Good afternoon, I have resolved the problem. Domo was trying to use the network Controller. Fixed it by using, /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:44:00.0)(0000:44:00.1)(0000:45:00.0)(0000:45:00.1)" reboot xl pci-assignable-list Xen Orchestra now allows PCI Networking Card to Pass-Through the VM. Regards

@jbamford So yes no dynamic memory there. Perhjaps an issue with the Citrix guest tools but never seen this reported.

You can open an issue on XCP-ng repo here: https://github.com/xcp-ng/xcp/issues Just check before if you can already have the temps from the dom0

@danp Okay that's great. I was just making sure. Thanks for your reply. Jack

@olivierlambert Ok cool, iSCSI is on its own Network on a Direct connection with Multipathing. In the past i have had problems with VMs going in Read Only Mode. Thanks for your reply.

@olivierlambert Just a update, I have moved from the Single Socket Server to the Dell R710 with 128GB of RAM successfully all VMs are working I have also updated to 8.2

@olivierlambert Hey i have another question, If i run the VM on the second Server does it matter if the RAM is the same althought CPUs are the same? Make and Model of the RAM or can that cause a problem? Another question if i have Host 2 online and i run different VMs on each of the host meaning Mail and Web Server on one host and Cloud Storage Server on the other using the same iSCSI storage can this be done by adding a second host to XO? or could it be possible to combine both servers into 1 for more Memory? Cheers. Jack.
