Hi,

I've run in to an interesting and annoying problem. I'm passing two DVB-S2 cards through to a windows 8.1 VM. Using the client without connecting to Vcenter it all works fine and the two cards attach ok. As soon as I set the host to be managed by Vcenter, attaching the cards comes with this error "PCI passthrough device ID (0x-73d3) is invalid".

I've googled lots but nothing is pointing me in the right direction.. I do not know why Vcenter is treating this differently to the .NET client?

Any suggestions? anyone else had this?

Cheers,

Chris
 
Wanted to add that as soon as I remove the host from vCenter, the passthrough devices pass through fine and the system boots. Adding the host back in to vCenter then retains the settings and allows web control... Strange stuff.

Has anyone noticed this in vCenter 6?
 
I posted in your other thread: I assume it is because it doesn't make sense to have PCI pass-thru in a multi-host situation.
 
Hey thanks rotor,

Yeah I did wonder that, but strangely since I'm now managing the cluster through the C# client attached to the vCenter instance, passthrough attached without error and the vm seems to have booted fine.
 
Ah I see. So vCenter via GUI client works fine, vCenter via Web client doesn't. I loathe the web client with a white hot passion, so I couldn't possibly comment. =)
 
You can happily configure passthrough with vcenter (web or fat client normally) - nothing to do with "not making sense". You use vcenter to manage every other individual host setting, passthrough is no different. This is just a bug/quirk with that card, i dont imagine its on the HCL for a start
 
Its just a tad weird that using the web client it fails with a different device id to the actual device, but using the fat client works fine. vCenter appears to be a necessary evil for creating somethings but at least the windows client can do what I need! And you're right, only the server is on the HCL list, not the pci devices.
