    [TUTORIAL] Using mDNS inside VMs in SDN subnets

    Hello, I am a home user that just likes to play around with tech and like Proxmox a lot. I recently created an SDN and moved my VMs into it and everything works great, but I had an issue with a printer/scanner that was not getting "discovered automatically". The reason for this is that mDNS...

    [SOLVED] Ubuntu 24.04-2 template not picking up default gateway

    In the systemd manual page, seems like this is expected behavior (guess NetworkManager does not follow this as my laptop / PC works without it): I edited the option 121 in OPNSense to add the default route there and now it is picked up properly by the LXC. So turns out not a proxmox issue, but...

    [SOLVED] Ubuntu 24.04-2 template not picking up default gateway

    Apologies for the really basic question, but after setting up an LXC using ubuntu-24.04-2 template I have noticed that it is not picking up the default gateway. The only change to defaults was basically choosing DHCP instead of static for IPv4. I noticed proxmox seems to know how the distro...

    [TUTORIAL] HOWTO - Proxmox VE 8-x.x Wifi with routed configuration

    So, I have a question: why do you enable wpa_supplicant specifically for that interface? I would keep it disabled and use just `/etc/network/interfaces` to control everything. For example: allow-hotplug wlp6s0 iface wlp6s0 inet static address 192.168.5.10/24 gateway 192.168.5.1...

    [SOLVED] The serial number can't be longer than 20 characters

    I anyone comes across this, apparently there is now a limit to the number of characters to the serial number.

    Why is one-to-many USB device attachment possible?

    I have 2 VMs in my Proxmox: one has GPU passthrough for my main Linux desktop. The other is a Windows VM which I use for work (accessing my employer). I generally remote-desktop from Linux into the Windows VM with Remmina (it works great because it's basically a "localhost" connection) during...

    Migrate VM to laptop with QEMU/KVM

    So, luckily I had remote desktop enabled, therefore I was able to RDP into the VM running on my laptop. Once logged in, I reinstalled the full VirtIO driver suite from the ISO. This ended up fixing the problem and I was able to log in from the virt-manager UI after rebooting.

    Migrate VM to laptop with QEMU/KVM

    Hello, I am a hobbyist using Proxmox on my main system. My desktop is a VM with GPU passthrough. I also have other VMs and one of them is a small (ram/disk) Windows 11 machine. I need to transfer this machine to my laptop which runs Fedora and only has VirtManager. To that end, I followed...

    I/O performance for heavy workload

    So far this has not been an issue at all. The problem only exhibits during prolonged writing to disk. I mentioned Steam downloading as an example, but if I am not actually downloading while gaming (and you can disable updates while gaming) then there is no issue.

    I/O performance for heavy workload

    I know exactly what you mean. The pain my laptop still gives me to this day is terrible (I have the Nvidia disabled right now due to instability in 6.9.x kernels). I will look into this more. If the driver is not in the kernel OSS codebase I could get some other controller that has the same...

    I/O performance for heavy workload

    I am thinking of using an external SAS enclosure, something like this: https://www.highpoint-tech.com/product-page/rocketstor-6434ts Since the controller is a PCI card, does the connection to the box reduce the performance or is it equally fast? My plan is to add the PCI card, then purchase...
