If you tried installing RHEL 9 on Synology VMM , you probably hit this nightmare: Installer freezes waiting for multipath siblings of sda Kernel panic “Unable to mount root fs” Black screen forever I spent hours figuring this out. This guide will save you that pain and help you create a Golden Template so you only install once and clone forever. Why RHEL Fails on Synology VMM Synology VMM uses simplified KVM virtualization. RHEL assumes enterprise SAN storage and enables multipath disk detection by default. Synology presents a single virtual disk → RHEL thinks it’s a SAN disk → installer waits forever for extra disk paths → boot fails. The fix is simple once you know it. Step 1 — Create the VM with Correct Settings Create a new VM in Synology Virtual Machine Manager .
