>>Is it only with 3.16 kernel? Haven't seen this yet. Yes, I have reproduce it on 3 debian jessie kernel 3.16.
But other jessie migration have worked before... I have asked to the qemu mailing, waiting for more information. ----- Mail original ----- De: "Stefan Priebe" <[email protected]> À: "aderumier" <[email protected]> Cc: "pve-devel" <[email protected]> Envoyé: Vendredi 28 Août 2015 17:07:07 Objet: Re: [pve-devel] qemu kvm_steal_time bug Is it only with 3.16 kernel?

The bug is that after a live migration, the steal cpu counter just freeze at 100% # mpstat Linux 3.16.0-4-amd64 (radinsapi1) 28/08/2015 _x86_64_ (8 CPU) 16:24:51 CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle 16:24:51 all 0,00 0,00 0,00 0,00 0,00 0,00 99,92 0,00 0,00 0,08 Seem to be a qemu bug, the workaround seem to use -kvm_steal_time cpu flag. But I don't known if they are an performance impact or not. Does somebody already have had this bug ?
