2. Start iscsid
$ iscsid
3. Discover and login to target:
$ iscsiadm --m discovery --t st --p $TARGET_IP
$ iscsiadm --m node --T $TARGET_IQN --p $TARGET_IP ---login
4. If the iSCSI LUN is part of a LVM Logical volume group
$ lvm vgscan
$ lvm vgchange --ay
5. Now mount your '/' partition
$ mount -/dev/path/to/root -/mnt/sysimage
$ mount --t bind -/dev -/mnt/sysimage/dev
$ mount --t proc proc -/mnt/sysimage/proc
$ mount --t sysfs sysfs -/mnt/sysimage/sys
6. Now you can chroot to the root fs of your installation if wanted

• When installing KVM or Xen guests, always create a partition for the guest disk, or create an LVM
volume. Guests should not be installed to block devices or raw disk devices. Anaconda includes
disk label duplication avoidance code, but when installing within a VM, it has no visibility to the disk
labels elsewhere on the host and cannot detect duplicates.
If guest filesystems, especially the root filesystem, are directly visible to the host, a host OS reboot
may inadvertantly parse the partition table and mount the guest filesystems. This can lead to highly
undesirable outcomes.
• The minimum memory requirement when installing all Red Hat Enterprise Linux packages (i.e. '*'
or '@everything' is listed in the %packages section of the kickstart file) on a fully virtualized Itanium
guest is 768MB. After installation, the memory allocated to the guest can be lowered to the desired
(BZ#507891)
amount.
• Upgrading a system using Anaconda is not possible if the system is installed on disks attached
using zFCP or iSCSI (unless booted from the disk using a network adaptor with iBFT). Such disks
are activated after Anaconda scans for upgradable installations and are not found. To update please
