{Xen-API] XCP/Ubuntu 12.04 - no cdrom in guests

Hello!

I'm trying to evaluate XCP on Ubuntu 12.04 in our lab.
I've used packages from default system repositories (xcp-xapi 1.3.2-5).
I've successfully connected to it using XenCenter, attached NFS ISO and
VHD storages and was able to import VMs created on neighbour XCP 1.5
Beta server.

But I have trouble installing new VMs using ISO images on ISO SR. My
guests simply "do not see" attached images.
Here is how it looks:

root [at] xcp0:/usr/lib/xcp/lib# xe vm-cd-list uuid=2c91cfd0-c892-598b-2ef5-557dda4ef9e3

CD 0 VBD:

uuid ( RO) : 4eaefa4c-41ad-3e85-df47-512b85ce0fd2

vm-name-label ( RO): Precise (1)

empty ( RO): false

userdevice ( RW): 3

CD 0 VDI:

uuid ( RO) : 1c961978-6435-408f-b558-b8f4f6220033

name-label ( RW): Bootable_UCSInstall_UCOS_UNRST_8.6.2.10000-14.sgn.iso

sr-name-label ( RO): ISOLIB

virtual-size ( RO): 4521836544

Looking at dmesg in guest i see following:

[ 94.211753] blkfront device/vbd/51760 num-ring-pages 1 nr_ents 32.

But can't find corresponding block device in /dev

What can be done to fix it?

Do 'xe sr-scan' or 'xe sr-update' with uuid of ISO sr. Note: you need to
do this on the pool master and do have same images on every host in the
pool.

Its a single-host install. And in dom0 I see correctly configured CD
VBD/VDI for VM and ISO-image. And even more - I see messages from
blkfront inside the guest VM, but no /dev/xvdd appears.

Anyway, I did sr-scan/sr-update - nothing happened.

I'm not sure yet. I've noticed this myself on XCP Ubuntu Precise. I will
hopefully get a chance to look into it in the next week or so.
