Comment 4 Julian Sikorski 2011-03-04 16:56:38 EST
qemu does not build with that patch applied.
Comment 5 Ian Pilcher 2011-03-07 12:02:17 EST
The package does build if "--with x86only" is added to the rpmbuild command.
I'm not familiar with the qemu build process, so I can't say whether this is
just a build process issue or a more fundamental problem.

I am able to build the full set of qemu packages with this patchset:


SPICE is working with a Windows 7 guest.
Comment 8 Fedora Update System 2011-03-17 11:40:15 EDT
qemu-0.14.0-3.fc15 has been submitted as an update for Fedora 15.
Comment 9 Mark Chandler 2011-03-17 20:21:57 EDT
Using qemu-0.14.0-3 from the fedora-virt-preview repo on F14.
Loading the QXL (0.6.1) drivers onto an XP VM still crashes qemu-kvm with the following message in the VM's log:
"qemu-kvm: /builddir/build/BUILD/qemu-kvm-0.14.0/qemu-kvm.c:1724: kvm_mutex_unlock: Assertion `!cpu_single_env' failed."
Comment 10 Fedora Update System 2011-03-18 11:20:14 EDT
qemu-0.14.0-4.fc15 has been submitted as an update for Fedora 15.
Comment 11 Mark Chandler 2011-03-19 02:36:40 EDT
Works for me now. Windows XP SP3 VM loads the 0.6.1 drivers without crashing.
Comment 12 Julian Sikorski 2011-03-19 06:52:22 EDT
Win 7 Pro works as well - I am testing using the packages from virt-preview repo.
Comment 13 Fedora Update System 2011-03-23 01:02:20 EDT
qemu-0.14.0-4.fc15 has been pushed to the Fedora 15 stable repository.  If problems still persist, please make note of it in this bug report.
