[Xen-users] No installation media (DVD-ROM) present in virtual machine during initial install

[urcabraz <urcabraz@xxxxxxxxx>]

I appreciate your help. I installed Fedora 7 on a quad core Intel CPU with Intel VT (hardware virtualization). I'm trying to get my first virtual machine installed, and the virtual machine starts up, but is presented on "first boot" only with the hard drive partition (/dev/hda == ata0-master (?)) but not with DVD-ROM ISO image (/dev/hdc == ata1-master (?)). This doesn't work, of course, because the OS hasn't yet been installed to /dev/hda.

Some preliminaries:

• using Fedora 7/Xen for hypervisor
• copied Fedora 7 x86_64 DVD to a *.iso on the local file system, and made sure its sha1sum matched official value
• I'm using the "Virtual Machine Manager" tool to set up the virtual machine
• I'm setting up a Fedora 7 x86_64 virtual machine supposedly to be installed from a virtual CD-ROM on the virtual machine, mapped from the *.iso file

Just before I launch the virtual machine for the very first time, I see this screen, and assume all is ready to go:

I then click the "Finish" button, the "system1 Virtual Machine Console" starts up, and I just see a BLACK screen, like this (and the BLACK screen looks like it wants to be there forever, 5+ minutes at least):

If I press the "Shutdown" button and then the "Run" button again, I get something like this:

I'm assuming the second run is configured identically to the first, especially since it appears the 'domain' configuration at /var/lib/xend/domains/...UUID.../config.sxp is the same in both cases (I'm supposing this file defines the essentials of the virtual machine, I had to hunt around for it for a while -- with some Google help too).

That config.xsp file contains this excerpt, which implies the *.iso file is not present in the instance at all as a virtual DVD-ROM drive: ... but wait a second, the second run is different from the first, I'll post excerpts of both versions!:

first run:

(image (hvm (kernel /usr/lib/xen/boot/hvmloader) (acpi 1) (apic 1) (boot c) (device_model /usr/lib64/xen/bin/qemu-dm) (pae 1) (serial pty) ) ) (status 0) (device (vif (bridge virbr0) (mac 00:16:3e:54:65:85) (uuid 4a405b94-393b-c815-6979-56f72895afe4) ) ) (device (vbd (uuid a34edc8c-7b05-b957-5a5e-853c784514f0) (bootable 1) (driver paravirtualised) (dev hda:disk) (uname phy:/dev/NoRaidVolGroupB/BogatzaServer1_RootFs) (mode w) ) ) (device (vkbd (uuid 035a6e0e-df78-4079-92f0-a9e65dd77245))) (device (vfb (vncunused 1) (keymap en-us) (type vnc) (uuid 217d3850-b8a9-7346-f0fe-ceee66015c3a) ) )

second version:

(image (hvm (kernel /usr/lib/xen/boot/hvmloader) (acpi 1) (apic 1) (boot c) (device_model /usr/lib64/xen/bin/qemu-dm) (pae 1) (serial pty) (notes (SUSPEND_CANCEL 1)) ) ) (status 1) (state ------) (store_mfn 127998) (device (vif (bridge virbr0) (uuid 4a405b94-393b-c815-6979-56f72895afe4) (script vif-bridge) (mac 00:16:3e:54:65:85) (type netfront) (backend 0) ) ) (device (vbd (uname phy:/dev/NoRaidVolGroupB/BogatzaServer1_RootFs) (uuid a34edc8c-7b05-b957-5a5e-853c784514f0) (mode w) (dev hda:disk) (backend 0) (bootable 1) ) ) (device (vkbd (backend 0))) (device (vfb (vncunused 1) (keymap en-us) (type vnc) (uuid 217d3850-b8a9-7346-f0fe-ceee66015c3a) ) )

In any case, I'm new to this and don't understand much of what's going on, but I expected to see something more like this, from someone else's virtual machine install experience:

• (XEN) (GUEST: 2) ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (6896 MBytes)
• (XEN) (GUEST: 2) ata0 slave: Unknown device
• (XEN) (GUEST: 2) ata1 master: QEMU CD-ROM ATAPI-4 CD-Rom/DVD-Rom
• (XEN) (GUEST: 2) ata1 slave: Unknown device

I only ever saw the QEMU HARDDISK ATA-u. Where is my DVD-ROM with the Fedora 7 files for the virtual machine install?!!?? Thank you for reading this far.
