[Xen-users] Booting pv-ready distro installer.iso as Xen PV DomU drops to grub prompt?

[lyndat3@xxxxxxxxxxxxx]

Hi.

I have Xen 4.5 installed & booted on an opensuse UEFI machine.

My toolstack of choice is Xen's native/default 'xl'.

I'm trying to launch a supposedly pv-capable distro-installer .iso as a PV 
guest using the pvgrub2 bootloader.

The iso contains

        mount -o loop openSUSE-13.2-DVD-x86_64.iso /mnt/iso
        cd /mnt/iso
        find . | grep xen | egrep "/xen|/initrd|/vmlinuz|/grub|/kernel"
                ./boot/x86_64/initrd-xen
                ./boot/x86_64/vmlinuz-xen
                ./suse/x86_64/grub2-x86_64-xen-2.02~beta2-20.5.1.x86_64.rpm
                ./suse/x86_64/kernel-xen-3.16.6-2.1.x86_64.rpm
                ./suse/x86_64/kernel-xen-devel-3.16.6-2.1.x86_64.rpm
                ./suse/x86_64/xen-4.4.1_06-3.3.x86_64.rpm
                ./suse/x86_64/xen-doc-html-4.4.1_06-3.3.x86_64.rpm
                ./suse/x86_64/xen-kmp-default-4.4.1_06_k3.16.6_2-3.3.x86_64.rpm
                ./suse/x86_64/xen-kmp-desktop-4.4.1_06_k3.16.6_2-3.3.x86_64.rpm
                ./suse/x86_64/xen-libs-4.4.1_06-3.3.x86_64.rpm
                ./suse/x86_64/xen-tools-4.4.1_06-3.3.x86_64.rpm
                ./suse/x86_64/xen-tools-domU-4.4.1_06-3.3.x86_64.rpm

This is the DomU .cfg I'm using

        cat test.cfg
                boot = 'd'
                disk = 
['/home/lt/work/openSUSE-13.2-DVD-x86_64.iso,hdd:cdrom,r',]
                kernel = '/usr/lib/grub2/x86_64-xen/grub.xen'
                maxmem = 2048
                memory = 2048
                name = 'test'
                netif = 'yes'
                vif = [ 'mac=00:16:3E:01:01:01, bridge=br0, vifname=vifO',]
                vnc = 0
                sdl = 0
                stdvga = 1

When I exec 'xl create ...' at the Dom0, I just get dropped to a "grub" prompt.

Asking about it @ my disto ML, the suggestion so far is to add another tool 
into the mix, 'vm-install'.  That's causing MORE problems.

I'd really like to underestand & solve this with "just" Xen's native/default xl 
toolstack.

How do I get past the grub prompt to the usual installer opened in a VNC window?
