Description of problem: Only xen_vnif 4.7 PV-Lib (smp) module on X86-64smp AMD based machine host loaded. Version-Release number of selected component (if applicable): 0.1-10.el4 How reproducible: Unknown at this time Steps to Reproduce: 1. download modversions and kmod-xenpv-smp for RHEL 4.7 from RHN 2. install RPMs on guest, change modprobe.conf's eth0 3. restart guest Actual results: Found the following in the /var/log/messages Aug 6 19:45:23 ra-vm5 kernel: XENBUS: Device with no driver: device/vbd/768 Aug 6 19:45:23 ra-vm5 kernel: XENBUS: Device with no driver: device/vbd/5632 Aug 6 19:45:23 ra-vm5 kernel: XENBUS: Device with no driver: device/vif/0 Aug 6 19:45:23 ra-vm5 kernel: kobject_register failed for xen-platform-pci (-17) Aug 6 19:45:23 ra-vm5 kernel: Aug 6 19:45:23 ra-vm5 kernel: Call Trace:<ffffffff801edf1a>{kobject_register+60} <ffffffff8024f8ec>{bus_add_driver+80} Aug 6 19:45:23 ra-vm5 kernel: <ffffffff801f8b94>{pci_register_driver+119} <ffffffffa010300d>{:xen_platform_pci:platform_pci_ module_init+13} Aug 6 19:45:23 ra-vm5 kernel: <ffffffff80151105>{sys_init_module+278} <ffffffff801102f6>{system_call+126} Aug 6 19:45:23 ra-vm5 kernel: Aug 6 19:45:23 ra-vm5 kernel: xen-platform-pci: No platform pci device model found Aug 6 19:45:23 ra-vm5 kernel: xen_balloon: Unknown symbol create_xen_proc_entry Aug 6 19:45:20 ra-vm5 modprobe: WARNING: Error inserting xen_balloon (/lib/modules/2.6.9-78.0.1.ELsmp/weak-updates/xenpv/0.1-10.el4 /xen-balloon.ko): Unknown symbol in module, or unknown parameter (see dmesg) Expected results: All 4 xen modules would have loaded. Additional info:
Assigned for triage.
RHEL4.7 has the pv-on-hvm drivers built into the (bare-metal, FV) kernel package. Thus, loading the kmod-xenpv-0.1.10-el4 package will result in the kmod-xenpv modules failing when you try to (forcibly) load them. the xen-vnif you are seeing is the one built-into the std kernel package now. Simply put, all you have to have are the proper modprobe.d/xen module for xen-vbd and the alias eth[x] xen-vnif entry in the modprobe.conf in order for the xenpv drivers to be used by the FV guest. So, unload the kmod-xenpv package & use the in-kernel xenpv(hvm) drivers. If you continue to have problem, either re-open this BZ, or open a new one with a more appropriate title &/or problem statement.
