The initrd.img and vmlinuz shown in the filelist below are the tools for this included on the first CD in the set. ------------------ locate netboot boot files ----------- tlvie...@ga-p45:~> sudo mount /data2/kvm/CentOS-5.5-i386-bin-1of7.iso /mnt/iso -o loop tlvie...@ga-p45:~> ls -al /mnt/iso/images/xen/ total 9573 drwxr-xr-x 2 root root 2048 2010-04-29 17:29 . drwxr-xr-x 4 root root 2048 2010-04-29 17:29 .. -rw-r--r-- 2 root root 7552658 2010-04-29 17:23 initrd.img -r--r--r-- 1 root root 441 2010-04-29 17:33 TRANS.TBL -rw-r--r-- 2 root root 2244980 2010-04-29 17:23 vmlinuz ------------------ snip ----------- copy the above 2 to a local dir #cat cent55.py ------------------- cent55.py --------- kernel = 'vmlinuz' ramdisk = 'initrd.img' name = "cent55" uuid = "442db20d-7a82-409b-b8aa-a352c1fe127c" maxmem = 512 memory = 512 vcpus = 2 #bootloader = "/usr/bin/pygrub" #bootargs = "-q" on_poweroff = "destroy" on_reboot = "restart" on_crash = "destroy" vfb = [ "type=vnc,vncunused=1,keymap=en-us" ] disk = [ "phy:/dev/maxvm/cent55,xvda,w" ] vif = [ "bridge=br0" ] extra = " install=http://mirrors.kernel.org/centos/5.5/os/i386/ console=tty0 console=ttyS0,38400n8 console=xvc0" ----------------- unsnip -------------- #xm create -c cent55.py this will start an http PV install. AFAIK the boot files are netboot only and won't allow access to your CD as ISO or otherwise. Before firstboot, comment out the kernel/ramdisk lines and uncomment the 2 pygrub lines. -- Mark _______________________________________________ CentOS-virt mailing list [email protected] http://lists.centos.org/mailman/listinfo/centos-virt
