After upgrading my ovirt to 3.6 and configuring my host usb passthrough again. My vm is unable to start with the following error message: VM methub is down with error. Exit message: Node device not found: no node device with matching name 'usb' The host is running Centos 7 x86_64 Any ideas?

I am now getting this when I try to start it: VM methub is down with error. Exit message: Hook Error. To get the hostusb setup I did: engine-config -s "UserDefinedVMProperties=hostusb=^0x[0-9a-fA-F]{4}:0x[0-9a-fA-F]{4}$" ovirt-engine restart and the host has the usb hooked installed. But when I go an add the custom property "hostusb" the vm wont start. Again this is on oVirt 3.6 Centos 6.5 x86_64 and a host of Centos 7 x86_64 Any ideas? TIA!

I'm not sure how hostusb hook and proper hostdev solutions work together, could assigning the device through the more robust 'hostdev passthrough'[1] feature work for you? [1] http://www.ovirt.org/develop/release-management/features/engine/hostdev-pass...

Hi Fernando, in 3.6 to pass an host USB device to a VM you don't need an hook as it is now standard in the system. But if you have vdsm from 3.6.6 it doesn't work because of a bug. It has already been corrected and if you update vdsm* to 3.6.7rc it will work. I had the same problem but now it's OK. Going to the administration portal after the upgrade you should see your USB device in the "Host devices" tab of the "Host"; if it isn't there clik "Refresh Capabilities" and it should come up. Then you go to "Virtual Machines", select your VM, then "Host devices" and "Add device" and you're almost there. I learned this thanks to something posted in this list and probably a bugzilla too but I'm unable to find it ATM. If you see references to IOMMU ignore them unless you need to expose a PCI device. HTH, Giorgio.
Giorgio, Thanks for your reply. Where can I get vdsm from 3.6.7* for my host? Thanks again!
