    Intel IGD GPU Passthru Possible ?

    Hello, i run a Dedicated Server with a Intel i7 4770 CPU. That machine is running Proxmox 4.4 with 4 Windows Server 2012 VMs. Is it possible to share the IGD from the CPU on all 4 VMs at the same time ? If so maybe someone can point me in the right direction. Thank you very much

    Hi Proxmox, Is there a way to pass through the "aes" instruction to Guest VM by using CPU model kvm64? I noticed with recent PVE 5.1-35 we could enable the PCID flag on the CPU model from GUI. Would be nice to have AES flag as well. I know using CPU model host will give all the new CPU...

    "CPU limit" should be set rather than "Cores" when creating CTs

    The default CT creation dialog offers us to set number of CPU cores, but not CPU limit. However that causes CT to be locked on specific cores preventing it to use other cores under load, which might result in load spikes when two or several CTs get loaded on the same core. It somewhat tries to...
