[Fedora-xen] Can you attach CDs/DVDs/HDs to an XP Guest?

[David Levinger]

Thanks Dustin,

 

Your response gave me hope and I kept poking around and found the
following two previous email threads:

 

http://xen.markmail.org/message/55544ap2h34mzi3n?q=block-attach+hvm
<http://xen.markmail.org/message/55544ap2h34mzi3n?q=block-attach+hvm&page=

and 

http://xen.markmail.org/message/xxnkqhjgsqrtvukn?q=block-attach+hvm
<http://xen.markmail.org/message/xxnkqhjgsqrtvukn?q=block-attach+hvm&page=
2#query:block-attach%20hvm+page:2+mid:6eyxxqeg3vrrobe6+state:results>
&page=2#query:block-attach%20hvm+page:2+mid:6eyxxqeg3vrrobe6+state:results

And it looks like xm block-configure was the ticket! It hasn't worked for
me 100% but by setting the devices to "null" it works pretty darn good :-)

 

Thanks again,

 

David

David,

                I don't know how much this will help you, as I don't know
much about your setup.  I am running XP HVM guests on F7 (Moonshine) using
the old fashioned text xen method (/etc/xen/auto/guest.hvm, xm create, xm
destroy, etc), and I can't change actual CDs or DVDs in my XP guests.
That is to say, I think if a CD/DVD is in the drive when I start the guest
and hdc:cdrom is connected to /dev/cdrom in the hvm file, the CD/DVD in
the drive works, however, changing it out does not.  However, if hdc:cdrom
is connected to /dev/cdrom and there is no disc in the drive (or perhaps
even if there is), I can ues the xm block-attach and xm block-detach, for
instance:

xm block-list 2

xm block-detach 2 5632 -f

xm block-attach 2 file:///iso/lm70200.iso hdc:cdrom r

xm block-detach 2 5632 -f

xm block-attach 2 phy:/dev/cdrom hdc:cdrom r

In the above commands, I listed the block devices, determined which was
the cdrom, detached it, attached an iso, used it as needed in the guest,
detached the iso, and reattached the physical drive (even though it
doesn't work).  I can do this over and over again.  Going back to the
physical device probably isn't necessary, but I do it so I am always
starting from the same point.  The reason I doubt it matters is that once
XP is booted, it always shows that drive, detaching it doesn't make it
disappear, and reattaching it doesn't give it a new ID (even if scanning
for hardware changes between steps).  I am also fairly certain that trying
to attach one iso over another isn't sufficient.  If you eject the tray on
the cdrom drive from within xp, you're done until you reboot as far as I
can tell, but with the above steps, if you don't do that, it seems to work
alright.  I don't know if this will help you at all, seeing a how you more
than likely use virt-install, virt-manager, etc, but I figure it can't
hurt if there is a similar process for that system.  Good luck,

                Dustin

Hey guys and gals,

 

As the subject suggests, is it possible to block-attach a newly placed
CD/DVD/HD/Img file to an XP guest? I've done the "normal" block-attach
command and it says it has "attached" but nothing shows in the XP guest.
