Ok, solved this problem by reducing the memory in dom0 to 128 meg. xm mem-set 0 128 and using 256 meg in the guest. not a very graceful error but the blue install FC5 screen is up.

Xen is running. I am having problems with setting up a proper guest location for the install. I did a loop back mount of a DVD iso image for FC5, then shared it with NFS in theory I want to use this to load my guest in xen. mount -o loop -t iso9660 FC-5-i386-DVD.iso /mnt then share /mnt on nfs. xenguest-install.py What is the name of your virtual machine? guest1 How much RAM should be allocated (in megabytes)? 256 What would you like to use as the disk (path)? /home/myhome/guest1 What is the install location? nfs:192.168.1.100:/mnt is the path here correct or do I need a sub directory of the ISO image for location ? here is the debug: Starting install... libvir: Xen Daemon error : POST operation failed: No such domain guest1a Failed to get devices for domain guest1 Traceback (most recent call last): File "/usr/sbin/xenguest- install.py", line 460, in ? main() File "/usr/sbin/xenguest-install.py", line 451, in main start_paravirt_install(name, ram, disk, mac, uuid, src, options.extra) File "/usr/sbin/xenguest- install.py", line 331, in start_paravirt_install dom = conn.createLinux(cfgxml, 0) File "/usr/lib/python2.4/site-packages/libvirt.py", line 207, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed') libvirt.libvirtError: virDomainCreateLinux() failed Has anyone seen this problem and know how to work around it. thanks, </div><div>Ron Wahler <a href="http://www.positive-logic.net" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> http://www.positive-logic.net </a> </div></blockquote></div>
