[Qemu-discuss] block.c - assertion failed

[Markus Stockhausen]

Hello,

we hit the following error this morning in one of our VMs on qemu 1.6.2 (FC20 distro):

qemu-system-x86_64: block.c:2806: bdrv_error_action: Assertion `error >= 0' failed.

2014-06-30 08:40:11.686+0000: shutting down

Form reading the code at the mentioned location I assume there should be some

further details to find.

...

void bdrv_error_action(BlockDriverState *bs, BlockErrorAction action,

                       bool is_read, int error)

{

    assert(error >= 0);

    bdrv_emit_qmp_error_event(bs, QEVENT_BLOCK_IO_ERROR, action, is_read);

    if (action == BDRV_ACTION_STOP) {

        vm_stop(RUN_STATE_IO_ERROR);

        bdrv_iostatus_set_err(bs, error);

    }

}

...

Qemu is started with libvirt so these are the only logs I found. Any idea where to 

search next?

Markus
