Thank you for asking this question on the **Microsoft Q&A Platform. **
It will depend on some details of the location of the VMs.
- If the Linux VMs are in Azure, from the Azure Site Recovery portal you can add all VMs.
- If the Linux VMs are on-premises and your replication environment is with VMware, from the Azure Site Recovery portal where you discover the VMs of your Center, you can add the VMs (previously you had to add the Linux credential in your Replication server)
- If the Linux VMs are on-premises and your replication environment is with physical servers, you have to add the IP (the Azure site recovery) and VMs credentials (In your replication server).
Here is some documentation that you can review, in case you don't already do it:
- Automate Mobility Service installation
- About the Mobility service for VMware VMs and physical servers
- Tutorial: Set up disaster recovery for Linux virtual machines
- Deploy Azure Site Recovery replication appliance - Modernized
I hope this helps!
