Xen project Mailing List

Hi,

Please help: I tried to create a DomU with PCI passthrough. I don't know hoe to proceed.

The last output is:

pcifront pci-0: Installing PCI frontend
pcifront pci-0: Creating PCI Frontend Bus 0000:00
pcifront pci-0: claiming resource 0000:00:00.0/0

I tried to login VM with
xm cosole 6 but nothing happened.

linux:~/Desktop # xm console 6

The following is the detail info.

Thanks.

Vic

I have config file:

-------------------------------------------------

kernel = "/boot/vmlinuz-3.0.1.stk64"

#ramdisk = "/boot/initrd-xen"

memory = 512

vcpus = '2'

pci = ['02:00.0']
name = "xen-vm1"
root = '/dev/xvda1 ro'
disk = [
         'file:/home/domains/nvidia/XenGuest1.img,xvda1,w',
        ]

-----------------------------------------------------------
after xm create -c nvidia.cfg

I can see
linux:~/Desktop # xm list
