12277 UNIX/Linux Shell Scripting 14 hours This 2 day course gives an introduction to the writing of UNIX Shell scripts using the Korn and Bash shells and to the more advanced features of UNIX including the batch editor sed and the text file processing language awk. Although based on the Solaris version of UNIX running on a desktop PC, the principles learnt may be applied to all other versions of UNIX including Linux, AIX, HP-UX and SCO. The course takes the format of a workshop, with a mix of lecture, working examples and practical exercises. Although the content may be customised, at least 1 day is normally needed to cover the core elements. Full course notes are provided along with sample script files and free software tools for use in accessing a UNIX server.

359481 Virtualization with QEMU, KVM and Libvirt 14 hours This practical course contains topics addressed to system administrators, developers, embedded developers and ordinary desktop users (including managers) who would like to have an introduction to virtualization in general. After this course, administrators will be able to create private clouds for use in production, and developers will be able to test their code on multiple operating systems without needing a second PC or a non-x86 board. We understand that the set of topics presented in this course covered a wide range of subjects that might not be applicable for all customers. When booking this course, please specify what you wish to achieve using QEMU or KVM, and we will customize it by reallocating time from less relevant topics to the ones that would be important for you. Day 1 "Big picture" of the virtualization ecosystem History of QEMU development CPU features related to virtualization Installing QEMU from packages Installing QEMU from source Full-system emulators Using the QEMU console Available machine types and peripheral devices VirtIO Guest drivers Disk image formats Managing virtual machine snapshots Networking in virtual machines Graphics adapters Audio devices Nested virtualization Day 2 User-level emulators Registration of foreign binaries through binfmt-misc Cross-architecture chroots and containers The role of Libvirt in the virtualization ecosystem Supported hypervisors and container technologies QEMU Machine protocol (QMP) Running QEMU headless QXL video card and SPICE display Available SPICE viewers Creating virtual machines with "virt-install" and "virt-clone" command-line tools Using "virt-manager" graphical application to create and run virtual machines Editing virtual machine configuration and libvirt settings with "virsh" low-level tool Using libguestfs tools (guestfish, virt-sysprep) to manipulate disk image contents Networking and firewall in libvirt Accessing libvirt remotely Overview of web-based frontends for libvirt Bonus topics available in classroom only (i.e. only short descriptions, not demonstrations, are available in remote courses): Running Mac OS X in KVM (if at least one participant has a Mac with Linux installed) 3D graphics with VirGL 3D graphics with Intel Broadwell or Skylake GPU and igvtg (very experimental, requires custom kernel, may or may not work) Video card passthrough (if there is a desktop available with two video cards) USB device pass-through
