[Xen-users] WinXP CD-ROM problems

I''m running Xen on RHEL5.

I''ve got two problems with CD-ROMs.

In my .hvm file, I''ve got the following line:

disk = [ ''phy:/dev/VG_Guests/WinXP-001,ioemu:hda,w'',
''file:/opt/xen_stuff/winxp.iso,hdc:cdrom,w'',
''phy:/dev/scd0,hdd:cdrom,r'' ]

The first CD-ROM,  (the one linking to the file winxp.iso), appears to
WinXP to be corrupted.  I''m able to mount that iso in the main OS so
I''m thinking this is just some weird Xen/WinXP problem.  I''m
not sure
when this started as it is the WinXP Install disk and I don''t normally
need it.  It worked originally when I set this up.

The next and more pressing problem is that when I pop a CD into the
CD-ROM drive, WinXP 99 times out of 100 doesn''t realize a new disk has
been inserted and doesn''t update the listing.  This has made
installing new software impossible.

Can someone please help?

Thanks in advance.

-J

RE: [Xen-users] WinXP CD-ROM problems

Hi Just,

You need to change the CDROM part of the disk = to look like

''file:/opt/xen_stuff/winxp.iso,ioemu:hdc:cdrom,r''

That should solve your problem, but make sure you remove the
''phy:/dev.....'' line as well as it will conflict.

Cheers,
Tait

This didn''t solve the problem with WinXP thinking the disk is
corrupted.

Also I want WinXP to be able to access both the iso and the real
physical CDROM on the box.  If I take out the 2nd CDROM (the one with
phy:/dev...) WinXP doesn''t seem to know anything about the physical
one.

What can I do?

Thanks.

RE: [Xen-users] WinXP CD-ROM problems

If the phy:\ is removed it won''t see it. That is a given, I
haven''t had
much luck with hooking xen to a physical cdrom device.

How did you copy the WinXP install disk? What messages are you getting,
is it from the Xen BIOS or something else...

I have had no issues installing Windows XP in Xen before... do you mind
posting your entire .hvm file and maybe the specs of your rig?

Thanks,
Tait

RE: [Xen-users] WinXP CD-ROM problems

Ok, Have you tried shutting down the VM completely (not just a reboot)
and bringing it back up again?
Have you upgraded any part of your host recently? Or of your Xen
installation?

Best,
Tait

Rebooting does cause WinXP to see the new disk in the drive.  However
that doesn''t really work since rebooting in the middle of the software
install means I have to start over with disk 1.

Updates are done whenever RH makes them available.

Currently installed packages are:
xen-devel-3.0.3-41.el5
kernel-xen-2.6.18-53.1.14.el5
kernel-xen-devel-2.6.18-53.1.13.el5

kernel-xen-devel-2.6.18-53.1.14.el5

Re: [Xen-users] WinXP CD-ROM problems

In order to change cd-roms, you need to detach/re-attach the device for
WinXP to re-read the drive.  However I''ve noticed (at least in xen 3.1)
that you have attach a "dummy" drive before re-attaching the real
drive.

Here''s what i use from dom0:
/usr/sbin/xm block-configure <domU> file:/xen/foo.iso hdc:cdrom r
/usr/sbin/xm block-configure <domU> phy:/dev/cdrom hdc:cdrom r

where hdc:cdrom is the drive in the hvm config.

Rebooting does cause WinXP to see the new disk in the drive.  However
that doesn''t really work since rebooting in the middle of the software
install means I have to start over with disk 1.

RE: [Xen-users] WinXP CD-ROM problems

Ok,

To switch the cds mid install type the following in the command line:


xm block-configure <domain> file:/path/to/2ndxpdisk.iso hdc:cdrom r


That should switch it out for you. :)
