Philip Rhoades wrotes : I want to test out a bunch of LiveCD distributions - is it possible to set these up as guests under Xen so I don''t have to shut down my main machine? I did that with virt-install : Suppose you have a iso image of the cdrom and the Virtual Technology in the processor on recent computer : on line 4 you can write what you want even the disk path of another VM so you can tune the it''s file system on line 8 where is your iso image (don''t need burn a cd) [root@baudelaire ~]# virt-install 1 Would you like a fully virtualized guest (yes or no)? This will allow you to run unmodified operating systems. yes 2 What is the name of your virtual machine? knoppix 3 How much RAM should be allocated (in megabytes)? 400 4 What would you like to use as the disk (file path)? /virtualMachines/knoppix.img 5 Disk /virtualMachines/knoppix.img is already in use by another guest! 6 Do you really want to use the disk (yes or no)? yes 7 Would you like to enable graphics support? (yes or no) yes 8 What is the virtual CD image, CD device or install location? /home/KNOPPIX_V5.1.1CD-2007-01-04-EN.iso Starting install... libvir: Xen Daemon erreur : opération GET échouée : xend_get: error from xen daemon: libvir: Xen Daemon erreur : opération GET échouée : xend_get: error from xen daemon: Creating domain... | 0 B 00:08 libGL error: open DRM failed (Opération non permise) libGL error: reverting to (slow) indirect rendering the Vm start in a new window
