Can't ssh or ping the VM's from outside. Can't access any external resource from inside the VM's (except as noted below)
I have seen this reported before, and I have had it and solved earlier, but now I'm stuck on a new installation. Environment: - Ubuntu Server 13.04 - Frontend with a NFS storage raid array - Hosts (3) - OpenNebula 4.2 - KVM - Using 802.1Q VLAN on the config Hosts and Frontend have a 10GB private network All also have a normal 1GB Network (public IP's) I can create VM from images downloaded from the Marketplace. I also created my own images and contextualized them using the Opennebula contextualization script. They all come up fast and well. I can connect to them via the Sunstone VNC interface. On the Ubuntu, VM's using the images I built, I can login and check the system. Same with the Marketplace ttylinux/debian images as the credentials are known. The problem is that I can't ping or ssh to any of them from outside. I can't access external resources from the VM's I'm able to login via Sunstone/VNC either. The settings, from the VM's I can login seem correct, I mean, ifconfig, route, etc. DNS and Gateway are define and correct. I use a 255.255.255.192 Netmask for my Public network, that also come in ok. I can ssh/ping other VM's running on the *same* host! But that is it. I had a similar issue on another installation, but can't recall how I resolved it. Had to do with the Context setting... I use the SunStone interface for all of this. This installation is almost identical, the only difference is the switch I use for the public network, this one uses a Cisco 3750 the older (and working) system uses a DLINK (both support VLAN's). I'm definitely doing something wrong. Opennabula is super easy and powerful but I can't see the issue! Any suggestions, recommendations will be appreciated! BTW, unrelated: the "CentOS 6.2 Server - kvm" image available on the Marketplace always errors when downloading. Best regards, Klimber
