Re: [libvirt] QEMU/KVM support for non zero PCI domain

Hi Laine, Here are the information you have requested: 1) What is your Linux distro and version RHEL 6.1 - 2.6.32-131.0.15.el6.x86_64 2) what version of qemu/kvm do you have [root@uv2 qemu]# /usr/libexec/qemu-kvm -version QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2), Copyright (c) 2003-2008 Fabrice Bellard 3) what version of libvirt? [root@uv2 qemu]# libvirtd --version libvirtd (libvirt) 0.10.2 4) Does libvirt actually get to the point of running qemu or kvm command? 5) If the answer to (4) is "yes", can you send the qemu command that is generated (it will be at the end of /var/log/libvirt/qemu/${guestname}.log) LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -name UV2-VM1-test1 -S -M rhel6.4.0 -enable-kvm -m 8192 -smp 4,sockets=4,cores=1,threads=1 -uuid e2428c26-f06a-b03c-c8d5-c528f2e85596 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/UV2-VM1-test1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/UV2-VM1-test1.img,if=none,id=drive-ide0-0-0,format=raw,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=23,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:51:5f:5f,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 127.0.0.1:0 -vga cirrus -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device pci-assign,host=02:00.4,id=hostdev0,configfd=24,bus=pci.0,addr=0x6 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 char device redirected to /dev/pts/2 get_real_device: /sys/bus/pci/devices/0000:02:00.4/resource: No such file or directory qemu-kvm: -device pci-assign,host=02:00.4,id=hostdev0,configfd=24,bus=pci.0,addr=0x6: pci-assign: Error: Couldn't get real device (hostdev0)! qemu-kvm: -device pci-assign,host=02:00.4,id=hostdev0,configfd=24,bus=pci.0,addr=0x6: Device 'pci-assign' could not be initialized 2013-04-15 19:38:31.454+0000: shutting down ******************** As you can see, I cannot run qemu command directly from libvirt.

I knew it existed, but I've never seen hardware that actually had multiple domains. Huh. I would have figured it would be stopped by libvirt first, as libvirt's PCI address parsing currently rejects anything with domain or bus that isn't 0. That doesn't sound like a libvirt error message though, which implies that, at least for host-side PCI addresses, libvirt is doing the right thing, and the error is coming back from kvm. A few questions: 1) What is your Linux distro and version 2) what version of qemu/kvm do you have 3) what version of libvirt? 4) Does libvirt actually get to the point of running qemu or kvm command? 5) If the answer to (4) is "yes", can you send the qemu command that is generated (it will be at the end of /var/log/libvirt/qemu/${guestname}.log) -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
