Good evening friends,

I'm migrating a handful of VMs over from Xencenter 7.6 to XCP-NG Center 20.04. I'm running into a spot of trouble with a handful of VMs - they migrate over fine, but will not automatically start. Moreover, when I try to manually start them, they immediately shut down after hitting the "Boot device: Hard Disk - success" screen:

A couple of troubleshooting thoughts:

1.) The majority of VMs that appear to have this issue appear to be running Ubuntu 14.04. When booting in, if I manually access the GRUB menu and choose a Linux kernel that is older than 3.13.0-39, it does boot without issue. However choosing anything newer than that fails to boot.

2.) I've tried a handful of Ubuntu 16 and 18 VMs, and those appear to boot without issue. However one Ubuntu 16 VM I tried booting fails with the same issue, so I can't say for sure whether other VMs will fail as well.

3.) All VMs boot with BIOS and I did check these settings in XOA.

4.) The hosts have different CPU vendors (Intel -> AMD EPYC) but I doubt this is the issue because the VM does boot on the older kernel (as mentioned above.)

Has anyone ran into this issue? Any thoughts/clarifications I can offer?

Thanks in advance!

So it looks like the warm migration of the first VM I tried migrating works, but after trying to migrate another VM, I'm getting a new error message: "Warm migration: task has already ended"

Is there any particular process that I'm missing to mark the first VM as successfully migrated?

**edit: Maybe I'm just impatient because after waiting another couple of minutes it looks like it's migrating OK.. LOL

Thanks y'all! I updated to the latest versions and it looks like the functionality is working now. I still need to test it but it does seem a bit slower than expected although I'm not sure if that's because I'm still on 1G connections. Time to do more testing...

Thanks again!

Hi all,

Trying to warm migrate a VM from one host with a XenCenter 7.6 hypervisor to another host with XCP-NG 20.04.1 using XOA Community Edition's web interface and I'm getting the error "Method not found: vmwarmmigration" when doing so.

The hosts have different CPU vendors but there should be enough storage space on both. They can also ping each other.

The logs do not appear to be loading properly either.

Is there anything I'm missing here? I'm relatively new to XCP-NG so any help is appreciated!
