Downloading VNX root filesystems

You can download VNX preconfigured root filesystems from VNX repository at http://vnx.dit.upm.es/vnx/filesystems.

All root filesystems but Fedora and CentOS ones have a "root" and a "vnx" account with password "xxxx". Fedora and CentOS systems have password "xxxxxx".

Naming convention

Root filesystems names follow this format:

vnx_rootfs_<virtplatform>_<osname>-<osversion>-[gui-]<rootfsversion>.<ext>

being:

  • <virtplatform>: the virtualization platform the root filesystem was created for (kvm, uml, etc).
  • <osname>: the name of the operating system (or distribution in the case of Linux). Ej: ubuntu, freebsd, win7, etc.
  • <osversion>: the version of the OS.
  • gui: included if the root filesystem has a graphical user interface
  • <rootfsversion>: the version of the rootfs itself.
  • <ext>: the extension of the image. For example: qcow2.

Example:

  • vnx_rootfs_kvm-ubuntu-11.04-v022.qcow2 is a VNX root filesystem created with KVM, with an Ubuntu 11.04 without gui installed. The version of the rootfs is v022 and the format is qcow2.

Downloading instructions

Use the commands below to download and install root filesystems (the creation of the symbolic link at the end is optional; create it if you want a rootfs to be the default filesystem to be used by the example scenarios).

IMPORTANT: root filesystems are not updated any time VNX version changes. So, after download and install a rootfs, you have to update the VNXACE daemon following the procedure described here.

KVM root fylesystems

UML root filesystems

If you plan to use the old UML root filesystems created for VNUML, you have to download the rootfs itself:

# VNUML vnx_rootfs_kvm_tutorial and kernel
cd /usr/share/vnx/filesystems
wget -N http://vnx.dit.upm.es/download/vnx/filesystems/vnx_rootfs_uml-debian-6.0-v022.bz2
bunzip2 vnx_rootfs_uml-debian-6.0-v022.bz2
ln -s vnx_rootfs_uml-debian-6.0-v022 rootfs_tutorial
wget -N http://vnx.dit.upm.es/download/vnx/filesystems/vnx_rootfs_uml-n3vlr-0.11-v022.img.bz2
bunzip2 vnx_rootfs_uml-n3vlr-0.11-v022.img.bz2
ln -s vnx_rootfs_uml-n3vlr-0.11-v022.img rootfs_light

And the associated kernel:

cd /usr/share/vnx/kernels
wget -N http://jungla.dit.upm.es/~vnx/download/kernels/linux-2.6.18.1-bb2-xt-4m
chmod +x linux-2.6.18.1-bb2-xt-4m
ln -s linux-2.6.18.1-bb2-xt-4m linux
