ok,
after has been resolved the problems with fedora core 6 in my laptop
(compaq r3000), running xen and SELinux disabled, i try to run the koan in
my laptop.
The scenario as follows:
my cobbler server is 136.145.116.114. I set up the next on it:
# cobbler distro add --name="test1" --kernel=/boot/vmlinuz-2.6.18...
--initrd=/boot/initrd-2.6.18...
# cobbler profile add --name="test1-profile" --distro="test1"
--kickstart=/root/anaconda-ks.cfg.virtual --virt-name="cobblertest"
--virt-file-size=3 --virt-ram=250
when run koan in my laptop, as follows:
# koan --virt --profile=test1-profile --server=136.145.116.114
i got the next output:
- processing profile: test1-profile
- fetching configuration for profile: test1-profile

ok, looks the parameter "--virt-ram=250" is a bad idea, i remove the
profile and create another one with no "--virt-ram" because default value
is 512, so, according to message looks enough.
I run again the koan command again and i got the next output:

Any suggestions? thanks a lot!
