[Qemu-discuss] Latest Qemu-COLO Segfaults when failover

[wenzt]

Hi, Zhang:

 

When I create PVM with:

-drive
if=virtio,id=primary-disk0,driver=quorum,read-pattern=fifo,vote-threshold=1,
children.0.file.filename=...

 

SVM with:

-drive if=ide,id=secondary-disk0,file.filename=...

 

I got this ERR: qemu-system-x86_64: block.c:5062: bdrv_detach_aio_context:
Assertion `!bs->walking_aio_notifiers' failed.

 

I changed if=virtio to ide on both PVM and SVM, it works fine.

 

When I test failover with: {"execute": "x-colo-lost-heartbeat"} on SVM.

I got this ERR: Conflicts with use by a block device as 'root', which does
not allow 'resize' on node0.
