RE: [Xen-users] Add more disk

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

        If you want to try the method suggested by Andy Burns and you are
not using GPLPV drivers, I believe you would have to modify it as follows:
xm block-attach domu-name phy:/dev/vg-name/lv-name hdb w
        This may depend on your distribution, or I could even be wrong, but
I think xvdb is a PV device that Windows won't know what to do with where
hdb is a qemu device Windows will have a default driver for.  Also, if it
doesn't just show up and rescanning controllers in disk management doesn't
work you might have to scan for hardware changes in Windows.  All of that
being said, if you want to do it on the fly, we need to know how it didn't
work (error on the CLI, Windows didn't detect the device, Windows didn't
recognize the device, etc).  Also, regardless of whether you want to do it
on the fly, if you want it to be permanent, it does need added to your
config file (the same way as it was added on the fly if it was).

Quite simple, use a new file or LVM partition (probably the same
choice you use for the C: disk is good) on the domU and add it
dynamically with e.g.

xm block-attach domu-name phy:/dev/vg-name/lv-name xvdb w

It should then be visible inside windows (You might need to rescan
controllers in Disk management) and can be formatted. I'm using the
GPLPV drivers and can't remember if the disk dynamically shows up when
using tehe QEMU drivers.
