Note: I have my RHEL5 Dump in /rhel5/Dump
cobbler distro add --name=rhel5 --kernel=/rhel5/Dump/images/xen/vmlinuz --initrd=/rhel5/Dump/images/initrd.img
This ran good. Then I did the following:
cobbler profile add --name=redhat5x --distro=rhel5 --kickstart=/rhel5/Dump/ks.cfg --virt-file-size=2 --virt-ram=128
cobbler system add --name=00:16:3E:5F:93:6A --profile=""
Okay Now I exported my /rhel5/Dump via NFS. Here's cat /etc/exports
/rhel5/Dump 10.1.1.0/255.255.255.0(rw,sync,no_root_squash)
For the sake of convience I am also posting my /rhel5/Dump/ks.cfg and /etc/dhcpd.conf
cat /etc/dhcpd.conf

I don't know what happened during the ballon but it didn't created the virtual machine I was expecting.
One more thing I would like to through light on is that I have configured a virtual dummy0 network interface which is bridged to xenbr1. Here's my ifconfig(not shown are the xen virtual interfaces):
dummy0 Link encap:Ethernet HWaddr F6:42:E2:23:B6:57

All my xen related network stuff is handled by dummy0 and it is then masqureaded to eth1. I think there is problem with /etc/dhcpd.conf regarding eth1 and dummy0. I am not getting it.
Please through some light.

Hi,
I am trying to configure cobbler to configure my xen virtual machines. I tried to import the installation tree of rhel5 from cobbler using the command:
cobbler import --mirror=/rhel5/Dump/ --mirror-name=rhel5
It ran for sometime mirroring my rpm's and in last it ended up with this:
sent 2597509927 bytes received 50280 bytes 8644127.14 bytes/sec

I don't know what this is all about. But when I ran cobbler report it showed me this:
[root@server cobbler]# cobbler report

That means it has created the distro and profile part. Is that perfect or something is missing.
Please help.
