Re: [Xen-users] can not unbind pci device, xen kernel, openSUSE
Hi, thank you for quick answer. You was right I missed the format. But I still have a problem. Continue the PCI unbind procedure the wiki says[1]: echo -n ".&checktime(0000,00,1,':')a.0" /sys/bus/pci/drivers/pciback/new_slot
and .. echo -n ".&checktime(0000,00,1,':')a.0" /sys/bus/pci/drivers/pciback/bind_cat In my openSUSE 11.2 there are no /sys/bus/pci/drivers/pciback directory. OK. I have /sys/bus/pci/drivers/pci-stub maybe this would be nice[2]:
continuing the procedure: echo -n ".&checktime(0000,00,1,':')a.0" /sys/bus/pci/drivers/pci-stub/new_slot -bash: new_slot: No such file or directory echo -n ".&checktime(0000,00,1,':')a.0" /sys/bus/pci/drivers/pci-stub/bindcat
-bash: bindcat: No such file or directory I get these messages ... Regards, Istvan [1] http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module

at this point:

i get an error message:
-bash: echo: write error: No such device
