Description David Gibson 2015-04-08 04:24:47 UTC

Description of problem:

I have virt-manager on an x86 Fedora machine connecting to a qemu backend on a ppc64le machine.  I have VMs installed by other means (virt-install) on the backend machine, but I am unable to open and view these VMs from virt-manager.

Version-Release number of selected component (if applicable):

virt-manager-1.1.0-5.git310f6527.fc21.noarch

How reproducible:

100%

Steps to Reproduce:
1. Create a connection with a qemu+ssh URL connecting to a ppc64le host.
2. Create VMs on this host via any means (virt-manager itself won't work due to bug 1209720)
3. Double-click on one of the VMs

Actual results:

An error message pops up saying: "Error launching details: invalid argument: architecture from emulator 'ppc64' doesn't match given architecture 'ppc64le'"

Expected results:

Normal VM window opens giving access to VM configuration and console.

Thanks for the report. This is the backtrace:

Traceback (most recent call last):

    details = self._get_details_dialog(uri, vm.get_connkey())

    if ret is None: raise libvirtError ('virConnectGetDomainCapabilities() failed', conn=self)
libvirtError: invalid argument: architecture from emulator 'ppc64' doesn't match given architecture 'ppc64le'

Looks like a libvirt issue, I'll create a bug for that. but we can ignore the error in virt-manager

Comment 7 David Gibson 2015-04-20 01:03:11 UTC

I downloaded and tried virt-manager-1.1.0-7.git310f6527.fc21.  I now get a different error when I try to open the VM details window:

Error launching details: global name 'logging' is not defined
