Hi, during internal testing of Qemu 2.5.1.1 I found a vServer running Ubuntu 12.04 (kernel 3.13) and a slave SQL server to stop replicating from the master. This seems to be reproducible. It is possible to continue replication when issuing a slave stop / slave start. There is no error visible on the vServer.
Has anyone a fix in mind that could be related to such an issue? Host kernel in Linux 4.4, Guest kernel 3.13. Guest driver is virtio-blk via iSCSI. Emulated vCPU is Westmere. I already have this patch here applied: target-i386: do not read/write MSR_TSC_AUX from KVM if CPUID bit is not set Without this migration for Westmere and earlier CPUs is completely broken. I also found the following commits in git which are not applied (yet): migration (ordinary): move bdrv_invalidate_cache_all of of coroutine context migration: fix incorrect memory_global_dirty_log_start outside BQL I will try with these and also with current master. Thanks, Peter
