 Hi Stephen,
 
 This is the same issue as kern/45671.  The fact that you don't get the
 CD-ROM device is actually the least of your trouble :-)  I don't know
 why (or if) an atapi device can attach to wdc@isa, but in any case the
 real issue is that you get wdc@isa, and that's because you don't get
 anything on the PCI bus (see kern/45671).
 
 The workaround for 45671 doesn't apply to a Xen HVM (because the actual
 CPU is seen).  I think it'd be better to use pmf_get_platform to check
 if "system-vendor" is "Xen" and "system-product" is "HVM domU" because
 that's what you get on XenServer 6.2 according to my dmesg(8) output.
 
 As a workaround, you can boot the install media with:
 
 boot netbsd -d
 
 And then at the ddb prompt, do:
 
 write pci_mode 1
 
 And then build a custom kernel with:
 
 options PCI_CONF_MODE=1
