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.
After a lot of testing I found out that obviously thats no block driver
problem, but a regression in the virtio-net or the network stack.
qemu_announce_self() is generating packets for all NICs, but it seems they are
no longer emitted. This worked at least in qemu-2.2.0 with
the same guest kernel and host kernel.
I will continue debugging tomorrow why this happens.
