[Xen-users] pygrub is failing to boot centos domu on Debian lenny dom0
I am trying to run a CentOS DomU on Debian Dom0 . I created a VM using QEMU and it boots fine.(Except network connectivity) Now for Debian Dom0 I created the new_centOS.cfg added following bootloader = "/usr/lib/xen-3.2-1/bin/pygryb" (there was no softlink from /usr/lib/xen-3.2-1/bin/pygryb to /usr/bin) boot = "c" full file uploaded here http://pastebin.com/daeGSSpS and then tried to boot got an error openworld:/etc/xen# xm create new_centOS.cfg Using config file "./new_centOS.cfg". Error: Bootloader isn''t executable about the above error on this link http://wiki.debian.org/Xen#A.22Error.3ABootloaderisn.27texecutable.22 some information was but it did not helped.As what they were saying I had already done. Then checked this link http://strugglers.net/~andy/blog/2008/01/20/red-hat-based-linux-under-xen-from-debian-etch/ I did usr/lib/xen-3.0.3-1/bin/pygrub /dev/virtualization/centos5-disk xvda I get a brub screen . A snapshot for the pygrub booting can be seen here http://farm5.static.flickr.com/4006/4626021351_d1a6f9c014_b.jpg But it fails to boot. Giving following message.
