- Since we'll be running VMs, the choice will be the server image, then press F4 to select the minimal virtual machine. This will install a slim kernel.Paravirtualisation should be used on all new VMs. Unfortunately this does not work with 64 bit guest. This is not a real problem, because 64 bit guest only are useful when more than 4 GB RAM is used, and currently 1 GB is the highest
- amount of RAM a VM is configured withWe will be running 64 bit VMs only - because they will be running for the next 2-3 years, we will be prepared for any machines that require alot of RAM (the Wowza VM already seems to need more than 3 GB now). There are no show stopper issues any more with 64 bit guests, and we'll be forward compatible.
- On all hosts that use LDAP authentication nscd will have to be installed (see bug #423252). This might actually be a good idea any way, especially for hosts that need to query LDAP a lot (such as the mailer Erasmus).
- Open-vm-tools are now 100% usuableusable, no custom kernel modules are needed. Because the tools make use of the DKMS system, kernel upgrades trigger recompilation of the affected kernel modules, making it it very convenient:
Code Block apt-get install --no-install-recommends linux-headers-`uname -r` open-vm-dkms open-vm-tools
- Syslog is replaced with rsyslog. This new logging daemon can also log to MySQL. This needs to be configured.
- The
sun-java6-jrepackage that used to reside in Hardy's multiverse repository, has been moved to the 'partner' repository (see/etc/apt/sources.list). - The hostname that is used during installation will be used to give Logical Volumes names in LVM. Choose a small generic name, so that subsequent clones will not have confusing LVM names.
