Proxmox Thread - Home Lab / Virtualization

I wont go into a point by point response this time because

A) you are drawing a lot of assumptions about me which arent necessarily true (e.g. the original assumption on basing my observations with a display/displays incapable of handling proper HDR)
because thats what you gave out as examples? what do you think a layperson would assume when you say there aint much difference between HDR and HDR10/DV and I play HDR content on my HDR800 device?
This time around you have assumed that I have tested only with ATV/ not tested remuxes / not tested physical disks
And also assumed (probably) usage of a non ATMOS setup
And also assumed I am comparing remuxes with 15mbps streams (when I had clearly stated 40)
you didnt? you just said and I'll quote, "my personal take is that anything over 40mbps /hevc main10 /DV or HDR10+ gets visually indistinguishable from a physical disk.", and btw which stream have you seen with a 40mbps bitrate? On the peril of making another assumption and correcting what I said in my previous post, 40mbps is the max advertised bitrate on ATV+, and in general it can go anywhere from 15-25/26 mbps for a 4k movie but yeah sure you'll get a 40mbps stream on ATV+, the only streaming service that offers these kinds of bitrates is Sony's Bravia Core or BCore, around 80mbps and that too doest not have much content in that bitrate, and while we are at it, lets move off of bitrate comparisons, bitrates are not a good comparison for different rips, its a very rough and largely inaccurate comparison depending on quite a few assumptions to work. I shouldnt have brought it up in the first place, I think thats where this convo derailed.
On a side note, I may not have super discerning eyes but the color variation on the links you sent are so stark that even a non video enthusiast would notice that instantly during actual playback.
Which is why I mentioned earlier as well that rather than believing a post from a random unknown tester on the interwebs (e.g. the page you linked to) or Youtube, I would rather trust my own tests, equipment, configuration and eyes (or take inputs from someone i know).

There is no means for me to know if the setup tested by this unknown individual (from your links) were configured or tested correctly which i strongly believe is not the case here
(for instance the ATV frame in the general comparison is almost comically bad/blurry/low res - either intentionally or due to lack of attention to detail by the tester)
did you perchance go through the other images? on peril of another assumption, I'm gonna assume you are talking about the first pic in the links I sent which just show the color space and not the actual image, if you would go through the other images in the set you would have seen "fairer" comps, but yeah my bad, I was too lazy to go digging around forums in trackers to get other comparisons which are mapped on a frame to frame basis.
BTW FWIW the shield is not capable of handling profile 7 as intended - it processes only the base layer. In fact as things stand, even the cheap firestick 4K is arguably the better media player of the 2 than the now hopelessly outdated shield (and before you assume again, Yes, I have used a shield, )
never said Shield is the best? I said its better than the other devices listed like the firetv stick etc etc, the main USP of shield is that it has Atmos Bitstreaming support, almost all players except for Blu ray ones have trouble actually playing Atmos, either the atmos is ignored or its transcoded, Shield and Shield TV Pro have the best support for Atmos outside of traditional Blu-Ray players or something like a Zidoo but then you need to hack around Zidoo's incompatibility with Plex/Jellyfin (not sure if they got their shit together now, its been a while since I looked into Zidoo)
B) We (and I am equally guilty) are digressing massively from the core thread topic - If you do want to pursue this discussion further, happy to continue on a separate thread
Finally something we can agree on, I did derail this thread quite a lot, but yeah, feel free to create another thread and I'll give you all the comps you want once I get around to digging up old threads in my forums and getting those comps
 
Tangentially related to the thread title, I recently discovered the awesomeness that is POE!

Any simple POE switch paired with inexpensive 48V to 12V converters sends 12VDC to anywhere where a ethernet cable reaches, perfect for far off installations of ESP8266 modules/sensors and basic wifi access points, ha. Power cycling can be easily done through a smart plug for the POE switch. Ethernet is limited 100mbps though, not sure how to get around that but it's okay for now since all of the access points I have in use (7!) are 100mbit anyway.


I don't need to run AC wiring to the extremes of the house anymore, which is probably the biggest plus point.
 
Not an expert, but Proxmox Backup Server is usually the recommendation I see for this. It is also fairly easy to setup and you can automate it to do it every X days.

In my case, I do it the manual/stupid way. I turn off the server, plug in a liveusb, boot into a linux distro that supports zfs out of the box like CachyOS, then I use dd to clone the drive. I do this once a week. The advantage of this is that if the server ever fails, I can get back running with a single dd command.
My server's 7+ years old boot SSD started failing so I had the opportunity to test this dd backup solution. Long story short, it kind of works but probably don't do it.

In my case, the server refused to boot up after recovering the disk image to a new drive. I eventually discovered the reason after a few hours of troubleshooting. It was because the new drive is NVME (while the failed one was SATA), and adding it changed the address of devices on the PCI bus, which meant that the GPU passthrough which was hardcoded to a particular address stopped working. There may have been some other steps required to get it to boot too, like regenerating grub, but I'm not sure if that was really necessary. In any case, it wasn't nearly as easy as I thought.

As others have said, it's far easier to just use the builtin scheduled backups that proxmox has (Web GUI > Datacenter > Backup > Add) and back it up to a different drive/NAS or use Proxmox Backup Server from another server because that comes with deduplication support i.e incremental backups only take up additional space when a file changes. It's true that you don't get to backup the host OS with either of those but that's fine. It's simpler to reinstall Proxmox + restore backed up VMs/CTs than recovering the entire system from a disk image.
 
Something I've been meaning to do is to backup the bash shell command history since I usually forget how I configured something when it comes time to restore/reset.

A daily cron job that uploads the current history as a datestamped file to a local FTP server is what I'm thinking of. Then a daily cron job on the FTP server to delete all but keep the last 30 days of files plus one from each month. I have something similar setup for other backups:

1 0 * * * /usr/bin/find /root/backups -type f -mtime +30 ! -name '*01-*' -exec /bin/rm {} \;

The backups are named as YYYYMMDD-hostname, so all of the daily backups older than 30 days are deleted, except the ones done on the 1st of the month.
 
I have a setup in mind. Please enlighten if there is a better way to do it or if I am missing something.

I have a P330 Tiny with 3 NICs (1x built in + 2 in the PCIe card).

I was running opnsense standalone, but would like to virtualize it.

I was thinking about proxmox + opnsense.

Opnsense would be firewall + router + DHCP server for my setup.

Can I use Dual WAN + LAN while having only 3 physical ports? I am new to proxmox, have never used it.
 
Same pinch @napstersquest. I am trying a similar setup on one of my proxmox node. That node has 3x 2.5 gbps (2 onboard + external) NICs, out of which one is connected to the switch. While the remaining two will be put to use for OPNsense VM. Haven't got around to setting up OPNSense yet, and I hope to start it by the coming weekend. :D

If I understand this correctly, yes.

You can passthrough both WAN ports to the VM and create a bridge with the remaining port, that bridge will handle both proxmox traffic for the host and network traffic to the VM.

Effectively, the bridge becomes a three port switch: one port (virtual) to the VM, one port to proxmox (also virtual) and one port back out to your network (the actual physical port).

The bridge will need to be created after proxmox is setup and you're logged in, but before you make the VM. You'll need to remove the IP configuration from the physical port and create a bridge with the same IP configuration with the physical port specified as a 'bridge port'. Both changes need to be applied simultaneously so that you don't lose access through the webui. This assumes you have a router with a gateway configured somewhere in your network and the proxmox machine is connected to it.

i have it running this way for many years now.. first pfsense and then opnsense
2 physical ports would be needed for your 2 X wan
the 3rd port goes to your physical lan switch.

All VMs (including opnsense) will be linked to this 3rd (primary) port over a virtual bridge (think of promox primary port as connected to a physical switch with all the VMs / containers on proxmox conected to it) and this 3rd port then hooks up physically to the rest of your LAN
