Configure a SLES VM for Azure Site Recovery

To configure a VM for Azure Site Recovery we’ll need to configure the Microsoft Azure Linux Agent and enable the console. The VM will automatically get the DHCP network settings that it will need to get an IP from Azure.

First, add the repository and install the agent:

SLES 12 SP3:

zypper addrepo https://download.opensuse.org/repositories/Cloud:Tools/SLE_12_SP3/Cloud:Tools.repo
zypper refresh
zypper install python-azure-agent

SLES 12 SP4

zypper addrepo https://download.opensuse.org/repositories/Cloud:Tools/SLE_12_SP4/Cloud:Tools.repo
zypper refresh
zypper install python-azure-agent

SLES 15

zypper addrepo https://download.opensuse.org/repositories/Cloud:Tools/SLE_15/Cloud:Tools.repo
zypper refresh
zypper install python-azure-agent

SLES 15 SP1

zypper addrepo https://download.opensuse.org/repositories/Cloud:Tools/SLE_15_SP1/Cloud:Tools.repo
zypper refresh
zypper install python-azure-agent

SLES 15 SP2

zypper addrepo https://download.opensuse.org/repositories/Cloud:Tools/SLE_15_SP2/Cloud:Tools.repo
zypper refresh
zypper install python-azure-agent

Then enable automatic updates for the agent:

vi /etc/waagent.conf

Go to AutoUpdate.Enabled and enable it. It should look like this:

# AutoUpdate.Enabled=y
AutoUpdate.Enabled=y

Restart waagent and enable it:

systemctl restart waagent.service
systemctl enable waagent.service

Enable the serial console, to be able to access the VM even without connection from Azure: 

systemctl start serial-getty@ttyS0.service
systemctl enable serial-getty@ttyS0.service

ASR Kernel modules fail to load while installing the Mobility Service (VMware) – Azure

If some kernel modules fail to load (such as in the example below) while installing the Mobility Service agent, please check:

  • If the kernel is supported in your Configuration Server version
  • If secure boot is enabled
#EXAMPLE using SUSE 15 SP2
exampleserver0:/tmp/ASR # sudo ./install -d /usr/local/ASR/ -r MS -v VmWare -q
All product pre-requisties are met.
Generating the certificate.
[...]

Filter driver kernel module is not loaded. Attempting to load it, please wait...
insmod /lib/modules/[kernelversion]-default/kernel/drivers/char/involflt.ko 
Filter driver could not be loaded successfully.
Check the log file /var/log/ua_install.log for detailed diagnostic messages or installation success/failures...
Vx agent installation exit code : 208.
Check the log file /var/log/ua_install.log for detailed diagnostic messages or installation success/failures...
Installer exiting with code: 208

Check the following page to see if the kernel version is supported:

https://docs.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix#ubuntu-kernel-versions

If it’s supported try launching the following command: 

mokutil --sb-state

If it’s enabled you should get something along the lines of: 

SecureBoot enabled

Please note that SecureBoot is not supported at the moment with VMware DR in ASR:

https://docs.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix#storage

To disable SecureBoot proceed as following:

  • Click on the virtual machine in vSphere (or vCenter)
  • Shut down the VM
  • Click on Edit Settings
  • Go in VM Options, then Boot Options
  • Deselect the Secure Boot check box
  • Click on OK
  • Start the VM
