Window's Instances are showing 1G NIC speed on 10G at the backend

Hello Guys,

So i have recently deployed few instances on KVM. My backend NIC's are 10G but when i deploy any instance in KVM hypvervisor. All of window's instances are now showing only 1G NIC speed.

This happened with VMware too, but it was resolved the moment i have changed NIC adaptor from E1000 to VMXnet3. So what should i need to change inside the KVM in order to achieve 10G card instead of 1G.

Regards
Vivek Kumar

You can either try changing the network interface device model to a different type, e1000 is also available in QEMU or you could try install the Windows KVM network drivers available through the iso.

Hey,
Thanks for the response. I have just checked and virtio drivers are already installed and it's still showing 1G interface instead of 10G.

here is the output of dumpxml -

<interface type='bridge'>
<mac address='02:00:32:71:00:01'/>
<source bridge='brbond0-2714'/>
<bandwidth>
<inbound average='25600' peak='25600'/>
<outbound average='25600' peak='25600'/>
</bandwidth>
<target dev='vnet8'/>
<model type='e1000'/>
<link state='up'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>

should i change to virtio in <model type > ?
