So, we read elsewhere to take the scsi part out. This givesNo better. Sigh. So, fire up virt-manager and do the install, making sure not to use LVM. For Eucalyptus, the first partition is the root, the second the rest of the disk space, and the third swap -- so install everything in the first partition. You can do the install without creating a swap partition or make it the second partition and go back and patch up /etc/fstab after booting within Eucalyptus.
You have to create the disk layout yourself, so that it's not LVM and there's no swap.
Then create a standard partition.
Make it mount on /, be EXT4, and take all the available space.
You'll be warned that there's no swap partition, but that's as planned.
That should do it for the disk setup.
Find out where the partition starts and ends:
$ parted /var/lib/libvirt/images/CentOS-6.4.img

We don't want to use a block size of 1 byte on CentOS, so we do a little calculation for the size: 8589934592/65536 = 131072 and the start: 1048576/65536 = 16. We can now grab the root filesystem:
$ dd if=/var/lib/libvirt/images/CentOS-6.4.img of=~beaty/CentOS-6.4.emi bs=65536 skip=16 count=131072
$ file ~beaty/CentOS-6.4.emi
/home/beaty/CentOS-6.4.emi: Linux rev 1.0 ext4 filesystem data (extents) (large files) (huge files)
To get the kernel and ramdisk:
$ mount -r -t ext4 -o loop,offset=1048576 /var/lib/libvirt/images/CentOS-6.4.img /tmp/centos
$ cp /tmp/centos/boot/vmlinuz-2.6.32-358.el6.x86_64 ~beaty
$ cp /tmp/centos/boot/initramfs-2.6.32-358.el6.x86_64.img ~beaty
I use the following script to bundle and upload; you'll have to change the file names and buckets to yours of course.
#! /bin/bash
KERNEL=vmlinuz-2.6.32-358.el6.x86_64
KERNELBUCKET=centos6
RAMDISK=initramfs-2.6.32-358.el6.x86_64.img
RAMDISKBUCKET=centos6
IMAGE=CentOS-6.4.emi
IMAGEBUCKET=centos6
# ---------------------------------------------
euca-bundle-image -i $KERNEL --kernel true
euca-upload-bundle -b $KERNELBUCKET -m /tmp/$KERNEL.manifest.xml
EKI=`euca-register $KERNELBUCKET/$KERNEL.manifest.xml | cut -f 2`
echo "EKI = $EKI"
euca-bundle-image -i $RAMDISK --ramdisk true
euca-upload-bundle -b $RAMDISKBUCKET -m /tmp/$RAMDISK.manifest.xml
ERI=`euca-register $RAMDISKBUCKET/$RAMDISK.manifest.xml | cut -f 2`
echo "ERI = $ERI"
euca-bundle-image -i $IMAGE --ramdisk $ERI --kernel $EKI
euca-upload-bundle -b $IMAGEBUCKET -m /tmp/$IMAGE.manifest.xml
euca-register $IMAGEBUCKET/$IMAGE.manifest.xml
Now, you can find the associated new filesystem and swap partition, and hook those up in /etc/fstab:# blkid
/dev/vda1: UUID="755338e8-3b28-4f74-afde-6efe8319e4de" TYPE="ext4"
/dev/vda2: UUID="9cd82546-4c6c-4ca6-9b97-ccd96a6a82cc" SEC_TYPE="ext2" TYPE="ext3"
/dev/vda3: UUID="52a0a91a-c910-4c08-9d73-6223cfaba293" TYPE="swap
Here's a diff of /etc/fstab
You might also have to change the network configuration so that the NIC provided by Eucalyptus is used as eth0 (or you can just remove the file and have the OS regenerate it):
# diff /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.orig
