![]() ![]() SCSI is probably not under PCI and the video is not either.ĮDIT: Even the mouse is laggy, when not dragging windows or doing anything other than moving the pointer around. I will google on PCI passthrough but this seems mostly to be for NICs or controllers. Man, no matter the setting I change there is no improvement, it's as if something else global is so slow that any config change does not affect performance enough to make it slower than that global slowdown thing. The processing then seems to be ok, I believe. So the VM without DE is 3.4% and 17.6% slower than the host, which I believe is fine? Then I booted with Level 3 directly to CLI inside a Linux VM and downloaded that SAME iso file from the same place on the web (it's the Linux distro ISO itself) and timed the following:.I went in Proxmox Shell and timed the following:.The above don't change performance at all.I normally use SPICE and it's virutally exactly as slow as VNC and RDP, to the eyes.I won't spare anything until I find what's going on here. I can do all that today, except PCI passthrough if I can't find a short tutorial quickly but it'll come on that one too. That will rule out the hardware issues, I believe. I will also try to install Linux on the physical machine (instead of Proxmox), install Virt-Manager and install 1 Windows and 1 Linux guests to see how it performs. I will try another distro to make sure as the one I tried heavily uses blur and transparency. Yes Linux is also slow and is even a little slower than Windows, which doesn't make sense to me. But ANY thing I can try is worth trying at this point. No harm on testing PCI passthrough enabled though, I need to find how to do that first. Not sure if it's PCI passthrough related, cuz even typing anything in any app within the VM has a 1-2sec delay before the last character typed displays on screen. I've read 16 should be enough but in this case extremes might provide clues on what's wrong with my setup. I went up to 128megs on video but I can easily give it 512 why not, I'll try that. Yes I have tried cpu host (seems a very little slower) as well as few cashing methods, none, writeback, writeback unsafe, direct and another one. Sometimes it's better to identify the issue first, but sometimes it's better to try out various things until one works. The processing seems quick, I was able to see the verbose update process in an Arch-based Linux distro and it was processing faster than it could display the lines.ĭoes anyone know what I could try to fix this? Last info: when I type say in the command line of a VM, it lags before the characters display. Since it's slow also with Linux VMs, something tells me it's either a major config setting my eyes are unable to see after 20 hours looking for, or the host machine hardware is not intended to work well with Proxmox-type hypervisors and I made a bad choice. I bought this machine specifically to use Proxmox on it. CPU type, NUMA, Ballooning, Display, Machine, Controllers, Bus Device, Cache, RAM amount, CPU cores amount and even some CPU flags, but that went bad so I left all to default.Īlso slow when using RDP to the VM, but it seems a little bit faster and I mean "a little". I have tried a lot of settings as I said. There is no Warning notification in the Device Manager. I have the QXL installed and all VirtIO drivers as I have asked the installer software to install all of them.

I spent close to 20 hours trying countless settings, driver installs, etc. Dragging windows is slow, hovering over a dock with icons is slow, opening file managers display slowly, etc. The performance is comparable than what it was on my Proxmox test machine (10yo 2-core Laptop!). It's even worse on Linux, which is weird. I am having quite slow performance on both Windows and Linux VMs.
