hi,
i want to enable vt-d in xen, but meet an error.
at first, i do all things as /xen-unstable.hg/docs/misc/vtd.txt
says.
grub : kernel /boot/xen-3.5.gz iommu=passthrough
module /boot/vmlinuz-2.6.18.8-xen pciback.hide=(02:00.0)(02:00.1)
hvm.conf :pci=[''02:00.0'',''02:00.1'']
(02:00.0 02:00.1 are my nics)
after reboot,there is no these two nics in ''ifconfig -a''
and when i start hvm, it is block on "PNP: PS/2 controller........"
at this time, i use ''xm pci-list hvm'' and got messages
0x04....
0x05.....
that seems pci devices have been passed to hvm.
but when i changed two nics to another pci device, it can be assigned to hvm
successfully.
grub : kernel /boot/xen-3.5.gz iommu=passthrough
module /boot/vmlinuz-2.6.18.8-xen pciback.hide=(00:14.1)
hvm.conf :pci=[''00:14.1'']
(00:14.1 GPIO)
any one can help me?thank you for advance!
