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=(:00:14.0)(: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...
