Linux virtual machines on KVM use virtio disksSystem: centos6.6 64-bitThere are few articles on the net, how to change the disk of Linux virtual machine to use Virtio diskBecause the CENTOS6 or above system already contains the Virtio driver, there is no need to execute the following statement to load the kernel modulemodprobe virtio virtio_pci virtio_blk virtio_netmkinitrd --with virtio --with Virtio_pci --with virtio_blk --with virtio_n

Adjust the disk size of a KVM Virtual Machine By default, the hard disk images of KVM virtual machines are stored in "/var/lib/libvirt/images/". First, check whether your hard disk image format is in RAW format: Qemu-img info/var/lib/libvirt/images/Template-CentOS-6.6-32bit.img Is the result after I run the command: We can see that the hard disk image of this virtual machine is in RAW format and meets

Objective At work, we may have access to a KVM virtual machine, and many of the company's applications will run on a KVM virtual machine. Therefore, the skilled application of KVM is also one of the essential capabilities of operation dimension. So in the KVM practice, we are sure to think often about how to be more i
