| | 1 | = Upgrading Xen machine from etch to lenny = |
| | 2 | |
| | 3 | This is hairy, so be prepared. Upgrading the domU's to lenny is not a problem and should be done first. When you are ready to upgrade the dom0: |
| | 4 | |
| | 5 | On each domU: |
| | 6 | |
| | 7 | * make sure udev is installed and install the most recent linux xen modules (you should only need the xen modules if you are doing something like decrypting a volume in your domU) |
| | 8 | {{{ |
| | 9 | aptitude install udev linux-modules-2.6.26-2-xen-686 |
| | 10 | }}} |
| | 11 | * make sure /etc/securetty has xvc0 and hvc0 |
| | 12 | {{{ |
| | 13 | egrep "xvc0|hvc0" /etc/securetty |
| | 14 | }}} |
| | 15 | * change tty1 to hvc0 in /etc/inittab |
| | 16 | {{{ |
| | 17 | sed -i 's#1:2345:respawn:/sbin/getty 38400 tty1#1:2345:respawn:/sbin/getty 38400 hvc0#' /etc/inittab |
| | 18 | }}} |
| | 19 | |
| | 20 | On the dom0: |
| | 21 | |
| | 22 | * For each domU config file in /etc/xen/ update kernel and ramdisk lines and add extra line: |
| | 23 | {{{ |
| | 24 | kernel = '/boot/vmlinuz-2.6.26-2-xen-686' |
| | 25 | initrd = '/boot/initrd.img-2.6.26-2-xen-686' |
| | 26 | ramdisk = '/boot/initrd.img-2.6.26-2-xen-686' |
| | 27 | extra = 'console=hvc0' |
| | 28 | }}} |
| | 29 | * edit /boot/grub/menu.lst |
| | 30 | {{{ |
| | 31 | # xenhopt=dom0_mem=268440 com1=115200,8n1 console=com1 |
| | 32 | # xenkopt=console=hvc0 |
| | 33 | # kopt=root=/dev/mapper/vg_XXXXXX0-dom0 ro console=ttyS0,115200n8 |
| | 34 | }}} |
| | 35 | * edit /etc/inittab |
| | 36 | {{{ |
| | 37 | sed -i "s#T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100#T0:23:respawn:/sbin/getty -L hvc0 115200 vt100#" |
| | 38 | }}} |
| | 39 | * perform etch -> lenny upgrade on dom0 - allow debconf to install new versions of /etc/xen-tools/xen-tools.conf and /etc/xen/xend-config.sxp. |
| | 40 | * update two xen files with needed customizations: |
| | 41 | * /etc/xen-tools/xen-tools.conf |
| | 42 | {{{ |
| | 43 | lvm = vg_gramsci0 |
| | 44 | dist = lenny |
| | 45 | }}} |
| | 46 | * /etc/xen/xend-config.sxp |
| | 47 | {{{ |
| | 48 | # (network-script network-dummy) |
| | 49 | (network-script network-bridge) |
| | 50 | }}} |
| | 51 | * ensure recent plain kernel is installed: |
| | 52 | {{{ |
| | 53 | aptitude install linux-image-686 |
| | 54 | }}} |
| | 55 | * ensure xen tools are properly upgraded: |
| | 56 | {{{ |
| | 57 | aptitude install aptitude install xen-utils-3.2-1 aptitude install xen-linux-system-2.6.26-2-xen-686 |
| | 58 | }}} |
| | 59 | * reboot |
| | 60 | * if all goes smoothly, purge all old linux/xen packages |
