| 1. The buildsystemvm.sh script builds a 32-bit system vm disk based on the Debian Squeeze distro. This system vm can boot on any hypervisor thanks to the pvops support in the kernel. It is fully automated |
| 2. The files under config/ are the specific tweaks to the default Debian configuration that are required for CloudStack operation. |
| 3. The variables at the top of the buildsystemvm.sh script can be customized: |
| IMAGENAME=systemvm # dont touch this |
| LOCATION=/var/lib/images/systemvm # |
| MOUNTPOINT=/mnt/$IMAGENAME/ # this is where the image is mounted on your host while the vm image is built |
| IMAGELOC=$LOCATION/$IMAGENAME.img |
| PASSWORD=password # password for the vm |
| APT_PROXY= #you can put in an APT cacher such as apt-cacher-ng |
| HOSTNAME=systemvm # dont touch this |
| SIZE=2000 # dont touch this for now |
| DEBIAN_MIRROR=ftp.us.debian.org/debian |
| MINIMIZE=true # if this is true, a lot of docs, fonts, locales and apt cache is wiped out |
| |
| 4. The systemvm includes the (non-free) Sun JRE. You can put in the standard debian jre-headless package instead but it pulls in X and bloats the image. |
| 5. You need to be 'root' to run the buildsystemvm.sh script |
| 6. The image is a raw image. You can run the convert.sh tool to produce images suitable for Citrix Xenserver, VMWare and KVM. |
| * Conversion to Citrix Xenserver VHD format requires the vhd-util tool. You can use the |
| -- checked in config/bin/vhd-util) OR |
| -- build the vhd-util tool yourself as follows: |
| a. The xen repository has a tool called vhd-util that compiles and runs on any linux system (http://xenbits.xensource.com/xen-4.0-testing.hg?file/8e8dd38374e9/tools/blktap2/vhd/ or full Xen source at http://www.xen.org/products/xen_source.html). |
| b. Apply this patch: http://lists.xensource.com/archives/cgi-bin/mesg.cgi?a=xen-devel&i=006101cb22f6%242004dd40%24600e97c0%24%40zhuo%40cloudex.cn. |
| c. Build the vhd-util tool |
| cd tools/blktap2 |
| make |
| sudo make install |
| * Conversion to ova (VMWare) requires the ovf tool, available from |
| http://communities.vmware.com/community/vmtn/server/vsphere/automationtools/ovf |
| * Conversion to QCOW2 requires qemu-img |
