  • I’m familiar with Proxmox, virtualbox, and KVM/KVM manager.

    If I want to set up a PC to virtualize multiple operating systems, but with the feel of a multiboot system, what virtualization software would you suggest?

    My goal is for the closest I can get to a multiboot system (windows, Debian, fedora) but virtualized so I can make snapshots. It should feel like I’m on baremetal when inside the VM.

    Virtualbox is clunky with lots of pesky UI cluttering the screen and Proxmox doesn’t seem great for this use case.











  • Thanks. That helped a lot. It gave me a good basis for some further googling.

    It ended up that the Internal Clock of the hardware interface was deselected in alsamixer. Enabling it fixed the no audio issue.

    For the channel remapping I tried a bunch of different config files until finally one actually managed to not be ignored. It’s absurd how many separate configuration files and sound settings menus exist for linux audio and there’s no guarantee the one your editing is even being used. An absolute mess IMO and it’s no wonder people shy away from linux for desktop purposes.

    Funny enough, despite getting the channel remapping to work, it’s completely ignored unless you put pulseaudio -k into your user profile. And even now, because the remapped output device doesn’t show up on boot, it has to be manually set to the default output every login.

    At least I have the right channels mapped though.

    I love linux but god damn is it a hot mess for the simple stuff.



  • Due to my understanding of it, I was hesitant to use AC recovery in the case that the power goes down more than once in a short period. It could drain the UPS to the point that it might not be able to sustain enough runtime for a proper shutdown. But I’m also a bit confused about the setup here. If the server is sent a signal to shutdown due to a grid outage, who is telling it the grid was restored? The server would always detect power because of the battery backup, so I don’t think AC Power Recovery would work in this case, no? I believe I have the UPS comm server (probably apcupsd) installed on the server itself, so there’s no way for it to know to wake up unless from an outside source.

    Maybe you have some further incite into how to make that setup work properly.

    I’m brainstorming here, but would it be possible/feasible to have the Unifi Dream Machine execute a script everytime it turns on telling the server idrac to power up. I’d have to see if the UDM has that ability as well. The UDM turning on would only really happen if power was restored from an outage. Otherwise I could send a command manually once I have access to the network.






  • I’ve had the IP for a couple of years so I can rule that out. The only thing different than usual is I recently added a backup server to the VPS network. I’ve been doing a remote backup from one server through the VPS to the backup server over the past week. It’s a 4TB backup averaging 4MBps.

    My guess is that the VPS provider’s algorithm is bungling the bandwidth calculations, possibly refreshing the bandwidth amount incorrectly which to the black hole detector appears as a sudden spike in bandwidth rather than a steady flow.

    I’m going to keep running the backup and compare how long after the backup starts that I get a black hole trigger. If it’s relatively consistent then that might be the problem.









  • I’m curious if anybody has a more “self-hosted” solution, but I use burner numbers through the MySudo app and simply delete the number and buy a new one every few months.

    If you look up Michael Bazell, he has a strategy for bulk buying voip numbers by tricking voip providers into believing you’re a large established business. You could buy dozens of numbers and just cycle through them. But that method requires a lot of work and social engineering and the providers are becoming privy to those tactics.
