First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a while I struggled with the "Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no shstrtab\n')" error but thanks to Nick Couchman from [1]http://lists.xensource.com/archives/html/xen-users/2008-03/msg00603.html, I've passed that. Now I'm stuck with a kernel panic situation. Unfortunately the kernel panic error doesn't appear using "xm console" and flashes so quickly through "virt-viewer" that I can't get any details.
Stop the guest and edit /etc/xen/<guest> cfgfile.
Remove (or comment out) the vfb line, and then restart the guest.
Now you get the full console output to "xm console".
