Subject: [Xen-users] Problem creating xen paravirtual guest
Hi all,
I installed kernel-x86_64 2.6.32.26-174.1.xendom0.el6.
x86_64 on cent os 6 x86_64 and got xen-4.0.1 working on it. I have been able
to create full virtual systems with virt-install and virt-manager, but
when I tried creating paravirtual domu cent os 5 x86_64 I am getting the
following error:
ERROR Could not find a kernel path for virt type 'xen'
Domain installation does not appear to have been
successful. If it was, you can restart your domain
by running 'virsh start cent'; otherwise, please
restart your installation.

ValueError: Could not find a kernel path for virt type 'xen'
I created the virtual machine using virt-install using the following command:
virt-install -n cent5 -r 256 -l
http://mirror.centos.org/centos/5/os/x86_64/images/xen/ --disk
path=/home/aks/vm/cent.img -p
Hope you can help me out.
-------------------------------------------------
the http path is too deep. You can see that it find the ./images/xen directory
starting with your path above.
Use the --debug param to see the details.
I attempted the same thing here
