[Bug 1223907] Re: qemu-kvm crashes in qcow2 code
True. However I do need the debug symbols for the PATCHED qemu-kvm package, specifically for the ppa2 version. These symbols are of course not in the official ddebs repos and also not in the PPA. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1223907 Title: qemu-kvm crashes in qcow2 code To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1223907/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
