| 1 | Installing a Scripts guest on a Xen host |
|---|
| 2 | ---------------------------------------- |
|---|
| 3 | |
|---|
| 4 | You need to create the volumes to use: |
|---|
| 5 | |
|---|
| 6 | lvcreate -n $MACHINE-root --size 50.00G $HOST |
|---|
| 7 | lvcreate -n $MACHINE-swap --size 10.00G $HOST |
|---|
| 8 | lvcreate -n $MACHINE-cache --size 11.00G $HOST |
|---|
| 9 | |
|---|
| 10 | /-------------------------------------------------------------------\ |
|---|
| 11 | Note: If you need to manually format the the swap and cache |
|---|
| 12 | partitions (for example, you are migrating a host from 'migrate'), |
|---|
| 13 | these commands should work. If in doubt, consult the kickstart. |
|---|
| 14 | |
|---|
| 15 | # Use fdisk to generate a DOS partition table, and a single |
|---|
| 16 | # partition extending the entire volume. |
|---|
| 17 | fdisk /dev/$HOST/$MACHINE-swap |
|---|
| 18 | fdisk /dev/$HOST/$MACHINE-cache |
|---|
| 19 | # Figure out what kpartx is going to make the devices as |
|---|
| 20 | # (e.g. $SWAP_DEV and $CACHE_DEV) |
|---|
| 21 | kpartx -l /dev/$HOST/$MACHINE-swap |
|---|
| 22 | kpartx -l /dev/$HOST/$MACHINE-cache |
|---|
| 23 | # Read out the partition tables |
|---|
| 24 | kpartx -a /dev/$HOST/$MACHINE-swap |
|---|
| 25 | kpartx -a /dev/$HOST/$MACHINE-cache |
|---|
| 26 | |
|---|
| 27 | # FORMAT! |
|---|
| 28 | mkswap $SWAP_DEV |
|---|
| 29 | mkfs.ext4 -O ^has_journal -m 0 -N 1000000 $CACHE_DEV |
|---|
| 30 | |
|---|
| 31 | # Remove the devices |
|---|
| 32 | kpartx -d /dev/$HOST/$MACHINE-swap |
|---|
| 33 | kpartx -d /dev/$HOST/$MACHINE-cache |
|---|
| 34 | \-------------------------------------------------------------------/ |
|---|
| 35 | |
|---|
| 36 | Make sure that the console has an entry for this host: |
|---|
| 37 | |
|---|
| 38 | vim /etc/conserver/conserver.cf |
|---|
| 39 | |
|---|
| 40 | If it doesn't, add: |
|---|
| 41 | |
|---|
| 42 | console $MACHINE { |
|---|
| 43 | master $HOST; |
|---|
| 44 | include xen; |
|---|
| 45 | } |
|---|
| 46 | |
|---|
| 47 | We use Kickstart to to initial Fedora configuration. Installing a new |
|---|
| 48 | vanilla machine is as easy as: |
|---|
| 49 | |
|---|
| 50 | xm create scripts-server machine_name=$MACHINE install=fXX && console $MACHINE |
|---|
| 51 | |
|---|
| 52 | The only prompt (near the beginning of the install process) should be |
|---|
| 53 | for the root password, and at the end, when it asks you to reboot. |
|---|
| 54 | Say yes, and the machine will power down, and then restart without |
|---|
| 55 | the install parameter: |
|---|
| 56 | |
|---|
| 57 | xm create scripts-server machine_name=$MACHINE && console $MACHINE |
|---|
