RE: [Xen-users] Fwd: WinXP HVM access to CDROM ? 
| | 
Hi.   I’ve noticed that WinXP within Xen HVM can be booted only when cdrom
is hdc drive. Try it:   'phy:/dev/scd0,hdc:cdrom,r'   That works for me.

 Subject: [Xen-users] Fwd: WinXP HVM access to CDROM ?
     
Hello,
 I'm running Xen 3.2.1-rc1   - the version of Xen which comes with
Ubuntu 8.04
 I have a WindowsXP domU running fine using HVM (config below).
 However I cannot seem to get to to access the CD/DVD drive.
 
 My CD/DVD drive is /dev/scd0
 My domU config line is:
 
 disk    = [ 'phy:/dev/loop17,ioemu:hda,w', 'phy:/dev/scd0,xvdc:cdrom,r'
,]
 
 But windows does not detect the CDROM.
 I've tried xm block-attach ing this device but no difference.
 
 xm block-attach 3 phy:/dev/scd0 /dev/xvda2 r
 
 Can anyone tell me what the correct device naming should be for a HVM windows
 install running under Xen 3.2.1 ?
 
 I do not care for the CD/DVD in Ubuntu - I just want to dedicate it to the
Windows VM,
 
 Cheers,
 Paul
