This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'. If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

I no longer have the original natty-desktop-i386.iso, and the current one appears to have moved some of the breakpoints. So I instead tested using this bug's dup, 771227. virsh save/restore are working with this proposed kernel.

Building a kernel with emulate_int_real removed, I assume that will start working. I suspect the right answer will just be to increment eip, of course, i.e. something like insn_fetch(s8, 1, c-eip). -- 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/747090 Title: wrong return address sometimes pushed for INT in kvm (not qemu) -- 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
