virtio drivers

Update Driver, follow the above steps to update the Virtio driver. Note 2: For the XP system Virtio-win driver version is very important, the beginning of the installation is not successful because the driver version information is not correct, if the installation process is slow is basically the driver version is not correct, change the driver test, tested, for the XPSP2/XPSP3 operating system, The

This article begins with the introduction of semi-virtualized and simulated devices, and then explores virtio

, and the I/O operations of character devices are directly accessed. To improve performance, block device I/O operations are queued and integrated. The driver's task is to process requests. The queuing and integration of requests are solved by the I/O scheduling algorithm. Therefore, the core of the block device driver is the request processing function or the "manufacturing request" function. Virtio-blk Initialization The relevant code is located at:

Virtio [edit] Paravirtualized drivers for KVM/Linux Virtio was chosen to be the main platform for Io Virtualization in KVM The idea behind it is to have a common framework for hypervisors for Io implements alization More information (although not uptodate) can be found here At the moment network/block/balloon devices are suported for KVM The

hypervisor can work together to make the simulation more efficient. The disadvantage of the semi-virtualization method is that the operating system knows that it is virtualized and must be modified before it can work. Figure 1. Device Simulation in fully virtualized and semi-virtualized Environments The hardware is constantly changing with the virtualization technology. The new processor incorporates advanced commands to make the transition from the guest operating system to the hypervisor

to replace the interface of the virtual Nic. Add hardware at the bottom, as the name suggests. next we will add Virtual Hardware: hard disk and nic. Add hardware, select "Storage", and move forward. Select "file", browse, and select the virtual hard disk file you just created. Then, select "device type" of "target", and select "virtio disk" .
