Re: Fail in virDomainUpdateDeviceFlags (libvirt-4.0.0 + Qemu-kvm 2.9.0 + Ceph 10.2.10)
...pts the device if provided). AFAICT, the "id"
option is not used in libvirt yet. The block_set_io_throttle being the
example I looked at.
Following the code for using the "id" option, I see no connection to the
secret object which would store the server passphrase.
So when the bdrv_open is called from qmp_blockdev_change_medium, there
is no way to "connect" to the alias.
If it happens differently than that, then please show me what I'm missing.

Dear Michal
After I fix the local libvirt master branch follow your patch, and build rpm
for CentOS 7.4. virDomainUpdateDeviceFlags as bellow:

[RFC][PATCH] Use ioemu block drivers through blktap
When I submitted the qcow2 patch for blktap, suggestions came up that
the qemu block drivers should be used also for blktap to eliminate the
current code duplication in ioemu and blktap.
The attached patch adds support for a tap:ioemu pseudo driver. Devices
using this driver won''t use tapdisk (containing the code duplication)
any more, but will connect to the qemu-dm of the domain. In
