Hi, List,
I''m trying xl create a pv guest with qcow/qcow2 image, it always fails at libxl_device_disk_local_attach.
#xl create pv_config_file
libxl: error: libxl.c:1119:libxl_device_disk_local_attach: cannot locally attach a qdisk image if the format is not raw
libxl: error: libxl_create.c:467:do_domain_create: failed to run bootloader: -3

[PATCH 00/15] Fix issue with KOBJ_ADD uevent versus disk attributes
This is an attempt to fix the issue that some disks' sysfs attributes are not
ready at the time its KOBJ_ADD event is sent.
The symptom is during device hotplug, udev may fail to find certain attributes,
such as serial or wwn, of the disk. As a result the /dev/disk/by-id entries are
not created.
The cause is device_add_disk emits the uevent before returning, and the callers
have to create

[PATCH v2 00/12] gendisk: Generate uevent after attribute available
The race condition is noticed between disk_add() and disk attributes, on
virtio-blk hotplug.
Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that
point we haven't created the serial attribute file, therefore depending
on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get
created.
As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk
