Dave, Yeah, well, never mind. :-)
If I'd looked at the code first I'd have seen the function name and thought about which data I'd want to dump and where, I'd have figured out where the debug data came from. -Tom -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1594239 Title: After adding more scsi disks for Aarch64 virtual machine, start the VM and got Qemu Error Status in QEMU: Confirmed Bug description: Description =========== Using virt-manager to create a VM in Aarch64, Ubuntu 16.04. Add scsi disk to the VM. After add four or more scsi disks, start the VM and will got Qemu error. Steps to reproduce ================== 1.Use virt-manager to create a VM. 2.After the VM is started, add scsi disk to the VM. They will be allocated to "sdb,sdc,sdd....." . 3.If we got a disk name > sdg, virt-manager will also assign a virtio-scsi controller for this disk.And the VM will be shutdown. 4.Start the VM, will see the error log. Expected result =============== Start the vm smoothly.The added disks can work. Actual result ============= Got the error: starting domain: internal error: process exited while connecting to monitor: qemu-system-aarch64: /build/qemu-zxCwKP/qemu-2.5+dfsg/migration/savevm.c:620: vmstate_register_with_alias_id: Assertion `!se->compat || se->instance_id == 0' failed. details=Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 90, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 126, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1402, in startup self._backend.create() File "/usr/local/lib/python2.7/dist-packages/libvirt.py", line 1035, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error: process exited while connecting to monitor: qemu-system-aarch64: /build/qemu-zxCwKP/qemu-2.5+dfsg/migration/savevm.c:620: vmstate_register_with_alias_id: Assertion `!se->compat || se->instance_id == 0' failed.
