Thanks a lot. Peter . BTW, one more question, recently sometimes we often hit
another issue that vm can’t boot from disk stuck in black screen show “Guest
has not initialized the display (yet).”
Our QEMU command line parameter like below.
/usr/bin/qemu-system-x86_64 -name

Hi Guys:
Who can help me ? What does this issue mean? When I attach a network I hit
this issue.
libvirt: QEMU Driver error : internal error: unable to execute QEMU command
'netdev_add': Invalid parameter type for 'vhost', expected: boolean
Thanks!

Thanks all of you for your help.
One more question regarding vhost-user-blk-pci type device, how to identify a
vhost-blk disk in QEUM VM ? for example, disk name looks like vda,vdb,..., but
that some application in VM want to detect that a certain entry is really the
device it is waiting

Thanks Michal and Peter for your response. I‘ m running it on qemu 5.1 build by
myself. BTW, follow Peter’s suggestion, where I can get the latest rpms if I
want to upgrade to Libvirt 7.1? As I know it seems need more than twenty
related rpms not include dependency.

Thanks，I have tried qemu monitor as below. I used chardev_add to add a chardev
and used device_add it to running vm. But i often hit a issue and cause the vm
crash. qemu-system-x86_64: ../hw/virtio/vhost.c:1566: vhost_dev_get_config:
Assertion `hdev->vhost_ops' failed.

Manual approach is to use 'virsh qemu-monitor-command' or
Thanks Peter for your quickly response. Is there any workaround to do that？As
you know we must take care the risk of using latest version in product
environment.
Thanks a lot!

Hi Guy,Does anyone clear how to hot plugin a new vhost-user-blk-pci device to a running VM?Before staring vm , I pass the disk through QEMU command line like below. But I don’t know how to live add a vhost-user-blk-pci device on running VM even with calling attachDevice
Hi Guy,
Does anyone clear how to hot plugin a new vhost-user-blk-pci device to a
running VM?
Before staring vm , I pass the disk through QEMU command line like below.
But I don’t know how to live add a vhost-user-blk-pci device on running VM even
with calling attachDevice API
