    Nested Hyper-V (Windows 10) with KVM?

    Hi, Been debugging why my Windows 10 machine (VM) is so darn slow. Found this, and it solved the issue. So far so good - until I tried to run a VM in Hyper-V on that same Windows 10 guest. Turns out you need to use host and not any of the other CPU types. It was absolutely flying on...

    [SOLVED] How can I specifiy a nominal speed of a kvm virtio NIC?

    Good morning, while expanding monitoring of my PVE systems I am stumbling over a (for me) problematic detail: the reported speed of a virtual NIC is always "10", which means 10 MBit/s. Specifically the host tells me this for any VM: root@pm1:~# cat /sys/class/net/tap110i0/speed 10 Just for...

    Hi, we want to use Barrier KVM to control multiple VMs from one PC without having to fiddle around with hardware KVM switches. Installing the distribution Barrier packages on CLI systems makes no sense as the dependencies will install all the X11 stuff. QEMU has an integrated Barrier client...
