This is Kevin from Linaro, and recently I have met a problem of qemu-system-aarch64 when I am working on virt-manager. I have reported a bug here: https://bugs.launchpad.net/qemu/+bug/1594239 It's mainly bout adding several SCSI disks to Aarch64 guests.

Sounds like maybe we just increased the error checking on our command lines -- you can't have more than one device with the same ID. I can't tell what the other device with the same ID is, because this doesn't give all the command line. If libvirt is generating invalid command lines, that would be a libvirt bug. thanks -- PMM ^ permalink raw reply [flat|nested] 11+ messages in thread

I change the /var/lib/libvirt/qemu/nvram/f23_VARS.fd to another directory so that qemu can access it,and no permission denied error again. Thank Cole. All: With the Qemu 2.6.50 and libvirt(commit 03ce1328086d6937d2647d616efff29941a3e80a): *I find that the problem that I have met before occurs again. I can reproduce it.* 1. After launching a VM with fedora23(for example), the xml is f23.xml in attachment. 2. Then use qemu-img command to generate a qemu disk f23-2.qcow2 and f23-3.qcow2 3. Add f23-2.qcow2 as sdc. $ ./virsh attach-device f23 /root/sdc.xml sdc.xml : <disk type="file" device="disk"> <driver name="qemu" type="qcow2"/> <source file="/var/lib/libvirt/images/f23-2.qcow2"/> <target dev="sdc" bus="scsi"/> </disk> Then in the Guest f23, we can see it takes effect immediately. 4. Add f23-3.qcow2 as sdh , also add virtio-scsi controller for sdh. $ ./virsh edit f23 add this below <controller type="scsi" index="1" model="virtio-scsi"/> <disk type="file" device="disk"> <driver name="qemu" type="qcow2"/> <source file="/var/lib/libvirt/images/f23-4.qcow2"/> <target dev="sdh" bus="scsi"/> </disk> $ ./virsh destory f23 && ./.virsh start f23 Got the error: 2016-06-28 11:37:17.017+0000: 6329: warning : qemuDomainObjTaint:3227 : Domain id=15 name='f23' uuid=e2de65f4-5d9a-4b90-a56a-ae40f4763aec is tainted: high-privileges 2016-06-28 11:37:17.017+0000: 6329: warning : qemuDomainObjTaint:3227 : Domain id=15 name='f23' uuid=e2de65f4-5d9a-4b90-a56a-ae40f4763aec is tainted: host-cpu 2016-06-28 11:37:28.546+0000: 6313: error : qemuMonitorIORead:583 : Unable to read from monitor: Connection reset by peer 2016-06-28 11:37:28.546+0000: 6313: error : qemuProcessReportLogError:1815 : internal error: qemu unexpectedly closed the monitor: qemu-system-aarch64: /opt/stack/kevin/qemu/migration/savevm.c:615: vmstate_register_with_alias_id: Assertion `!se->compat || se->instance_id == 0' failed. *So this bug seems exist with new qemu and new libvirt. * > > - Cole > > [-- Attachment #2: f23.xml --] [-- Type: text/xml, Size: 1298 bytes --] <domain type="kvm"> <name>f23</name> <uuid>bf74479b-76da-4a84-962a-576394901f3a</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>1</vcpu> <os> <type arch="aarch64" machine="virt">hvm</type> <loader readonly="yes" type="pflash">/usr/share/AAVMF/AAVMF_CODE.fd</loader> <nvram>/var/lib/libvirt/images/f23_VARS.fd</nvram> <boot dev="cdrom"/> <boot dev="hd"/> </os> <cpu mode="host-passthrough"/> <clock offset="utc"/> <on_poweroff>destroy</on_poweroff> <on_reboot>destroy</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type="file" device="disk"> <driver name="qemu" type="qcow2"/> <source file="/var/lib/libvirt/images/f23.qcow2"/> <target dev="sda" bus="scsi"/> </disk> <disk type="file" device="cdrom"> <driver name="qemu" type="raw"/> <source file="/var/lib/libvirt/images/Fedora-Server-DVD-aarch64-23.iso"/> <target dev="sdb" bus="scsi"/> <readonly/> </disk> <controller type="scsi" index="0" model="virtio-scsi"/> <interface type="network"> <source network="default"/> <mac address="52:54:00:ce:48:26"/> <model type="virtio"/> </interface> <console type="pty"/> </devices> </domain> ^ permalink raw reply [flat|nested] 11+ messages in thread

Hi Kevin, The assert you've got there really should not happen: 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. I've only seen that error once before, and that was when the device had a really long device path (lots and lots of PCI bridges) but you've not got that. Can you get a full backtrace from that? If you can rebuild it and debug then adding some prints into vmstate_register_with_alias_id should help, in particular if you can print the name that qdev_get-dev_path returns it would be good and also the vmsd->name value.

In this condition, there are more than 1 virtio-scsi controllers for the guests will induce this error. I'm not familiar with Qemu development. I will try to rebuild it and get more debug info.
