I have an Athlon64 system with FC4-x86_64 running. For several reasons I also would like to have a FC3_i386 system running at the same time. How can I do that?
I tried to use Xen (the 3.0-unstable-x86_64) but it did not work (could not find my root partition after the xen kernel was loaded, probably due to missing SATA support in the kernel). Neither could I compile Xen-2.7 myself (gcc4 complained about a struct with unkown length, gcc32 issued a warning which is treated as an error in by the xen Makefiles).
So I created an ext3 filesystem in an ordinary file and mounted it. Then I thought I could install FC3_i386 into that file so that I later can chroot into it. But since the installer (autorun) of FC3_i386 needs to be root I am afraid that it messes up my currently runnning system.
Do you have some links, help or additional information for me?
I hope the following may help you
On your running x86_64 linux take a backup of /etc/fstab. Edit your /etc/fstab and replace the label references to appropriate node references. (Use /etc/mtab to find the nodes) Example
The original file is ------------------------- LABEL=/ / ext3 defaults 1 1 LABEL=/usr /usr ext3 defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 LABEL=/opt /opt ext3 defaults 1 2 none /proc proc defaults 0 0 none /dev/shm tmpfs defaults 0 0 /dev/sda2 swap swap defaults 0 0 /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
Modified file will be --------------------------- /dev/hda1 / ext3 defaults 1 1 /dev/hda2 /usr ext3 defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 /dev/hda5 /opt ext3 defaults 1 2 none /proc proc defaults 0 0 none /dev/shm tmpfs defaults 0 0 /dev/sda2 swap swap defaults 0 0 /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
Reboot the machine and boot it with FC3_i386 CD
during installation create a new partitions for (/ and /usr)
(You can still use the same swap, home [if a seperate partition] and opt partitions if you don't have to use any binary from them)
select the partitions to be formatted using disk druid very carefully. Don't format what is not created newly.
Proceed with the installation.
To fix the boot (If you face some problem)!! Boot the machine with the last installed linux (FC3_i386) and edit the /boot/grub/grub.conf file appropriately.
Please be careful when making new partitions and naming them. There is a high risk of loosing data if something is done accidentally!!

OT question:
From where did you find Xen 3.0 x86-64 tools (and kernel) for FC4?
AFAIK Xen is only supported (both host and guest) under i386.

I created an LVM2 logical-volume per distro release, e.g., fc3-i386, and then used QEMU to install from the DVD images. I was surprised that it worked so well. After the installation, I manually fixed up the environment (/etc/modprobe.conf, etc.) to also run with User-Mode Linux. Xen will of course provide better performance.
