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
