I have that option set as well and cpu=Haswell, but this messages still appear. You can stop this error message to appear by lowering your kernel log level: echo 2 >/proc/sys/kernel/printk

Any progress here? Should not be too hard to increase it?

Wow, thank you verry much, there must have been a bug in the past, cause I always had the x-vga=on option, but got the NVidia Error 43 with it, then I always added my mentioned args line. No shutdown/start hang atm. Seems to be working now. Makes me happy :D Regards

The sound problem is a KVM or specially VFIO Problem with interrupts, for some devices your mentioned MSI Trick helps, this problem is known for a long time, but no real progress, just some workarounds (which did not help me, so I forgot them, sry). What always helps is buying a dedicated sound...

So I created a bug report, if I did miss something feel free to add comments. https://bugzilla.proxmox.com/show_bug.cgi?id=1201

I do not understand you clearly, you mean I should send a mail to the bug assignees? So even in debug installation it is not possible to set the correct zfs blocksize?

Hi, how can I set a different sector size for zfs on proxmox installation? As I read somewhere it's always set to ashift=12 aka 4k blocksize. I want to set it to 8k (ashift=13) and on another node to 32k (ashift=15?).

Hi, I noticed that while there is heavy load on file transmitions on zfs (like restoring a VM) the ksm process is slowing down the whole system heavily. I reserved 35GB RAM for zfs, and forsure it's the task of ksm to scan the memory pages, but it should not scan the zfs mem-cache-pages. Any...

Btw there is no need for a tutorial for building a git and copy a file.

There is no picture file, its in the seabios/ovmf "file". As I said, download the git and build. But sorry, just trying to help (that was sarcastic)

You can build qemu (or just seabios/ovmf) by yourself and replace seabios and ovmf files with yours, then you got rid of the logo. But why you want to do this?

Passthrough of primary VGA is not supported, maybe this will work in future like they implemented passing through Intel igp.

Have not much tested yet, but what I can say till now is that in the mainline kernels 4.6/4.7/4.8 and in the YakketyYak kernel 4.8.0-22-generic the zfs and vfio modules are missing and forsure the pcie_acs_override patches and some other stuff, so I'm going to try my own kernel build with the...

Ok, thx, I'll try and share my experience with it. Forsure this is not a productive system, it's just a test environment.

So in pve-test there is a pve-qemu-kvm 2.7 package now, thx for that! What I try to do needs at least kernel4.6, so before I screw up my whole pve-test system, I'd like to know if there would be problems by installing newer kernel from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ As I...

So my question when there will be a pve-qemu-kvm-2.7 build released is still not answered. Will there be a build for proxmox4.3 or will it not be released until proxmox4.4 ?

You misunderstood me, pci(-e) passthrough with gpu passthrough is working for years now (and like a charm). You need to wait for 2.7 only for the Intel iGPUs, but this may need some extra work to be done for the configuration, just try a normal dedicated GPU step by step from the wiki, it's...

Not to impressive ;) Just follow the steps here https://pve.proxmox.com/wiki/Pci_passthrough It was kinda complex some time ago, but now almost everything works out of the box in proxmox, just waiting for qemu 2.7 for the iGPU passthrough so I can remove one GPU from my host.

I passthroughed a lot of Devices, nVidia GTX970, nV GT430, AMD HD6950, AMD R9 290X, SAS RAID Controller, PCI Soundcard, USB Soundcard, USB Controller, PCI/PCI-E TV Cards Until qemu-kvm2.7 you could not passthrough an Intel Integrated Graphic, but it should work now. No need for a Quadro Card.

I'm asking cause in your wiki qemu 2.7 is mentioned, so there should be a build or am I wrong? Here under CPU Hotplug: https://pve.proxmox.com/wiki/Hotplug_(qemu_disk,nic,cpu,memory)
