Vsphere Xfer failed "DEVICE_ALREADY_EXISTS"

[olivierlambert]

Is this VM had any specific configuration? Like multiple CD drive or something?

[jebrown]

no nothing special,
windows 2019 datacenter server with 3 drives 1GB, 60GB, 80GB no other drives or passthrough devices mounted.
I've moved several others with the exact same configuration and this one was in process when we had a network failure a few weeks ago... made it to about 30% complete at that time. Now when I try, it tells me it already exists but I cannot find where its located. I checked my shared SR (iscsi) looked in XOA under vm's and checked xcp-ng host to see if it was listed.

XCP-NG V8.3
XOA V5.100.2

I wonder if it's creating a device at the same position twice or something. IIRC, this error is raised when you try to create a VIF or a VBD at the same device position (device ID).

What's your 1GiB drive?

@florent any idea why?

[Danp]

How many network interfaces are defined on this VM?

[jebrown]

@olivierlambert the 1G drive is set up for some software licensing we have.

@Danp theres 10 VIF on that one

[Danp]

@jebrown For now, there is a limit of 7 network interface on a VM on XCP-ng/Xen Orchestra.

[olivierlambert]

10 VIFs could work but not out of the box, that's the issue. Try to remove some VIF and try again the import

[jebrown]

That was the issue! Thank you! I reduced it to 6 and the transfer is now running......... Will there be support for more than 7 VIF's or is there a way to add more than 7 now?

[olivierlambert]

You can add more via the CLI, see https://docs.xcp-ng.org/appendix/cli_reference/#vif-create

[jebrown]

Will adding by CLI cause any issues with migrations or backups?

[olivierlambert]

No it shouldn't.

Ok, Thank you!
