Commvault supports automatically injecting Xen and Nitro drivers for Linux Guest VMs.
Supported Linux Operating Systems
-
Commvault supports automatic driver injection for the following versions of Linux, however guest VMs have to be from Red Hat distribution:
-
RHEL8
-
Oracle Linux 7
-
Oracle Linux 8
-
-
Kernel modules for the required drivers must be present in the guest VM's module directory (/lib/modules). If kernel modules for xen-blkfront or xen-netfront are not available, the script will fail.
Before running backup, you may be required to run a procedure for your guest VMs to ensure network connectivity in AWS. See, Ethernet Naming Convention.
Setup Requirements
-
Configure a Linux access node on the destination AWS hypervisor.
-
The Linux access node must be used as the access node.
Procedure
After all the data has been written to the restored volumes during HotAdd conversion jobs for Linux Guest VMs, driver injection will take place.
The driver injection process is as follows:
-
Attach the restored OS disk to the Linux access node.
-
Mount the restored OS disk.
-
Determine the list of drivers to be injected.
-
Run the driver injection script.
-
Unmount and detach the restored OS disk.
Known Limitation
If you are performing a cross-vendor replication to Amazon EC2 using HotAdd (for example, VMware to Amazon EC2), when doing a failback, be sure to have only a Linux access node on the source hypervisor (for example, the VMware hypervisor).
Options for Conversion to AWS
When submitting the restore, be sure to select the Linux access noode as the access node and HotAdd as the transport mode.
