Thus, the idea was to attach devices, PCI and USB, to VM and run another kernel there, yet retain "stable" kernel beneath resp. Host itself. Tested HW: * Kingston DataTraveler 4GB USB flash disk * Lifeview LV5TDLX DVB-T [RTL2832U] ~ aka uberUnsupportedCrapDevice :) * Leadtek Winfast DTV1000 S PCI ~ which have gained support in 2.6.33 Thank you all for help and have a nice day :) Zdenek PS: could somebody lend me a hammer - a bigger one :D -- Zdenek Styblik Net/Linux admin OS TurnovFree.net email: stybla@xxxxxxxxxxxxxx jabber: stybla@xxxxxxxxxxxxxxxxxxxxx -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
