Hi, I have just done a clean install of FC6 with visualization on a single cpu box (AMD 1.7+XP 1.5G ram) The performance of the box running FC6 is fine, all the windows and menus open quickly and smoothly. I followed the FedoraXenQuickstartFC6 and all seems to work perfectly except the guest seems to run very slowly. The Virtual machine manager shows about 0.1% cpu use for the new guest and Domain-0 stays about 4% I have extracted the FC6 isos onto the same box and created a nfs mount point for the source. I am using /var/lib/xen/images/testOne as the directory for the disk path with a 3G limit I set 512Mb ram and 1CPU The boot seems quite quick, and anaconda starts, all the selection of the language and keyboard seems ok too. Then it sits for about 15mins with Running Anaconda at the bottom of the screen, then starts the x window. It takes about 1/2 hr for a X cursor to appear, that will follow mouse movement, but takes a couple of seconds to catch up. I never have seen anything more. Just a black window, even after leaving it all weekend. when i run virsh list it always says the testOne domain is blocked. I have looked in all the log files and the console, but there are no errors. Anyone got any ideas? as i guess its not meant to be this slow.
