virtio

For QEMU's startup parameters, QEMU uses some basic framework functions to complete the relevant parsing, which makes it easier for subsequent developers to add functionality. This part of the code is still a bit complicated, so let me summarize. An example of a QEMU-KVM startup parameter is a virtual machine created using Libvirt. /usr/libexec/qemu-kvm -name rhel6.5 -S -M pc-0.15 -enable-kvm -M 1024 -realtime Mlock=off -SMP 1,sockets=1,cores=1,threads=1 -uuid 8f338d83-41c

Original: http://www.ilanni.com/?p=6211The previous article describes how to add a hard disk to a Linux system, and this time we'll cover steps for adding Windows systems.In fact, Linux and Windows add the same method of hard disk, but also can be added through the command line and modify the configuration file.Here's how to add a hard disk by editing the virtual machine configuration file with the Virsh Edit command.Note Windows system add hard disk requires a sub-drive interface, IDE interface

course, you can also choose to use a physical CD/DVD drive or do not use any media [generally, ISO installation is used ]. 5. Switch to the "Hard Disk" tab to set the required storage space or format. If there is no special requirement, the above settings are usually selected, you only need to select the disk space you need. Format: QEMU [3], Bus/Device: VIRTIO [4] 6.
