Hello!
Van egy jo kis gep, amin Wheezy van xen-nel (kinomban mar
backportos, 3.13-as kernellel).

Van rajta egy virtualis gep, aminek oda szeretnem adni az usb
portokat. Mar egy csomo mindennel probalkoztam, de nem akar
mukodni, a virtualis gep inditasakor mindig ezt kapom:
# xm create /etc/xen/windows-xp.cfg
Using config file "/etc/xen/windows-xp.cfg".
Error: (22, 'Invalid argument')
# grep iommu /etc/default/grub
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=512M iommu=1"
Az iommu=1 helyett mar probaltam az "iommu=pass-through" es az
"iommu=dom0-passthrough" opciokkal is, de ugy sem mukodott.
# grep pci /etc/default/grub
#GRUB_CMDLINE_LINUX="ipv6.disable=1
xen-pciback.hide=(0000:00:14.0)(0000:00:1d.0)"
GRUB_CMDLINE_LINUX="ipv6.disable=1 xen-pciback.hide=(00:14.0)(00:1d.0)"
Mind a ket variacioval probalkoztam mar...
# cat /etc/modprobe.d/xen-pciback.conf
options xen-pciback passthrough=1
A xen-pciback es a pci-stub modulokkal is megprobaltam,
termeszetesen kulon-kulon, reboot volt a probalkozasok kozott,
hogy tuti "uresen" induljon minden...
# cat usb_hozzarendeles_xen-pciback.sh
#!/bin/bash
modprobe xen-pciback
echo "0000:00:14.0" > /sys/bus/pci/devices/0000\:00\:14.0/driver/unbind

Barmelyik fenti szkriptet is futtatom, ezt kapom:

Aminel FLReset+ van, az ez:
00:03.0 Audio device: Intel Corporation Haswell HD Audio Controller (rev 06)
Igy ne is varjam, hogy oda tudom adni az usb-t a virtualis
gepnek?
# xm dmesg | grep -i enable
(XEN) Intel VT-d Snoop Control not enabled.
(XEN) Intel VT-d Dom0 DMA Passthrough not enabled.
(XEN) Intel VT-d Queued Invalidation enabled.
(XEN) Intel VT-d Interrupt Remapping enabled.
(XEN) Intel VT-d Shared EPT tables not enabled.
(XEN) I/O virtualisation enabled
(XEN) Enabled directed EOI with ioapic_ack_old on!
(XEN) HVM: ASIDs enabled.
(XEN) HVM: VMX enabled
Gondolom, hogy azert nem mukodik, mert nincs passthrough.
De vajon miert nincs? Mi az, ami miatt nincs? Elvileg az i7-es
proci tudja.
