surprising <backingStore type='file'> setting in domain.xml
Hello all.
My currently used versions: libvirt-5.2.0 and qemu-4.0.0.
Here is my problem. I'm struggeling since a few weeks with a strange
behaviour by either qemu or libvirt. After a reboot of
the hardware node the $domain.xml contains suddenly a backingStore
setting which was not there before reboot.
Something like that:
<devices>
<emulator>/usr/bin/qemu-system-x86_64</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source

Whether libvirt can support all backing chain layer are iscsi network disk type
...etwork disk type , such as
iscsi://ip/iqn../0(base image) <-iscsi://ip/iqn../1(active image).
Currently, 'qemu-img info --backing-chain' command can display correct
backing file info, but after starting guest with the active image in
backing chain, it don't include the related <backingStore> element in
dumpxml.
So, Whether libvirt can support all backing chain layer are iscsi
network disk type?

Cannot create qcow2 images with libvirt 0.8.1
...or : virStorageBackendCreateExecCommand:537 : Cannot run /usr/bin/qemu-img
to create /data/testserverb-data.img: Invalid argument
error : qemudClientReadBuf:1653 : gnutls_record_recv: A TLS packet with
unexpected length was received.
If I leave out the <format> element and/or specify a <backingStore> element
for the volume, it works again. (I suppose the backing store makes it work
because in that case qemu-img does not need a size parameter...)
The host system is a vanilla Fedora Core 12 system (aside from the upgraded
libvirt).
