Image Creation from Base Image
Hello, I was able to successfully capture a base image. I have added the image to the image group. However, when I try to make a reservation, or create a new image, It eventually fails. I watch the VM server and see that a new VM was started. It does start a new VM with the correct MAC addresses, but Redhat detects these changed MACs as new interfaces, and assigns them to eth2 and eth3. Consequently, they are not brought up, the machine never dhcp's, and the image fails to contact the vcl server. Should I delete the network persistence rules before capturing the image ? Regards, Q

RE: Image Creation from Base Image
I dealt with this issue of the network interfaces changing assignments in our
Ubuntu images.
For Ubuntu 9.04 and earlier:
Create /etc/udev/rules.d/90-persistent-net.rules file.
Contents:
SUBSYSTEM==net, ACTION==add, DRIVERS==?*, ATTR{type}==1,
KERNEL==eth*, OPTIONS=ignore_device
This prevents the device rules from assigning eth0 and eth1 different names
because the mac addresses don't match the original machine.
For Ubuntu 10.04 and later:
Instead of creating 90-persistent-net.rules file, create
/etc/init.d/udev-netrule script to remove
70-persistent-net.rules file on shutdown, so it doesn't exist when image is
captured.
Contents:
/bin/rm -f /etc/udev/rules.d/70-persistent-net.rules
Link to /etc/rc0.d/S10udev-netrule and /etc/rc6.d/S10udev-netrule.

That¹s great. Looking forward to the new release.
But how were you able to manage new images before?
Does the problem not exist in other Linux distros ?

RE: Problems in Ubuntu image creation
We are using Ubuntu images. I see the VCL trying to configure the RedHat-type
network files and failing to do so since those files don't exist in Ubuntu.
However in our case, the failures are harmless because we use DHCP, so I set
the /etc/network/interface file accordingly in the initial image, and it
doesn't need changing after that.
/etc/network/interfaces entries:
==
# The primary network interface
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet dhcp
==
I don't think the disk type error is related to Ubuntu, seems to be coming from
the vmware provisioning piece.
I also had to make the following changes in the Ubuntu images to prevent the
network interfaces from being given different device names each time, e.g.
eth2, eth3, etc.
For Ubuntu 9.04 and earlier:
Create /etc/udev/rules.d/90-persistent-net.rules file.
Contents:
SUBSYSTEM==net, ACTION==add, DRIVERS==?*, ATTR{type}==1,
KERNEL==eth*, OPTIONS=ignore_device
This prevents the device rules from assigning eth0 and eth1 different names
because the mac addresses don't match the original machine.

Instead of creating 90-persistent-net.rules file, create
/etc/init.d/udev-netrule script to remove
70-persistent-net.rules file on shutdown, so it doesn't exist when image is
captured.

Lei,
I was hoping someone actually using Ubuntu images would respond to this.
Here at NCSU, we aren't using Ubuntu images, but VCL should support them (at
least it did in the past). Did you select Ubuntu as the OS when capturing the
image?
It is also possible that the Ubuntu module may need to be updated.

Dear all,
I have to bother you again. I tried to create an Ubuntu image, but I
found some problems during the base image creation. Ubuntu uses
/etc/network/interfaces to manage networks, but I see VCL is still looking
for ifcfg-eth0 and ifcfg-eth1. Another problem was unable to determine the
disk type, which I am not sure if it is specific to Ubuntu.
Does VCL support Ubuntu image?
Thanks,
Lei Huang

Images and Connections
Hello, First of all, thanks for all your help so far. I have been able to create a base image, and create new images based on that. The trouble that I am having now is that when I try to connect to the newly created Linux image, the SSH session closes immediately. When I connect to that image directly on the console, I am able to connect using the credentials supplied by VCL. Any ideas on why that is happening ? Regards, Al Q
