Xen users - May 2010 - Guest kickstart installation and guest autostart

I have installed xen-3.4.2-2.el5 on CentOS 5.4 64bit OS

I encounter two problems : -
1) How to use kickstart with virt-install to auto-install Linux guest?

I use the following command to do installation

virt-install -p --name=test
--locationhttp://ftp.cuhk.edu.hk/pub/Linux/centos/5.4/os/i386--file=/dev/VolGroup00/test1
-r 4096 -x="ip=1.1.1.1 netmask=255.255.255.
dns=8.8.8.8 gateway=1.1.1.254 ks=http://2.2.2.2/ks2.cfg"

However, the installation startup can not get the IP address and go into
DHCP.  After timeout, I need to input IP address and installation will
proceed and get the kickstart config.
Any suggestions?

2) How to auto start the guest DomU after Dom0 reboot?
After I have installed the guest DomU through virt-install, I want to make
this DomU auto start in next Dom0 reboot.  After I type
virsh autostart test
It return the following errors:
error: Failed to mark domain test as autostarted
error: internal error sexpr2string failed

Any suggestions?

couple of things wrong there. probably some typo (like netmask), but
there''s also something that shoudn''t be there (like
"=" after -x). Try

virt-install -p --name=test
--location=http://ftp.cuhk.edu.hk/pub/Linux/centos/5.4/os/i386 --disk
path=/dev/VolGroup00/test1 --network bridge=br129 -r 1024 -x "
ip=192.168.129.222 netmask=255.255.255.0 dns=192.168.17.15
gateway=192.168.129.1 ks=http://2.2.2.2/ks2.cfg"

adjust network parameters according (including bridge) to your setup.
Also from another session on dom0, try running "xm list -l test". Look
for the line that says "method=http:// ...." and see if the complete
arg line makes sense (i.e. no extra "=" or other characters)

Not sure. Probably virsh bug.
The long way would be to do something like
- xm shutdown test
- xm list -l test > test.sxp
- edit test.sxp, look for on_xend_start and on_xend_stop
- xm delete test
- xm new -F test.sxp

FWIW I still prefer old-style config file, and creating symlinks in
/etc/xen/auto :)
