I've successfully built a Debian 9 host with Proxmox and ZFS. My understanding is that with the availability of resource sharing (e.g., "balloon" memory) it is common to overcommit resources. In other words, on a machine with 64GB, with several VMs running the same OS, I might be able to get...

I recently set up pfSense in a Proxmox VM, and while it works as an OpenVPN endpoint, it has displayed a couple of odd issues when attempting to connect from the VM to the host (ie, to the Proxmox GUI.) When the VirtIO NIC is selected, I cannot connect to the Proxmox host (though, weirdly, I can...

When creating a VM, Proxmox by default tries to put the disk image on my 'local' storage pool, which happens to be a very small SSD. I'd much rather have it default to my ZFS pool, but I haven't been able to figure this out. Any hints?

I am attempting to install a legacy Nvidia driver (version 340.102 for a Quadro FX 3800) on kernel version 4.13.4-1-pve and running into a brick wall. Installing the legacy driver per the Debian wiki produced no errors, so I ran the nvidia-xconfig utility and rebooted. However the driver did not...

I've tried various experiments to improve the audio quality in my Windows 10 VM, but this seems to have killed it. USB pass through of keyboard and mouse stopped working when I enabled this option. Well, sort of. I can still use the passed through keyboard to navigate the EFI boot menu, but once...

I have created a VM with GPU passthrough. After a lot of experimentation, I finally got it working. However, there remains one weird consequence of changing so many VM settings. When I try to boot the VM, instead of booting the virtual disk, it boots up an EFI shell. If I quit the shell, select...

I've been experimenting with PCI/PCIe passthrough this week, and actually managed to get it working. However, the fly in the ointment has been audio. USB audio was horribly garbled. Passing through the host's onboard audio works a lot better, but I still get crackling and skips in the audio when...

Most guides out there presume that you have a UEFI system that you want to use GPU passthrough. There's some discussion of BIOS GPUs, but not much discussion of what to do if you have an older PC and a newer UEFI video card. Looking on this page ( https://pve.proxmox.com/wiki/Pci_passthrough )...

I've been using Proxmox as a virtual lab to study Windows Server installation and configuration. One feature I'd like to learn and use is Hyper-V. Hyper-V does not support some features that I want, so I'm not looking to install it long term. However, unless I can figure out how to nest it in...

Please note that I'm not trying to install NVidia drivers in a guest OS, but rather the HOST OS. Somehow I got them working with kernel 4.2.8, but since upgrading to kernel 4.4/Proxmox 4.2 I've been unable to duplicate my previous success. I have a full install of Debian Jessie 8 with the...

I'm trying to create a low-budget lab for learning about server operating systems and virtual environments. I'm having to choose between two different systems I have available. One is a Core 2 Quad running at 2.2 Ghz, but without SLAT. The other is a triple core Athlon II X3 at 2.9GHz. Though it...

Fresh install of Debian Jessie (see here: http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Jessie ) with a Radeon HD 5750 as the GPU. Apparently development of the open source driver for this old graphics card has been abandoned, however there is a legacy proprietary driver (fglrx) still...

I've been trying to use VirtualBox on my laptop as a sort of mobile lab, to get some hands-on experience with server OS's. However, the laptop only has 8GB of RAM, and I found myself only able to run 2 VMs at a time. If I tried 3 or 4, I'd start hitting my swap partition. So a friend suggested...

I'm trying to set up Proxmox with Debian 8 on a laptop to create a mobile lab running a few Windows servers. I went ahead and tried to set it up on Debian 8 with these instructions: EDIT: Can't post links. Google "install proxmox on debian jessie" to get the link. However, I’ve hit a...
