess. I more or less familiar with scripting for libvirt and back up, but no meta-scripting for installation, packaging and deploying. I can do lua, php, perl, nginx, apache, c, make, SQL, JS, HTML, etc. Cheers, Andrzej -- AP ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

It's not my intent to bash systemd but it's worth mentioning that I've had many other issues with Debian based hypervisors over the past few years (50+ VMs across several hypervisors) that involve systemd when reviewing logs post-mortem. Hypervisors will sometimes not reboot. Even when trying to un-stick with Magic SysRq. The console will just show systemd errors instead. Likewise, when systems do reboot, sometimes they inexplicably stop booting and need to have the power button hit. Another time, OpenSSH would not work due to /var/run/sshd missing during boot. Another issue involved systemd and a LUKS encrypted partition. Another time was missing LVM devices. This happens across systems of varying age so hardware issues are kind of ruled out. The issues keep getting more frequent and odd as months go by. It's like these systems have regressed to what L > inux was in 1995. > > I would strongly suggest running your virtualization on Devuan.

I did not took a challenge and migrated to DEVUAN. May be worth mentioning, that in my setup I use three virtual disks for one guest, which is not well supported by current apparmor configuration, so I took a shortcut: I switch the apparmour off (disable) during snapshots create/commit for back up script. Sure I better learn about the apparmor configuration, but not this time. Cheers Andrzej ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

I did it because I needed to if I wanted the bits "I needed" from libvirt on a Debian version that was pre-jessie. I still built with dbus, I just had to also build the right version of dbus. If I was starting from scratch now, I'd install Devuan Beowulf and apt-get install libvirt. I don't get hung up on dependencies and I'm too lazy to want to expunge dbus just because I don't understand it and I'm paranoid (I do and I'm not). I'm still running my self-compiled libvirt because I've progressively upgraded from Debian Wheezy (which is what I compiled it on) to Devuan Jessie->Ascii->Beowulf and it hasn't broken. Because it hasn't broken, I haven't fixed it. It still lives (with all its dependencies) in /usr/local/libvirt.
