In order to speed up testing, it is often easy to build an individual component and repackage that into the install images.
The install.img contains the necessary file for the host installer to boot and install XenServer/XCP. This is a gzip compressed archive which can be unpacked and repacked as follows:
# Unpack mkdir dump sudo bash -c 'cd dump; zcat ../install.img | cpio -idu' # Repack sudo bach -c 'cd dump; find . | cpio -o -H newc | gzip -9c > ../install.img'
The main.iso/main-xcp.iso are the images used to install XenServer/XCP via the CD drive. This contains the install.img in addition to all the XenServer/XCP files. As this is an ISO file it can just be mounted to view the files. However, to make changes this must be copied to become read/write.
# Unpack mkdir mnt sudo mount -o loop main.iso mnt sudo cp -r mnt mnt-rw # Repack echo "/boot 1000" > main.list sudo bash -c 'cd mnt-rw; \ mkisofs -joliet -joliet-long -r \ -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat \ -no-emul-boot -boot-load-size 4 -boot-info-table \ -sort ../main.list \ -V "XenServer-6.0.50 Base Pack" \ -o ../main.iso .'
# Unpack mkdir dump sudo bash -c 'cd dump; tar xf ../dom0fs.tar.bz' # Repack sudo bash -c 'tar --directory dump -cjf dom0fs.tar.bz .'
