Updating or modifying a VNX root filesystem
In order to update or modify a VNX root filesystem (rootfs from now on), you have to:
- Using the vnx_modify_rootfs tool (recommended):
vnx_modify_rootfs <rootfs_name>
being <rootfs_name> the rootfs filename.
virsh create rootfs_XXX.xml
and manually opening the console using:
virt-viewer VMNAME
being VMNAME the name or number assigned by libvirt to the virtual machine (you can get it with "virsh list" command or just looking for the <name> tag in root_fs_XXX.xml file).
</ul>
Modify root filesystem scenarios (root_fs_XXX.xml)
To modify a root filesystem, for example, installing new software packages, just start the associated libvirt scenario with:
To easy the process, you can use the vnx_modify_rootfs simple script that starts the virtual machine and opens the console:
