- Installation, see Booting over the network. Customized package selection, everything deselected except base utilities.
- Log in for the first time
- Create swap file:
# dd if=/dev/zero of=/swapfile1 bs=1024 count=262144
# mkswap /swapfile1
# swapon /swapfile1
# chmod 640 /swapfile
- Add following line to /etc/fstab:
/swapfile1 swap swap defaults 0 0
- Install kernel-xen, install group Virtualization.
- Install sudo, xauth.
- Turn off selinux in /etc/selinux/config
- Set a static IP dom dom0, since the xen kernel doesn't like to bring up eth0 through dhcp
- Create image for domU's through virt-manager; this hangs after answering two questions; copied tree locally and set up local httpd. Doesn't work and neither does ftp work. New approach is kickstart:
system-config-kickstart noarch 2.6.19.1-1.el5 base 985 k
Installing for dependencies:
comps-extras noarch 11.1-1.1.el5.centos base 46 k
notify-python x86_64 0.1.0-3.fc6 base 13 k
pirut noarch 1.2.10-1.el5.centos.1 base 246 k
pykickstart noarch 0.43-1.el5 base 127 k
system-config-language noarch 1.1.18-1.el5 base 68 k
- Created minimal config, succeeded in creating image through ftp
- Run yum update, and add exclude=kernel* to /etc/yum.conf
- Check whether correct kernel is configured in /boot/grub/menu.lst, then reboot
- On domU www2, networking doesn't work. Form of interfaces on dom0: vif<domid>.<vifid> where the domid can be checked with xm list. Reconfigured network to static IP, restarted domU, works.
- Test booting with either disk decoupled. Works after installing GRUB on 2nd disk.
- Made /dev/md0 for /boot, /dev/md1 with 5G for the dom0, the rest of the disk /dev/md2 and LVM'ed.
- Straight copy of an LVM device to another works.
- After rebooting, RAID /dev/md2 gone. Had to assemble it:
# mdadm -A /dev/md2 /dev/sda3 /dev/sdb3
- Add extra configuration line to /etc/mdadm.conf, hoping that this helps.
Todo:
- Boot with laptop and serial cable
- Make SMART disk status readout for Zabbix
- Check out logwatch
- Set up tripwire
- How important is the UUID and the MAC address settings in Xen config files?
- Installing SVN on www1
- How does VNC function with the virt-manager utility?
- Lock down sshd
- Remove server keys from image, set IP address, change MAC address, shut down and remove superfluous services
- Set hostname and static IP on www2.
- Install s/w on www2.
- Lock down dom0
- Copy www2 to ns1.
