Instnace Hostname issue

Hi,

 

When creating instance, let's say I put test-vm.local. I create instance
using template that I make from iso installation. After vm running, when I
goes into OS it did not set hostname to test-vm.local. What do I need to fix
to settle this issue?

 

Thanks.

Hi,

When creating the template check that the hostname in /etc/hostname has been removed (file is blank)
Also check /etc/sysconfig/network for a hostname 

Regards
Glenn

Hi,

I'm try to do template from Centos 6.5. 

Step:
1. Create a VM.
2. Install VM using ISO.
3. Reboot VM after installation finish.
4. Login VM. Can ping other VM in ACS host.
5. Shutdown VM.
6. Create template A1 from ROOT disk of VM. Waiting until template available.
7. Create another VM using new template A1. Set hostname test-1.
8. Access VM (from template A1). Notice the hostname set early from ISO. Not the new hostname.

Before proceed to create new template, there are no hostname in /etc/hosts. Just localhost.localdomain. I have following the URL to create template.

Hi,

What OS are you using?
When your create the template from the ISO are you clearing the hostname and udev rules before make a template from the VM also clear the /etc/hosts file so there is only localhost addresses .

You can have a look at the following link 

http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.8/templates.html

Thanks
