Re: [Xen-users] Xen 4.11 failed to start with more 4 NICs

[Reeve Yang <reeve.yang@xxxxxxxxx>]

Forgot to mention, I have tried to set:
device_model_version = 'qemu-xen-traditional'

Now the qemu-dm-sslv.log shows:
domid: 128
Too Many NICs

By the way, I have plenty of physical RAM and allocate 24G to this VM:
memory = 24576

Thanks for the help in advance.
