Re: Obscure error when adding second vhost-scsi-pci device to VM

[George Diamantopoulos]

Never mind, I supplied the wrong wwpn for the new device... :-\

Hello all,

I'm getting the following errors when adding a second vhost-scsi-pci device to a previously functioning VM:

kvm: Error setting vhost-scsi endpoint
kvm: unable to start vhost-scsi: File exists

The relevant configuration (after adding the second device) is:

-device vhost-scsi-pci,bus=pci.0,id=disk-dbstor,bootindex=100,wwpn=naa.500140534697d220,num_queues=12,vectors=13
-device vhost-scsi-pci,bus=pci.0,id=disk-dbback,bootindex=101,wwpn=naa.50014052363e27f3,num_queues=12,vectors=13

VM used to start fine with just a single vhost-scsi-pci device and no other changes. Any hints as to what might be causing this would be greatly appreciated. Thanks!

Best regards,

George
