[Spacewalk-list] Re-provision guest systems

[Jonathan DeHaan]

My virtualization is provided by Citrix Xen 5.6, I'm running Fedora 15 
guests with default kernels. SW is 1.4 with Oracle XE.

Koan downloads the kernel and initrd, and says to reboot. I issue 
'shutdown -r now', and on reboot, anaconda runs and follows the 
kickstart, properly registering itself with Spacewalk and reconnecting 
back to it's original systemid.

File preservation does not work, and there is no cobbler system record 
created. I tried manually copying a system record and editing it, but I 
may not have gotten all the right values in for ksmeta and 
redhat-management-key. With a system record, I can drop the --profile 
part from the koan command, and it works just as well, but file 
preservation still does not work.

The only case I can imagine that Xen paravirt would fail is if the 
kernel and booting configuration are not accessible to the guest. As 
Citrix Xen demonstrates, however, this is not the only way to set up Xen.

Fedora 11 guests on the same Citrix Xen cluster show up as non-virtual 
(I presume because of limited pvopts support in old kernels) and have no 
difficulty reprovisioning with file preservation working correctly.
