@Danp Yes, I am using the old one. I think I can overcome this by passing path and updating xo. Thank you.

But I was able to get the job done by exporting the VHD file.

xe vdi-list
xe vdi-export uuid=33a94644-ef92-4ebe-8aef-77525c5931d9 filename=filename.vhd format=vhd
OR
curl -u 'root:pass' -X GET "192.168.1.100/export_raw_vdi?vdi=33a94644-ef92-4ebe-8aef-77525c5931d9&format=vhd" -o filename.vhd

@enes-selcuk The error is telling you that you're host doesn't have enough Memory to actually start the VM.

Is this VM from an OVA and being imported (or has been imported?)

If you have XO or XOLite installed, you can try to reduce the amount of Memory assigned to the VM and start it then.

@enes-selcuk odd...

Sorry I can't be of more help with this than... when you're VM is starting I think the boot key is the Delete key, maybe there is a keyboard difference?

I get the following error. can you help me.@AtaxyaNetwork @DustinB
xe-linux-distribution.service: Control process exited, code=exited status=203

Hello,

Can you with a support client for XCP-ng? (like XO). You can also use xe to see the output.

Can't help with your issue, but wanted to point out that the article you linked only references Xenserver 6.X, so may not be applicable to newer versions.

When I issue the shutdown command to the host / physical machine via xoa, the process does not occur. it gives an error.

Stop

no hosts availeble

Looks like this documented issue: https://xcp-ng.org/docs/troubleshooting.html#ubuntu-18-04-boot-issue (found by looking up "ubuntu" in the docs)

During VM export, the ssh connection is gone and the result is frustrating. the disk of the virtual computer does not appear at all.
Xcp-ng 8.0 use. I think he sent the disk to eternity.

@enes-selcuk Did you find a setting that works best w/ Dell servers?

I have a Dell R640's which I'll be using for LAMP/LEMP vm servers and was wondering what are the best settings to use in Dell Bios and if there are any changes I need to make on the xcp-ng host?
