Created attachment 917923 [details] /var/log/libvirt/qemu/$vmname.log Creating as per https://bugzilla.redhat.com/show_bug.cgi?id=667345 and copying details from there. Description of problem: Attempting to create a ppc vm fails with error message and traceback. Version-Release number of selected component (if applicable): virt-manager version 1.0.1 libvirt version 1.1.3.5 qemu version 1.6.2 How reproducible: Always. Steps to Reproduce: 1. Attempt to create a machine and set architecture to ppc. 2. Add an install image (iso) for PPC. 3. Click "begin installation". Actual results: Error message: Unable to complete install: 'internal error: process exited while connecting to monitor: qemu-system-ppc: -device piix3-usb-uhci,id=usb,bus=pci,addr=0x2: Bus 'pci' not found ' and this traceback: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 91, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1787, in do_install guest.start_install(meter=meter) File "/usr/share/virt-manager/virtinst/guest.py", line 403, in start_install noboot) File "/usr/share/virt-manager/virtinst/guest.py", line 467, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2897, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: internal error: process exited while connecting to monitor: qemu-system-ppc: -device piix3-usb-uhci,id=usb,bus=pci,addr=0x2: Bus 'pci' not found /var/log/libvirt/qemu/$vmname.log and libvirt xml are attached. Expected results: Working PPC emulation. Additional info: This bug was originally reported for Fedora 14 by Helmut Schlattl and was previously closed after some initial efforts due to the EOL of Fedora 14.
My apologies, I cannot provide libvirt xml because virt-manager does not create it as far as I can tell. It is not present anywhaere in /etc/libvirt, at any rate.
The only powerpc version that libvirt likely works with is qemu-system-ppc64 -M pseries, the rest very likely libvirt has incorrect assumptions. FWIW that's what virt-manager will select by default if you choose arch=ppc64. Anything else at this point is probably better served by googling for a working qemu command line and using it manually.
The bus not found error should be fixed in libvirt 1.2.4 by: commit 27b2b987bf41ba1ba3aab8c8d9b2d8bc740fd925 Author: Daniel P. Berrange <berrange@redhat.com> CommitDate: 2014-04-24 14:21:39 +0100 Fix pci bus naming for PPC Recent discussions around naming of 'pci' vs 'pci.0' for PPC made me go back and look at the PPC emulator in every historical version of QEMU since 1.0. The results were worse than I imagined. This patch adds the logic required to make libvirt work with PPC correctly with naming variations across all versions & machine types. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> git describe: v1.2.3-168-g27b2b98 contains: v1.2.4-rc1~59
Oh, hmm, I was confused, I assumed -M bamboo didn't have PCI. Was thinking of ARM :) Though I still wouldn't be surprised if virt-manager or libvirt still have other issues generating a working -M bamboo command line
