In Centos6.3, do not upgrade the Kernel. It is best to align it with the version on the kvm network. · 2.6.20 kvm-12 · 2.6.21 kvm-17 · 2.6.22 kvm-22 · your kernel has to be 2.6.29 or newer to run any version of qemu-kvm (kernel 2.6.27/2.6.28 with kvm-kmod 2.6.29 will also work) www.2cto.com
It will be used after installation. At this time, the graphical advantages will come, of course, for newcomers. Vncyum install tigervnc-server-yyum install fontforge-yyum groupinstall Desktop-y requires a password when it is started for the first time. The password is saved in/root/. vnc/passwd.
Modify the xstartup file and add gnome-session & Shift + g to the last twm & delete file. Modify the/etc/sysconfig/vncservers file vim/etc/sysconfig/vncserversVNCSERVERS = "2: root"

VNCSERVERARGS [2] = "-geometry 1280x800": configure the firewall and allow the port number of 5900 + 2 (desktop number) to use the vnc Remote Server www.2cto.com service iptables restarta. in linux, run the vncviewer command. The format of the server address is 192.168.3.119: 1.
B. In windows, run vncviewer of windows. Its usage is similar to that in linux.

C. Use a browser (platform-independent) as a java applet to start the program in the form of http: // 192.168.3.119: 5801 (The vnc port starts from 5800 and so on, usually 5800,5900) to start kvm www.2cto.com

Network Configuration for kvm Virtual Machine Network: a) Virtual Network 'default': NAT (default mode, supports Virtual Machine Internet access but does not support mutual access) B) host device vnet0 (depending on the effort): macvtap (supporting mutual access) c) host device vent0 (bridging 'br0') (bridge mode, you can use virtual machines to become hosts with independent IP addresses in the network.) www.2cto.com
