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

["Tait Clarridge" <Tait.Clarridge@xxxxxxxxxxxx>]

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. :)

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
xen-3.0.3-41.el5
kernel-xen-devel-2.6.18-53.1.14.el5
xen-libs-3.0.3-41.el5
kernel-xen-2.6.18-53.1.13.el5
