Installed Openstack Nova in RedHat Enterprise 6, can upload custom image, run instances, but can't ping neither ssh to VMs

Asked by Liang

I'm new to openstack cloud, but managed to install Openstack Nova in 2 RedHat Enterprise 6 by following documents in wiki, especially "http://wiki.openstack.org/NovaInstall/RHEL6Notes", I was able to custom made a RedHat Enterprise 6 image and uploaded, run instance and saw they show "running", but can't ssh or ping the VMs, of course, I did the euca-authorize thingy. Also, I can't seemed to be able to deploy VMs to 2nd node (computing node) and I ran nova-compute on both controller and computing node.
Following are my configuration files, hope someone can enlighten:

We have a problem with dnsmasq in that build. Please use injection of network settings as temporary workaround.
We'll update our blog once that problem will be resolved. You can find it at http://openstackgd.wordpress.com/

Hi, Andrey,

Thanks for your pointer, my openstack nova is working in RedHat Enterprise 6
environment.
I'd like to find out where I can find instruction on installing openstack
dashboard to RedHat Enterprise 6, do you have information about such?
I'll check the blog to watch the new release of dnsmasq issue.

Thank you again for your great help.

Wang

sorry, what does that mean "injection of network settings"?

amy,

That means during an instance firing up host system mount instance's file system and put networking data (IP address, network mask, gateway's IP and DNS server IP) into some file (/etc/sysconfig/network-scripts/ifcfg-eth0 for Fedora and Fedora-based distros).

Hi,
Few questions after I got nova running in my RHEL6 environment:
1. With the above settings, when I run instance, it only allow me to run 10 instances, after that, it gives me an error:
"euca-run-instances ami-zhgo1eyb -t m1.small
InstanceLimitExceeded: InstanceLimitExceeded: Instance quota exceeded. You can only run 0 more instances of this type."
With the --network-size=32 in nova.conf, I thought I can run instances for up to 30, I think I get this wrong.
2. I can tell the image type have following: m1.tiny, m1.small, m1.medium, m1.large. maybe more, can someone point me to where I can find out how many types are available?
3. after the computers restarted, I lose all the running instances, even though I can find them in mysql db and /var/lib/nova/instances, but I can't no longer show them in euca-describe-instance command even I use virsh to manually start them.

Thanks in advance for any help.

try nova-manage project quota

This shouldn't be happening with current trunk. Perhaps the rh packages are a little behind.
