Problem creating VM using CentOS 6.4 template
Dear all,
I am using CloudStack 4.1.0 with KVM hypervisors. I tried to create CentOS
6.4 template by installing a CentOS 6.4 VM from ISO, and then save the root
disk as a KVM template.
However, when I tried to create a VM using the template, while the server
was created, the network is not working because the new VM activates
different ethernet port (eth1 instead of eth0) while on the original VM,
only eth0 was configured.
If I tried to configure the network settings (DHCP) on both eth0 and eth1
and then recreate the template, the new VM based on the template will
activate eth2 instead.
Anyone having similar problem and have found a solution to this problem? I
only have this issue with CentOS 6.4, I don't have any issues using CentOS
5.9 or Ubuntu 13.04 / 12.04.2.
Looking forward to your reply, thank you.
Cheers.

Delete the 70 rule, before finishing the template, in the /etc/udev/rules.d which persists the MAC address to eth0 and so on.
That's actually quite common and cloud stack unrelated. (Please verify path, I'm on the road)

Dear Bjoern, Shankerbalan, Marty and all,
Thanks! Managed to create a working template by:
(1) Commented out the line on /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x8086:0x100e (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="06:12:f8:01:12:5f", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
(2) Delete the line containing the MAC address on
/etc/sysconfig/network-scripts/ifcfg-eth0.
Thank you for your help!
Cheers.

Hi Indra,
I pushed some documentation for this into 4.2 last night. I have attached a
snippet of the PDF.

Hi Indra,
Have you cleaned up ifcfg-eth MAC address definitions and /etc/udev/rules.d/70-persistent-net.rules files before creating the templates? I have seen this issue if there are stale MAC addresses defined to ifcfg-eth0.
Regards.
