KVM One-click Shell automatically generates a Windows virtual machine, unattended operation scheme is divided into four steps to complete the joint;The first step: Start the startup script, so that the machine can be executed at the start of the script, to complete all the necessary basic operations (such as setting a password, binding Ip , add domain, activate), this step is repeated on a separate machine,

To facilitate the use of Virt-manager to create and manage KVM virtual machines. The default is to create a good Windows XP virtual machine, there will be no sound when connected with VNC, the sound is normal when connected with Rdesktop.Checked out some distributions of bugzilla and found a number of related bugs and found solutions on Fedora's wiki (the origina

KVM maps scsi disks to virtual machines. Note: physical machine redhat6.4, but a redhat 5.5 is installed on the Virtual machine. lsscsi cannot be used on the vm. Therefore, the vm Version 5.5 is too low, the kernel cannot be identified. Therefore, we installed a kernel version higher than redhat6.4 to confirm this problem. We found that we can see the disk and sh
