When i try to start a VM with both a virtio block device and a virtio network device, i get this error message: Error starting domain: internal error process exited while connecting to monitor: char device redirected to /dev/pts/0 qemu-system-x86_64: -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:60:70:68,bus=pci.0,addr=0x3: PCI: slot 3 function 0 not available for virtio-net-pci, in use by virtio-blk-pci qemu-system-x86_64: -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:60:70:68,bus=pci.0,addr=0x3: Device 'virtio-net-pci' could not be initialized Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/engine.py", line 959, in asyncfunc vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 1114, in startup self._backend.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 362, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error process exited while connecting to monitor: char device redirected to /dev/pts/0 qemu-system-x86_64: -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:60:70:68,bus=pci.0,addr=0x3: PCI: slot 3 function 0 not available for virtio-net-pci, in use by virtio-blk-pci qemu-system-x86_64: -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:60:70:68,bus=pci.0,addr=0x3: Device 'virtio-net-pci' could not be initialized and the guest doesn´t start.

Can you attach the (anonymised if necessary) xml fiel for the domain? It might not be as simple as it appears :/
Hi Diego, i´ll attach the XML for the VM. I have successfully installed the guest OS with the virtio block device, after that i tried to add the virtio-net device which led to the error.
Created attachment 268621 [details] XML file for the VM in question
Created attachment 268625 [details] XML file for the VM in question Posted the wrong XML beforehand. This is the correct one.
Terrific, this looks definitely like an upstream bug, but not sure if it's virt-manager's or libvirt's properly.. As a workaround, add <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> within the definition of the block/disk device.
Hm, editing the XML with "virsh edit vmname" doesn´t help. Everytime i modify the XML, it seems to get reverted the moment i leave the editor. Trying to start the VM still gives me the error message.
Okay, i got around this by changing the slot number within the definition of the virtio-net device from 3 to 5. Network device within the VM is working fine.
Just saw the same issue with libvirt-0.8.7-r1 and qemu-kvm-0.13.0-r2. So more than likely its an issue with qemu-kvm instead of libvirt.
Looks like PCI slot 3 is where it ALWAYS wants to put the virtio SCSI controller inside the guest so no other device can live there.
Yep, there's a bunch of reserved PCI slots in KVM. This is a limitation of KVM and the slots that are reserved vary from pc-0.12 to pc-0.13, which explains why previously you didn't have the error and now you do. The patchset to fix this can be seen: http://article.gmane.org/gmane.comp.emulators.kvm.devel/71594 It will likely make it out in qemu-kvm-0.15.0
I can confirm this has been happening for a while with libvirt, even still with 2.6.38 + latest everything. The workaround of editing the xml and upping the offset works fine, so no rush. I just have to do it ~30 times.. sed time i guess.. "It will likely make it out in qemu-kvm-0.15.0" ... Did you mean 0.14.1-r1, http://packages.gentoo.org/package/app-emulation/qemu-kvm If not, what's the ballpark timeline for .14 and .15 ? Really the concept of the patch looks very simple and low risk, I would throw that in without much hesitation.. =) Thanks.
seems fixed in qemu-kvm-0.15.0
(In reply to comment #12) > seems fixed in qemu-kvm-0.15.0 Indeed it is.
