Hi All,
Has anyone worked out a way of accessing
a CDROM from a Windows guest while using the GPLPV drivers?
I don't really mind whether access is
mapped to the physical device or an ISO image, as long as I can change
the media without having to reboot the domU.
My configuration:
dom0 = CentOS 5.3, Xen 3.3.1
domU = Windows Server 2008 64-bit, GPLPV
version 0.10.0.69
Tried the following disk specs in the
domU config - with the same result:
disk = [ 'phy:/dev/cciss/c0d0p3,xvda,w',
'phy:/dev/hda,hdc:cdrom,r' ]
disk = [ 'phy:/dev/cciss/c0d0p3,xvda,w',
'file:/iso/cdrom.iso,hdc:cdrom,r' ]
What I can see under Windows is
* a yellow exclamation mark in Device
Manager on device "Intel 82371SB PCI Bus Master IDE Controller"
* two devices "Xen Block Device
Driver" under Storage Controllers
* no sign of a CDROM drive in either
Explorer or Disk Management
# xenstore-ls /local/domain/19/device

How you managed to install GPLPV drivers on Windows 2008 64-bit?
I mean what method you used to overcome unsigned drivers issue?
