Kvm Virtio Drivers

Network driver First, shut down the guest and then edit its configuration file: virsh edit guestname In the section, add a virtio model, like this: ...

  • Installing the KVM Windows virtio Drivers10.2.
  • Virtio drivers are KVM's paravirtualized device drivers, available for Windows guest virtual machines running on KVM hosts.
  • Another option is use HPET/RTC and -clock= qemu option.
  • Installing the Drivers on an Installed Windows Guest Virtual Machine10.3.
  • Installing the KVM Windows virtio Drivers10.2.

Using KVM virtio Drivers for New Devices Paravirtualized drivers enhance the performance of guests, decreasing guest I/O latency and increasing throughput to near bare-metal levels. If you are confused, the libvirt Networking Handbook provides a good outline. Warning: User networking does not support a number of networking features like ICMP.

These drivers are included in the virtio package.

It is less confusing, it is faster (because it's always 1:1 pair), and it supports more parameters than old -net..-net way.
