Trying this same import on a second pool again fails, this time I started with the master.

I exported the VM about 48 hours ago on an 8.3 pool that was fully up to date. When I tried the import yesterday, it failed. When I made the host physically holding the export the pool master, the import worked. I assumed the issue was just being the master or not. I now believe that was coincidental, not my actual problem because......

I completed a long copy over the internet overnight of the same export from 2 days ago. I scp'd it directly to a pool master. The pool master had 28 listed updates in XOA, so I did the simple yum update. It installed the updates, but then when I went to import the xva, I hit the same error again -

[10:07 hypervisor1 ~]# xe vm-import filename=/storage/exported.xva 
The import failed because this export has been created by a different (incompatible) product version

We're not doing anything with false DNS or security features that block access to the actual mirrors.xcp-ng.org.

Any ideas?

I experienced the same issue!

What I found was that just doing a "yum update" was not enough, though it was needed.

When I was initially getting the error, I was trying to import on a host that was not the master of the pool. After I designated that host as the pool master, the same command worked easily.

I had to do both the update and import on the master only.
