Set up F15 PV DomU at Xen 4.1 (kernel 3.0.0-5-generic) Dom0 on Ubuntu Oneiric

Following bellow is the first attempt to create PV domain at stock Xen 4.1 Dom0 on top Ubuntu Oneiric (alpha2 +) running kernel 3.0.0-5-generic. One bug in system configuration was fixed after initial install. I added to /etc/modules:


xen-gntdev
xen-blkback
xen-netback


Before you begin make sure

Then install keymaps on the box with stock Xen 4.1
in expected by xen location /usr/share/qemu/keymaps

root@boris-P5Q-E:/usr/share# mkdir qemu

*************************************************

Created installation profile


name="VF15"
memory=2048
disk = ['phy:/dev/sda8,xvda,w' ]
vif = [ 'bridge=br0' ]
vfb = [ 'vnc=1,vncunused=1']
kernel = "/root/vms/f15/vmlinuz"
ramdisk = "/root/vms/f15/initrd.img"
vcpus=2
on_reboot = 'restart'
on_crash = 'restart'


Vmlinuz , initrd.img downloaded from images/pxeboot folder local Apache Mirror.Started install . It requires "Tab" and good sense of wich button is current now.Mouse is a live, but actually useless. One more notice F15 (vs F14 ) goes directly to Fedora's Repos on Net. It requires 2-8 MBit/sec stable internet connection ( ADSL) install to be done in reasonable time frame.


# xm create f15.install
# vncviewer localhost:0

Created runtime profile :


name="VF15"
memory=2048
disk = ['phy:/dev/sda8,xvda,w' ]
vif = [ 'bridge=br0' ]
vfb = [ 'vnc=1,vncunused=1']
bootloader = "/usr/lib/xen-4.1/bin/pygrub"
on_reboot = 'restart'
on_crash = 'restart'


# xm create f15.pyrun
# vncviewer localhost:0

During runtime :-
# virsh dumpxml VF15 > VF15.xml
Then shutdown domain and removed uuid line from XML-profile
# virsh define VF15.xml
