    Proxmox Root session down, OS is down but hardware is still running

    What VM's do you run? If you have a bunch of Debian or Ubuntu VM's or CT's they will also kick off their cron.hourly at the same time as the host. Perhaps your system can't handle the load or the power supply is too weak or something like that. Seems more likely than Claude's "idea". You do...

    One node in a cluster of 3 constantly restarting every ~2-5 minutes

    This looks like it has something to do with power management. ETA: Yeah, intel_runtime_resume() is in i915_drv.c and seems to be the handler for resuming the display from suspend. Is there perhaps a setting in the BIOS to tell it there is no display? Another thing to look at would be any sleep...

    Trouble with configuring network

    The screenshots look fine to me. Since you are running under another hypervisor, it could perhaps be a setting on that hypervisor rather than in PVE. Desktop hypervisors often restrict network access in various ways by default, such as only allowing access to/from the host they are running on...

    Proxmox Root session down, OS is down but hardware is still running

    Have you reviewed your cron jobs? Perhaps you ran a script that installed one and you forgot about it. Places to look are /etc/cron.* and "crontab -l"

    Backup notifications only on error

    Mail providers have to accept plain SMTP on port 25. That's how mail gets transferred between providers. Most, however, only allow such mail to be delivered locally, not forwarded, in order to prevent abuse by spammers. Mail that must be forwarded needs to be submitted on port 465 or 587 with...

    Shared Remote ZFS Storage

    Oh, look, another "new member" stops by to tell a 20-year-old project how to do things.

    Any guest OS support matrix on Proxmox?

    DOS doesn't multi-task so it would have to be a terminate-and-stay-resident program. Might be a bigger change than one would think. Plus there's no demand .

    [SOLVED] OK to use nVidia GTX 1660 for PVE 8.3 ?

    Not really. If that is your only use case the nouveau driver should be fine. I would get something else if you have not purchased it yet is all.

    [SOLVED] OK to use nVidia GTX 1660 for PVE 8.3 ?

    NVidia is problematic because their drivers are proprietary and aren't included in most Linux distributions. They have to be compiled for the kernel you have and they tend to lag behind the latest kernels (see the many threads here about problems with NVidia and upgrades). There is a free driver...

    [SOLVED] No VM or CT can startup

    Maybe if you posted your network config someone could. ETA: The pastebin errors mention OVS, which is not the standard setup. So people will need more info than "it doesn't work".

    Debian LXC web service No external access

    If you have a "home" account and the web service runs on the standard ports of 80 & 443 it is very likely that your ISP is blocking it. Terms of service usually say "no servers" and that is often enforced with technical means. If this is a "business" account or is hosted at a commercial...

    LXC - An NVIDIA kernel module 'nvidia-drm' appears to already be loaded in your kernel

    Um, you can't install modules from inside a container. ETA: Reason is that containers use the host's kernel. It would be a big security problem to allow containers to modify the host kernel. You must install any drivers/modules from the host side. Or use a VM, which has its own kernel.

    Host got no IP, VM is available

    Think about the security implications of what you are asking.

    qm remote-migrate slow over WAN

    More data would be helpful. Have you tested the connection with iperf? You may have fast connections but with 48 ms of delay there are a lot of things in-between the sites.

    How to install second HomeAssistant VM for testing under Proxmox - with Backup of the first VM ?

    You at least will need to change the MAC address of the second copy of the VM. It is under Hardware > Network. If your DHCP server also enters the client name into DNS you will also need to change the hostname inside the second VM (hostname command, possibly edit /etc/hosts).

    Windows VM RAM usage

    That "unused" cache memory has to come from somewhere!

    Cannot update windows 11 to 24H2 - CPU not supported

    Qemu does not emulate features that don't exist in the underlying CPU. If your CPU isn't W11 compatible there is no way to fake it afaik.

    Incorrect RAIDz2 "Free" space reading in the dashboard

    You do know that ChatGPT doesn't "know" anything about anything, right? It should not be trusted for any purpose without verification. Using it as a learning resource is like having a teacher who sometimes lies for no reason.
