Re: [Xen-users] Install from CD
qemu works well, as many of the partition types that Xen supports are also
supported by qemu. Of course, the CD is unlikely to contain a Xen kernel,
so after the install, you will need to install the modules and stuff.
here are some notes I made for a client that uses systemimager to manage
their boxes; With this they can install any of their existing
systemimager images to a VBD partition. (with an OVERRIDES folder that
adds the modules for the xen kernel and moves /lib/tls and stuff)
this way it each domU looks to have only one partition when viewed from
the dom0, but from within the domU it has all the partitions systemimager
made.
first, your install image must support one of the network adaptors
exported by qemu, like the NE2000 (or not use the network, that is fine
as well.)
in my client's system, they were booting off a floppy that ran the
systemimager stuff, so I use a floppy image, but QEMU has an option for
adding a virtual cdrom drive as well.
I made the floppy image with dd if=/dev/fd0 of=floppy.img
Mount -oloop floppy.img /mnt/floppy
Edit /mnt/floppy/local.cfg
copy in new kernel
Umount /mnt/floppy
Boot the floppy with the following command on dom0:
qemu -hda /dev/sda5 -no-kqemu -nographic -fda floppy.img -boot a
-net nic -net tap
where /dev/sda5 is the partition to install into (so in my disk section I
would use phy:/dev/sda5)
to make networking work with qemu, you want a /etc/qemu-ifup that looks
something like this
/sbin/modprobe tun
/sbin/ifconfig $1 promisc 0.0.0.0
/usr/sbin/brctl addif xenbr0 $1

Subject: [Xen-users] Install from CD
I have read some things that lead me to believe that I can do this. Do I need to
make an iso image of the cd then loopback mount it and make a config file that
points to the cdrom as the active partition? Is it even possible to do this and
if it is, will I need to patch the kernel or just move the
/lib/modules/2.<kernel> over to the new VM?
Thanks for any help,
Jon
