[ch huang <justlooks@xxxxxxxxx>]

hi,all
i also checked ,my cpu is support the full virtual mode ,when i add -p option ,it's ok.i do not know why?


virt-install -n SN244_Test_Test44 -r 8192 --vcpus=16 -f /dev/vg01/44root -f /dev/vg01/44swap -f /dev/vg01/44var -f /dev/vg01/44data -m 00:16:3e:61:63:63 -b xenbr0 --nographics --accelerate --os-type=linux -l http://172.16.2.45/64/5.3 -x "ks=http://172.16.1.111/myinstall/new/newd1.ks.cfg"

Would you like a fully virtualized guest (yes or no)?  This will allow you to run unmodified operating systems. yes

Welcome to CentOS                                        

and ,here is the log output,i think the reason is xen can not find the /dev/None,but i do not understand when i use -p option,it's ok?
