Migrated Rocky Linux -8 VM from VMWare to XCP-ng and now will not boot

Hi Team
I am new to XCP-ng and am on the latest release.
Migrated Rocky Linux VM from VMWare to XCP-ng using the import option in XO and now will not boot.
It shows the initial rocky Linux banner for more than 3 minutes and finally comes to the root prompt and only command I can run is the list "ls -l"

Request the experts to guide me here.

@venkatm Which firmware is the VM using to boot, BIOS or UEFI? Are you ending up in the dracut emergency shell?

venkatm

Used UEFI for booting. This is a working VM in VMware platform.
Yes its going to safe mode

Hi.

Can you try to have a VM setup within XenOrchestra and then use Clonezilla to get the machine over?
Power down the Rocky Linux VM, boot from a Clonezilla ISO and do the same thing on a VM in XOA.

You should make sure to have at least the same or a little greater amount of storage on the new VM on XOA
as it was on the VMWare platform before starting the clone.

Just to have a fallback option in case the XOA import mechanism has a problem.

Best regards,
Marc

It's likely because your Rocky, during install, did not add the Xen PV drivers. For example in here, before migrating: https://docs.xcp-ng.org/installation/migrate-to-xcp-ng/#-from-kvm-libvirt

Plus one for Clonezilla here, has worked for me migrating Rocky from various hypervisors to xcp-ng.

@itservices tried it , disk was detected but copy of data failed and process ended in minutes.

Echoing what @olivierlambert mentioned. I migrated a number of Almalinux VMs and they too would not boot until adding the Xen PV drivers.

@venkatm

Did you try to match drive size from source to xcp-ng? That gave me issues before, when drives on xcp-ng was a bit to small.

@iLix The sizing of the VM in XCP-NG was bigger compared to the source
