![]() ![]() You have 4 different Networks ID's there. I wonder which IP address I should fire up on Windows guest ? I have 6 Windows 10 guests created on KVM, all having same problem. Those pesky wires and switches have to slow everything down. I have a GigE network with nearly 100% Intel NICs, so from a VM on one KVM host to a different system, I get Of course, going across a real wire will be limited to whatever the network can support. ![]() Similar speeds happen between different guests on the same host-KVM server with the virtIO NIC drivers.Ģ0Gbps isn't bad for next to zero effort, right? It also is helpful if inside the guest VM, that you use a virtio NIC driver and inside the VM, there is a virtio NIC driver.ĭoing this, I get fairly great connection speeds between the guest and the host: Then when you setup each VM, make certain the setting for the Network uses the bridge device that you made up, not any of the virbrX junk. There are a few threads in these forums about netplan + KVM + bridges too. has a section on setting up a bridge on a host machine. What's the point of a system that can't be seen by other systems? Non-networked games? I find little use for any of the virbrX stuff. If your VMhost has an IP of 192.168.1.164/24, then all your guest machines would use that subnet too, if you configured a bridge correctly. No difference at all.Įverything I've posted works with bridged VMs or physical hosts. My LAN DNS knows about each VM, just like it knows about every physical computer. I only use NAT or host-only for systems that won't communicate with any other system (real or VMs). If the windows guests are connected to a host bridge, then use them just like physical hosts on the same DHCP/static subnet as the host machine and forget they are VMs.Ĭonnections between VMs and other systems of any sort work just like they were physical machines if you use the linux bridge setup.
