Hi,  I have OpenSuse 11.4 installation with 2.6.37.6-.0.5-xen kernel, where I tried to setup another instance of 11.4 on the same machine using paravirtualization. Both host and guest are 32 bit installations, further my processor supports vmx.    I proceeded with Guest OS installation and at the end of the installation it goes to reboot and never comes up. I checked the image disk which is also deleted by the time.     And when it tries to boot it gave following message "Bootloader didn't return any data! V, start failed ". After reading the bug https://bugzilla.novell.com/show_bug.cgi?id=685064 , I updated the kernel to be 2.6.37.6-44-xen . However I am still having the same issue. Please find following error log at xend.log. Highly appreciate your help on this.! Cheers!
