Debian Squeeze

Still testing at time of writing but frozen so almost stable ;-)

• Installing squeeze from daily image (17/08/2010)
  • Complains about missing bnx2/bnx2-mips-09-5.0.0.j3.fw & bnx2/bnx2-rv2p-09-5.0.0.j3.fw
    • Get it on another machine and put it on USB stick: aptitude install firmware-bnx2 ; cp /lib/firmware/bnx2/bnx2-*-09-5.0.0.j3.fw /media/XXXX
    • Actually I had also an additional Intel network card so I could have skipped this step...
  • Partitionning:
    there is a first primary partition for Dell Utilities (FAT16), I left it just in case...;
    there is also a second primary partition: 2Gb of FAT32, empty, so I deleted it.
    partition #2: primary 10Gb ext3 / label=ROOT
    partition #3: primary 16Gb swap
    partition #5: logical 2Tb physical volume for LVM
    Configure LVM / ok to write table / Create VG with sda5, called vg0 (will be used by XEN)
  • Tasksel: SSH & standard utilities
  • Reboot
• SSH: PermitRootLogin no / ssh-copy-id ...
• Install mc, sudo (adduser xxx sudo)
• Renaming interfaces (always easier to remember what's plugged where...)
  • à la ifrename
    • aptitude install ifrename
    • Create /etc/iftab then reboot

intelD mac 00:1b:21:xx:xx:xx
bcm1   mac 84:2b:2b:xx:xx:xx
bcm2   mac 84:2b:2b:xx:xx:xx

• • à la udev
    • actually we don't need ifrename because udev is now doing the same, see /etc/udev/rules.d/70-persistent-net.rules, you can simply change the NAME key
  • Be sure the old name is not used anywhere else in your config, typically in /etc/network/interfaces

XEN: installation

• see notes on Debian wiki
• aptitude install linux-image-2.6.32-5-xen-amd64 xen-tools xen-utils
• backup /etc/xen/xend-config.sxp
• edit /etc/xen/xend-config.sxp, and uncomment line "(network-script network-bridge)" or for a non-default interface ethX: "(network-script 'network-bridge netdev=ethX')"
• reboot
• aptitude remove --purge linux-image-2.6.32-5-amd64 linux-image-2.6-amd64
• /etc/default/grub => GRUB_DEFAULT=2
• update-grub
• reboot
• cat /proc/xen/capabilities #(to check xend is running)

XEN: guest creation

• If you've a proxy it's much easier to have it defined in the environment variables:
  • Edit /etc/environment

http_proxy=http://myproxy:port

• • Logout/login
• Edit the config file for creating images (/etc/xen-tools/xen-tools.conf) to your needs:
