KVM : Configure SPICE Server2021/08/27 |
Configure Desktop Virtualization SPICE ( Simple Protocol for Independent Computing Environment ).
It's possible to connect to virtual machines from remote client computer. |

[1] | Edit existing virtual machine's configuration and start virtual machine with SPICE like follows. The example on this site shows to create a virtual machine without graphics, so it's OK to change settings like follows, however if you created virtual machine with graphics, Remove [<graphics>***] and [<video>***] sections in configuration file. By the way, if you'd like to use VNC instead of SPICE, replace [graphics type='spice' ***] to [graphics type='vnc' ***]. |

[3] | By the way, if you'd like to enable SPICE on initial creating of virtual machine, specify like follows. Then, it's possible to install Guest OS with SPICE that requires GUI installation like Windows without installing Desktop Environment on KVM Host computer. If you'd like to use VNC, replace [spice] word to [vnc]. |
