Connecting sandbox to Azure for cloud burstin fails

Community Support

Setting up the OpenNebula sandbox with no issues.

Have an Azure account set up, generated the certificates, uploaded the .cer file etc to Azure subscription, modified oned.conf, az_driver.conf with subscription id and path to my cert etc, and modified VM templates.

Now, registering an azure region as a host in opennebula, it shows up under Hosts in sunstone, but with an error. Tailing oned.log gives the following:

So, something goes wrong connecting to azure, probably something with the cert. Google searches points to some Ruby issues as well. Anyone have succeded wiith this?

Replying on my slef here. Found that a spelling issue in az_driver.conf caused the issue. Now in connects and monitor, and I can from bash list wild VM’s and import those running VM’s from my Azure into open nebula.

However, I fail to deploy a new VM in Azure. My template:

CONTEXT = [
NETWORK = “YES”,
SSH_PUBLIC_KEY = “root[SSH_PUBLIC_KEY]” ]
CPU = “1”
DESCRIPTION = “Launches an t2.micro Ubuntu”
DISK = [
IMAGE = “ttylinux” ]
FEATURES = [
ACPI = “no”,
APIC = “no” ]
GRAPHICS = [
LISTEN = “0.0.0.0”,
TYPE = “VNC” ]
MEMORY = “1”
NIC = [
NETWORK = “cloud” ]
PUBLIC_CLOUD = [
CLOUD_SERVICE=“MatsCloud”
IMAGE = “b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu-14_04-LTS-amd64-server-20140606.1-en-us-30GB”,
INSTANCE_TYPE = “Small”,
LOCATION = “north-europe”,
SSHPORT = “2222”,
TCP_ENDPOINTS = “80”,
TYPE = “AZURE”,
VM_PASSWORD = “mypass”,
VM_USER = “azuser”,
WIN_RM = “https” ]
SCHED_REQUIREMENTS = “PUBLIC_CLOUD = YES”

sched.log shows that it goes to the correct host(north-europe), but deploy fails. From oned.log:

Trying to find that exit code 255 as I believe it is Azure response. Right?

And yet again I answer on my own issues:-)

Thing is, the ntpd is NOT installed in the sandbox as default, and in virtualbox causes a drift in time, thus causing the issue.

Yum install ntp and service start ntpd solved the issue.

For next release of Sandbox, ntpd should be included.

THANKS for letting us know!

Just filled an issue for next release
