https://bugzilla.kernel.org/show_bug.cgi?id=61971 Magnus Boden <magnus@boden.cx> changed: What |Removed |Added ---------------------------------------------------------------------------- Kernel Version|3.10.5 |3.11.1 --- Comment #1 from Magnus Boden <magnus@boden.cx> --- Hello, Since the kernel I used was a debian backport I compiled my own kernel from kernel.org 3.11.1 and it has the same problem. Regards Magnus
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #2 from Magnus Boden <magnus@boden.cx> --- Hello, For testing I took an old machine and installed it like the other two except no need for local storage so no glusterfs. gluster volumes are mounted from the other servers. Migration Node A -> (B OR C) Guest freeze Node (B OR C) -> Node A works Node B <-> C Works Any debugging or troubleshooting steps I can do I am happy for any pointers in the right direction. Regards Magnus
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #3 from Magnus Boden <magnus@boden.cx> --- Can anyone help with troubleshooting this further? Regards Magnus

What "info status" shows when guest freeze? Can you try latest qemu?
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #5 from Magnus Boden <magnus@boden.cx> --- Hello, It says this, I haven't found any easy way to upgrade to later versions of qemu in debian but I will try compiling it from source. I did try 1.4.0 and 1.5.0 in ubuntu before reverting back to my prefered distro debian. virsh # qemu-monitor-command --hmp lazy "info status" VM status: running Thanks Magnus
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #6 from Magnus Boden <magnus@boden.cx> --- Sorry missed to answer your question: So new to old always hangs? Yes it always hangs.

https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #11 from Paolo Bonzini <bonzini@gnu.org> --- This is XSAVE -> non-XSAVE migration. Alexander Graf reported to me on IRC that the XSAVE patches we recently committed to kvm/next fixed this for him. xstate_bv is saved as 7 and this check fails on the destination: if (xstate_bv & ~XSTATE_FPSSE) return -EINVAL; I think it is because your CPU has xsave but not xsaveopt. However, those patches introduced regressions that have to be fixed. I'll look at those soon, but your bug should get fixed in 3.13.
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #12 from Magnus Boden <magnus@boden.cx> --- Perfect. Thanks for the response. I will try 3.13 as soon as it is released. If you need any beta testing I am available.

The bugs that is there may not affect your case.
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #14 from Magnus Boden <magnus@boden.cx> --- I will try that. I am going away tonight but I will try it tomorrow and report back tomorrow evening. Thanks for the support Magnus
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #15 from Magnus Boden <magnus@boden.cx> --- I have no upgraded all three hosts with the kernel from git://git.kernel.org/pub/scm/virt/kvm/kvm.git Using the branch next, last commit on that tree was: commit d570142674890fe10b3d7d86aa105e3dfce1ddfa Merge: f2e1066 a7265fb Author: Gleb Natapov <gleb@redhat.com> Date: Wed Oct 16 15:30:32 2013 +0300 Merge tag 'kvm-arm-for-3.13-1' of git://git.linaro.org/people/cdall/linux-kvm-arm into next Updates for KVM/ARM including cpu=host and Cortex-A7 support Now the symptoms are the other way around. Migrations B or C to A guests freeze (both freebsd and linux tested). Migrations A to B or C works. Regards Magnus
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #16 from Paolo Bonzini <bonzini@gnu.org> --- Yes, that's expected. You also need the patch I send on Thursday, that you were CCed on (KVM: x86: fix KVM_SET_XCRS for CPUs that do not support XSAVE).
https://bugzilla.kernel.org/show_bug.cgi?id=61971 --- Comment #17 from Magnus Boden <magnus@boden.cx> --- Sorry I missed the patch. I have patched my kernel now and can report that migrations work in every direction between my three hosts. Thanks very much for the support Magnus
