It is attached to the message which has a highest quoting order above 1), basically it is a monkey adaptation of newer ioapic patches for 3.10. RH kernel includes them, so Centos7/RH7 users should not observe reported problem. [1] https://www.mail-archive.com/qemu-devel@nongnu.org/msg252526.html Using the opportunity - what are plans, if there are any, to revive agraf`s patch which was the reason of an initial issue in this thread? The Windows issue is most probably unrelated to it and I`d be happy to check patch proposals because there are a lot of suffering with VMs with large uptime and live migration when negative time shift appears.
