   Different option of quick virt-install PV DomU (with xen-ified kernel on ISO image)  via local HTTP mirror :-

# dd if=/dev/hde of=/etc/xen/disks/CentOS5.iso
# dd if=/dev/zero of=/etc/xen/images/CentOS5.img  bs=1024k count=12000
# chkconfig httpd on
# reboot
# mkdir  -p /var/www/html/rhel
# mount -o loop  /etc/xen/disks/CentOS5.iso  /var/www/html/rhel

In other words , create local HTTP mirror via local Apache Server

Run :-
# ifconfig
to find out your IP address (IP-Dom0) and run

# virt-install -n CentOS5PV -r 1024  -p  -f /etc/xen/images/CentOS5.img \
      -l   http://IP-Dom0/rhel

Virt-install provide you to options for location (on CentOS 5.X and Fedora 8)
1. NFS shared directory  ( --location nfs:IP:/dir1)
2. Local or remote HTTP mirror  ( --location http://IP/dir1)

Hmm, someone told me the other day that I should be using xen-tools and rinse, and NOT virt-install (see http://lists.xensource.com/archives/html/xen-users/2009-03/msg00742.html).

So which one should I use and why? And if I should be using virt-install, can someone please take a look at my initial problem that I still haven't fixed in the above thread? :p

Cheers,

Andrew

Sure,  getting this rinse bug fixed you'll get login to DomU.
I just cannot understand why old fashioned style of PV DomUs
setup ( with all kind of debootstrap's fun) seems so attractive on the system having virt-install ready to go.
Please, advise. Where i am wrong ?

Boris.

Yup. Put it before the line "1:2345:respawn:" ...
I think what happens is your domU boots succesfully, but it does not
display any login prompt on console (which is xvc0).

Oh and you should also add "xvc0" to /etc/securetty.
