Re: [Xen-devel] Backport pygrub grub2 support to 3.4-testing

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

   Under Xen 4.0-rc4 (rc5) i can create  Ubuntu Karmic Server HVM DomU with image, say  on /dev/sdb5, and immediately load Karmic PV DomU via
/usr/local/bin/pygrub on /dev/sdb5 (/dev/xvda1 mounted on "/", /dev/xvda2 - swap).
  Fresh clone Xen 3.4.3 doesn't allow me to reproduce this procedure.
Bootloader returns no data, and i still have to copy kernel and ramdisk
to Dom0 add /etc/init/hvc0 at DomU (edited as usual)  and then load Karmic Server PV DomU via profile :-

name="KarmicPV"
memory=2048
kernel="./vmlinuz-2.6.31-14-server"
ramdisk="./initrd.img-2.6.31-14-server"
disk=['phy:/dev/sdb5,xvda,w']
extra="root=/dev/xvda1 ro console=hvc0"
vif= [ 'bridge=eth0']

Profile :

name="KarmicPV"
memory=2048
bootloader="/usr/local/bin/pygrub"
disk=['phy:/dev/sdb5,xvda,w']
vif= ['bridge=eth0']
vfb= ['vnc=1,vncunused=1']

doesn't work ( pygrub returns no data).

Xen has been built via directory :-

root@ServerKoala:/usr/src# cd xen-3.4-testing.hg
root@ServerKoala:/usr/src/xen-3.4-testing.hg# hg log |more

Smashing, cheers!
